Lightning and surge protection for control and instrumentation signals
Basic classification
The current scope of automation
technology has resulted in a wide range
of applications for surge protection
in the field of instrumentation and
control engineering. One important
prerequisite is the consistent use of
coordinated surge protection in all
sections of the plant or building. In
industry, instrumentation and control
systems are important areas and
Transient surges coupled into a system
via one or more coupling mechanisms
occur as normal- or common-mode
interference. These are measured as
longitudinal or transverse voltages and,
depending on the circuit, designated as
symmetrical or asymmetrical voltages.
(For further information see the
“Principles” chapter.)

(symmetrical loop)
These are two-wire signals with a
common reference potential which are
required by, for example, by switches,
PLC switch outputs, photoelectric
barriers, position sensors, solenoid
valves, warning lamps, PLC inputs,
etc. Normally, these signals have a
common reference potential that can
be either connected or not connected
to earth potential, depending on
the type of protection. The coupled
transient interference is primarily
common-mode interference.

Normal-mode interference
(symmetrical interference):
Normal-mode voltage between supply and
return conductor load and interference
source connected in series, e.g. inductive
(magnetic field) or conductive coupling
(common impedance)
Measuring circuits are normally
designed as two-wire current loops
or voltage signals without a common
reference potential, like the
0(4)...20 mA current loop.
The coupled transient interference is
primarily normal-mode interference.
For temperature measurements with
the PT100 measuring shunt in the
three-wire version, the voltage drop
at the shunt is measured via the third
wire. This must be included in the
system of protection.
The PT100 measuring shunt is also
available in a four-wire version in
which the voltage drop at the shunt is
measured via the two additional lines
without additional line losses in the
PT100 measuring circuit. The coupled
transient normal-mode interference
occurs between the various wires.

Essential information for users can be found in the IEC 61643-22 standard (application standard for measurement and
control signals) and in the IEC 62305-4 standard (application standard for installing internal lightning protection).
It is important to determine which protection category is required. There are divisions for D1 (lightning protection), C2 (surge
protection / overvoltage protection) and C1 (end device protection). These categories or classes are specified for the
following products. All products were subjected to a test in accordance with product standard IEC 61643-21.

VARITECTOR SPC
VARITECTOR SPC
Pluggable lightning and surge protection for measurement and control circuits
Pluggable lightning and surge protection for 2 analogue signals or
4 binary signals in measurement/control circuits – with integrated error
detection and alert functions in only 17.8 mm width.
B
Our pluggable VARITECTOR SPC surge protection is characterised by highest
protective functions with compact dimensions. The arrestor of the modules can
be removed, measured or exchanged during running operation impedance-neutral
– without interrupting the measuring circuit. These features make this product
the ideal secure protection mechanism for interfaces within instrumentation and
control circuits.
Maintenance intervals are simplified by the V-TEST test unit, which is used for
testing the function of the VARITECTOR SPC. This test method satisfies the
requirements of standard IEC 62305.
With the VARITECTOR SPC R modules, error detection and error messages are
realised by internal monitoring. The green LED indicates the active protective
function. The red LED indicates a fault condition. This information is transmitted
to the V-Control evaluation unit. From there, the information can be sent across
to e.g. a controller.
Due to the impedance-neutral removing of the arrestor, the VARITECTOR SPC
modules can be used instead of terminals. For four binary signals or
two analogue signals, just 17.8 mm of space on the mounting rail is used.
By simply snapping onto a grounded mounting rail, time savings are also
ensured when connecting. A colour code identifies the various voltage
levels for all VARITECTOR SPC modules. This simplifies maintenance
work during operation. The EMC set offers additional convenience for
connecting shielded cables. All VARITECTOR products comply with the
latest IEC 61643-21requirement for a new overstress mode.

VARITECTOR SPC
Pluggable surge protection for the
measurement and control industry
VARITECTOR SPC
Weidmüller's VARITECTOR SPC
pluggable surge protection is
remarkable for its combination of
extremely high protective functionality
and compact dimensions. It is suited
for use in measurement and control
circuits. The size is made possible by
the seletion of INSTA dimensions, with
a width of 17.8 mm (1TE).
Two versions are available:
•VSPC: a surge protector
with no monitoring function
•VSPC R: a surge protector
with monitoring function
The base components are plugged in
to form a direct earthing contact via
the mounting rail. This saves you time
when making the connection. The
VARITECTOR SPC series is optimally
designed for compact installations
in process automation, industrial
automation and building automation.
The two-stage surge-protection base
components are equipped with gas
discharge tubes, suppressor diodes
(TVS) and decoupling components.
Individual protective components
(such as gas-filled spark gaps, varistors
and suppressor diodes) supplement
this product line. IEC 62305 requires
that a periodic inspection of surge
protection products be conducted.
The functionality of all VARITECTOR
SPC modules can be tested using
testing equipment (such as the V-TEST
Basic) that is available separately. The
VARITECTOR SPC R modules also
feature an internal monitoring function.
The green LED signals when the
protection function is ready.
The red LED signals an error.
B.10
Up to ten modules can be wired
together in succession. The modules
alert an evaluative module (the
VSPC CONTROL UNIT) in the event
of an error. VARITECTOR SPC series
surge protection is available with rated
voltages of 5 V, 12 V, 24 V, 48 V and
60 V. The product's voltage level is
colour-coded on the pluggable arrester.
An earthing contact is established by
snapping onto an earthed TS 35 rail.
The TS 35 must be earthed in order to
ensure safe power discharging via the
terminals of up to 20 kA (8/20 μs) and
2.5 kA (10/350 μs). The rail must be
screwed onto the earthed mounting
plate for reasons of EMC. In order to
optimise the protective function, a
PE-contact connection should be made
over the VSPC module every 60 cm for
equipotential bonding. The pluggable
protective element can be pulled out
during operations without interrupting
the measurement circuit. A testing
instrument, available as a Weidmüller
accessory, allows you to test the
protective element in compliance with
the IEC 62305-3 directive.
The accessory also includes a simple
mechanism for applying the wire shield.
Overview of model types
A VARITECTOR SPC (VSPC) consists
of a pluggable component and a
separate base component
(VSPC BASE).
Explanation of terms:
CL = current loop / analogue signals
SL = symmetric loop - for binary signals
VSPC 2CL
VSPC 2CL (CL = current loop) is a
two-stage protective combination with
a gas discharge tube and a suppressor
diode located between the current
paths. This VSPC 2CL limits the surge
voltage within two analogue signal
circuits (such as for current loops).
This pluggable component can be
inserted into the base (VSPC BASE
2CL). The base (VSPC BASE FG 2CL) is
used when working with signal circuits
which are not earthed. The VSPC 2CL
HF is used in order to avoid influencing
high-frequency signal circuits (this
also includes the VSPC RS485 and
the VSPC UK0). This protective
combination is also inserted into the
base mentioned above.
Monitoring function
The VSPC 2CL R products feature
monitor and alert functions. As well
as the alert function, there are two
channels available for current loops in a
single housing. The special VSPC BASE
2CL R and SPC BASE 2CL FG R bases
2028840000
Lightning and surge protection
for control and instrumentation signals
VARITECTOR SPC
transfer the alert function to a 2-pole
screw/plug-in connection in the bases
and to the VSPC CONTROL UNIT.
VSPC 1CL
The VSPC 1CL is a two-stage
protective combination with a gas
discharge tube and a suppressor diode
located between the current paths.
This VSPC 1CL limits the surge voltage
within one analogue signal circuit
(such as for current loops). This
pluggable component can be inserted
into the base (VSPC BASE 1CL).
The base (VSPC BASE FG 1CL) is used
when working with signal circuits
which are not earthed.
Monitoring function
The VSPC 1CL R products feature
monitor and alert functions. All
channels remain despite the alert
function. The special VSPC BASE 1CL
R and VSPC BASE 1CL FG R bases
transfer the alert function to a 2-pole
screw/plug-in connection in the bases
and to the VSPC CONTROL UNIT.
VSPC 4SL
The VSPC 4SL is a two-stage
protective combination with a gas
discharge tube and a suppressor diode
from the current path to the PE. This
VSPC 4SL limits the surge voltage
within four binary signal circuits
(such as for alert contacts). This
pluggable component can be inserted
into the base (VSPC BASE 4SL).
The base (VSPC BASE FG 4CL) is used
2028840000
when working with signal circuits
which are not earthed.
Monitoring function
The VSPC 4SL R products feature
monitor and alert functions. Even
with the alert function, there are still
channels available for the four binary
signal circuits in a single housing.
The special VSPC BASE 4SL R base
transfers the alert function to a 2-pole
screw/plug-in connection in the base
and to the VSPC CONTROL UNIT.
The VSPC 3/4WIRE is a two-stage
protective combination with a gas
discharge tube and a suppressor diode
from the current path to the GND. This
VSPC 3/4WIRE limits the surge voltage
within four temperature-measurement
circuits (such as for DMS or
PT100/100 sensors). For non-earthed
measurement circuits, we recommend
using the base (VSPC BASE FG 4CL).
B
VSPC GDT
VSPC 2SL
The VSPC 2SL is a two-stage
protective combination with a gas
discharge tube and a suppressor diode
from the current path to the PE. This
VSPC 2SL limits the surge voltage
within two binary signal circuits
(such as for alert contacts). This
pluggable component can be inserted
into the base (VSPC BASE 2SL).
The base (VSPC BASE 2CL FG) is used
when working with signal circuits
which are not earthed.
VSPC MOV 2CH , VSPC TAZ 2CH
and VSPC GDT 2CH
Four cables can be protected with
the 2CH modules. By wiring the
connections differently, either two novoltage signal lines or four binary signal
lines can be protected. Two three-pole
gas discharge tubes (GDTs) are used
for the VSPC GDT 2CH. This universal
protective circuitry limits the voltage
between the signal lines and also
between each signal line and the PE.
Monitoring function
The VSPC 2SL R products feature
monitor and alert functions. Even
with the alert function, there are still
channels available for the two binary
signal circuits in a single housing.
The special VSPC BASE 2SL R base
transfers the alert function to a 2-pole
screw/plug-in connection in the base
and to the VSPC CONTROL UNIT.

VSPC TAZ
VSPC MOV
The VSPC MOV 2CH and TAZ 2CH
offer one-stage protection with a
varistor (MOV) or suppressor diode
(TAZ or TVS) between the current
paths. This makes it possible to protect
a no-voltage (floating) signal circuit.
Two binary signal circuits can also
be protected if terminals 1 and 7 are
assigned to GND / PE. These VSPC
pluggable components are inserted
into the base (VSPC BASE 2/4CH).
The base (VSPC BASE 2/4CH FG) is
used when working with signal circuits
which are not earthed.
24 V
VSPC 1CL PW
VSPC 1CL PW (power and signal
1CL) offers combined protection that is
suitable for the 24 V DC power supply
and the current loops within a device.
This VSPC protects sensors with an
additional 24 V DC.
B.12
VSPC RS422/485
The VSPC RS485 is a two-stage
protective combination with a gas
discharge tube and a suppressor diode
located between the current paths. This
VSPC RS485 limits the surge voltage
within two high-frequency signal
circuits. This pluggable component
can be inserted into the base
(VSPC BASE 2CL). The base
(VSPC BASE FG 2CL) is used when
working with signal circuits which are
not earthed.
Monitoring function
The VSPC RS485 R product features
monitoring and alert functions. Even
with the alert function, there are still
two channels available for current
loops in a single housing. The special
VSPC BASE 2CL R and VSPC BASE 2CL
FG R bases transfer the alert function
to a 2-pole screw/plug-in connection in
the bases and to the
VSPC CONTROL UNIT.
Earthing unit and test plug
The earthing unit can be used
during installation to short out the
connected wires to earth. The earthing
unit is swapped out for a VSPC
pluggable component before the
initial commissioning. The test plug
has 2.3-mm sockets. These sockets
can be used by a meter to check the
connected measurement circuit.
The pluggable INSTA housing was
created in compliance with DIN 43880.
It consists of a lower section
(the VSPC BASE) and a pluggable
component (the VSPC). The VSPC
BASE is made from black PA6.6 V0.
The pluggable component is made
from red PA6.6 V0. The temperature
range is from -40 °C to + 70 °C.
The VSPC series has been tested to
comply with IEC 61643-21 04/2008
and EN 61643-21. Modules were
tested with categories C1, C2 and C3:
with quick-rising edges with up to 300
pulses. Category D1 describes high
power testing (10/350 μs lightning
protection), so that the VSPC can be
used according to IEC 62305-4.
The base and pluggable components
are colour coded according to the
voltage level. This makes installation
easier.
Colour coding
The pluggable components transfer
their coding to the base element when
they are plugged in for the first time.
The voltage levels are also labelled with
coloured Dekafix markers applied to
the VSPC pluggable component. This
gives you a better overview within the
electrical cabinet.

Test possibility / V-TEST
Because the modules are pluggable,
it is possible to test the VSPC visually
or by using a V-TEST testing device.
The VSPC can be easily tested; the
user needs only to insert the VSPC
pluggable component into the V-TEST.
The result is then shown on the display.
The VSPC R modules also feature an
internal monitoring function for the
arrester. An error is the displayed at the
defective module. The VSPC CONTROL
UNIT can then transfer an alert to the
control room.

inserted into the corresponding “R”
base component, it is then possible
to use the outage alert function via
a two-pole plug. This screw/plug-in
connection has a clamping range from
0.5 to 1.5 mm².
The wire stripping length is
6 to 6.5 mm. A screwdriver with
a 2-mm blade width is used to
turn the screw. The VSPC Rs are
connected in succession to the
VSPC CONTROL UNIT evaluative
module. Up to ten VSPC Rs can
be connected in succession to the
VSPC CONTROL UNIT. The evaluative
module is supplied with 24 V DC. It
is then responsible for the switching
and for the voltage supply to the
VSPC modules. A no-voltage (floating)
CO contact can then be used to alert in
the event of an outage. The error on the
module, with the LED changing colour
from green to red. An automatic reset
is carried out by the VSPC CONTROL
UNIT within one minute after the
failed VSPC pluggable component is
replaced.
The VSPC series is appropriate for
protecting signal circuits. In order to
achieve a complete protective strategy
for the facility, the power feed must be
protected against Type II surge voltages
(for example, by using our VPU II
series). For existing lightning protection
facilities, Type I protection must be
used (for example, by using our VPU I
series). Type II protection (for example,
our VPU II) is sufficient when there is
no lightning protection in place.
B
Fusing
The VSPC surge protection modules are
designed so that they are decoupled
between the individual protective
stages.
The following must be observed when
providing fuse protection externally:
• Max. rated current
• Deratings curve
• Type of installation
•Application

minimised power. Category D uses
quick-rising edges and high power
to detail the interference pulses. This
energy simulates the high-power

VARITECTOR SSC 6AN
Lightning and surge protection in terminal block design
Lightning and surge protection in 6 mm overall width for
measurement and control circuits including isolation/
measuring function
The VARITECTOR SSC combined surge protection, a direct PE contact
function, separation of signal paths and operational status indication in
one module. It is suitable for C&I applications.
The disconnect lever in the terminal guarantees that the measurement/
control circuit can be quickly and precisely switched off to test the signal
path. Using a test plug (PS 2.3 mm), the measuring instrument can
be easily inserted into the integrated test socket on Torx®/Slot headed
screws. The shield can be attached onto the additional lower level of
the VSSC 6AN which then leads directly to the PE potential on the
mounting rail. Permanent shielding can be implemented easily using
the EMC set. Weidmüller’s SNAPMARK device marker can be snapped
onto a terminal so that the equipment identification can be easily read
regardless of the installation position. The VSSC 6AN features all the
advantages found in the VARITECTOR SSC product line: a thin 6.2 mm
width, quick PE contact to rail (with up to 20 kA discharge capacity),
simple colour coding for quick identification, large-surface versatile
markers, and the new Torx®/slot headed screw.
All VARITECTOR products comply with the latest IEC 61643-21
requirement for a new overstress mode and with categories D1, C3, C2
and C1 according to IEC 61643-22.
Convenient
Connection convenience is assured by a
clamping rage of 0.5 mm² to 6 mm² with
a Torx®/slot headed screw and a 0.8 Nm
tightening torque.
Space-saving
A terminal of just 6.2 mm for two binary signals
or one analogue signals. Terminals can be fitted
side by side.

VARITECTOR SSC
Surge protection in a terminal
block: for measurement and
control systems
VARITECTOR SSC
Weidmüller's VARITECTOR SSC series
for surge protection (VSSC4 and
VSSC6) is well suited for protecting
measurement and control circuits. It
features good protective functionality
in a compact terminal-block design.
This is due to its 6.2 mm width. The
combined Torx®/ slotted screw ensures
that the proper nominal or max. torque
is applied to the connection. The
required screwdrivers are available
from Weidmüller under the following
order numbers:­
4-mm slotted SD 0.8 x 4.0 x 100 (order
no. 9008340000) or T15 Torx® (order
no. 9009170000). The VSSC can be
snapped on, to directly earth it to the
DIN rail. The VSSC series is available
with four clamping yokes (VSSC4) and
six clamping yokes (VSSC6). The screw
terminal has a nominal torque of
0.5 Nm, but it can be tightened to
0.8 Nm. The VARITECTOR SSC series
is optimally designed for compact
installation locations in process
automation, industrial automation or
building automation.
The two-stage surge protection
terminals are equipped with gas
discharge tubes (GDT), suppressor
diodes (TVS) and decoupling
components. Individual protective
components (such as gas-filled spark
gaps, varistors and suppressor diodes)
supplement this product line. Our
VARITECTOR SSC surge protectors are
available for components with nominal
voltages of 12 V, 24 V, 48 V to 230 V.
Please contact us for other voltages or
special applications.
The two-stage surge protection
terminals are equipped with gas

B.66
components (such as gas-filled spark

supplement this product line. Our
VARITECTOR SSC surge protectors are
available for components with nominal
voltages of 12 V, 24 V, 48 V to 230 V.
Please contact us for other voltages or
special applications. The PE contact
is established by snapping onto an
earthed DIN rail. The TS 35 must be
earthed in order to ensure safe power
discharging via the terminals of up to
20 kA (8/20 μs) and 2.5 kA
(10/350 μs). The DIN rail must be
screwed onto the earthed mounting
plate to ensure EMC. The best
protection is achieved when a PE
contact is established every 60 cm
/ 24 inch using the terminal at the
VARITECTOR SSC terminals with direct
equipotential bonding. The cable should
correspond to the max. cross-section
of the VSSC connection. The four-port
VARITECTOR SSC terminal can be used
for binary and / or analogue signal
circuits. The six-port VARITECTOR SSC
can also be used to open signal circuits
via an isolated level and monitor them
using the optional built-in LED.
Overview of model types
VSSC4 CL
The VSSC4 CL is a two-stage
protective combination that has a
suppressor diode between the current
paths. This VSSC4 CL limits the surge
voltage in an analogue signal circuit
(e.g. a current loop).
The VSSC4 CL FG is a two-stage
protective combination that has a
suppressor diode between the current
paths. The gas discharge tube to
the PE provides a high-resistance
earthing for the protective circuitry.
Thus the current loop can be operated
with a floating ground. This VSSC4
CL FG limits the surge voltage in an
analogue unearthed signal circuit
(e.g. a current loop).
VSSC4 SL
The basic principle of a binary current circuit
VARITECTOR SSC6
The VSSC4 SL is a two-stage
protective combination with a
suppressor diode for each stage from
the current path to PE. This VSSC4 SL
limits the surge voltage in an earthed
binary signal (e.g. for alert contacts).
The VSSC4 SL FG is used for nonearthed signal circuits.
VARITECTOR SSC4
2028840000
Lightning and surge protection
for control and instrumentation signals
VARITECTOR SSC 6AN
VARITECTOR SSC
The VSSC4 SL FG is a two-stage
protective combination with a
suppressor between the current paths
and common return wire. The gas
discharge tube to the PE provides
a high-resistance earthing for the
protective circuitry. Thus the protective
circuitry can be operated with a
floating earth. This VSSC4 SL FG limits
the surge voltage in a binary floating
signal circuit.
VSSC4 TAZ
The VSSC4 TAZ provides one-stage
protection with a quick-response
(<10 ps) suppressor diode (TAZ) for the
current path to PE. This VSSC4 TAZ
limits the surge voltage in a circuit
(e.g. for digital inputs). The TAZ is
available in voltages of 12 V, 24 V,
48 V and 60 V.
VSSC4 MOV
The VSSC4 MOV provides one-stage
protection with a varistor (MOV) for the
current path to PE. This VSSC4 MOV
limits the surge voltage in a circuit
(e.g. for solenoid valves). The thermally
monitored MOV is available in voltages
of 12 V, 24 V, 48 V, 60 V, 120 V,
150 V and 240 V.
240 V.
VSSC4 RC is the final protective
variant in the VSSC series. This variant
combines a thermally monitored
varistor and an RC combination. It
can be used for spark suppression
on inductive loads. The VSSC4 RC is
available in 24 V and 240 V.
VSSC4 GDT
The VSSC4 GDT provides one-stage
protection with a gas discharge tube
(GDT) for the current path to PE. This
VSSC4 GDT limits the surge voltage
in a circuit. This terminal is used

VSSC6 CL
The VSSC6 CL is a two-stage
protective combination that has a
suppressor diode between the current
paths. This VSSC6 CL limits the surge
voltage in an analogue signal circuit
(e.g. a current loop). The PE potential
can be provided on terminal point
3/6 by snapping the terminal on an
earthed DIN rail. This allows a shield
connection to be connected. This
version is also available as the
VSSC6 CL FG floating-ground
protective circuit.
The VSSC6 TR CL is built like the
VSSC6 CL and also has two isolators.
The 2.3-mm PS 2.3 (order number
018040000) can be plugged into the
Torx® screw head. The isolation makes
it possible to take measurements in
the field, in the electrical cabinet or via
the surge protection. This version is
also available as the VSSC6 TR CL FG
floating-ground protective circuit.
B
The VSSC6 SL LD is a two-stage
protective combination with a
suppressor between the current
paths and common return wire. This
VSSC6 SL limits the surge voltage
in two binary signal circuits. The
signal status for each signal circuit is
indicated by an LED.
The VSSC6 TR SL LD is built like the
VSSC6 L LD but also has two isolators.
The 2.3-mm plug uses the screws to
provide easy signal measurements.
This version is also available as the
VSSC6 TR SL FG floating-ground
protective circuit.
The VSSC6 MOV provides
one-stage protection with two
thermally monitored varistors (MOV)
between the current paths and
common return wire. This VSSC6 MOV
limits the surge voltage in two binary
signal circuits.
The VSSC6 TR LD MOV provides
one-stage protection with two
thermally monitored varistors (MOV)
between the current paths and

VSSC6 RS232
The VSSC6 RS232 is a two-stage
protective combination that has
suppressor diodes between the current
paths. This VSSC6 RS232 limits the
surge voltage in a signal circuit.
Black Material PA6.6 with UL94 V0 is
used for the VSSC4 and VSSC6 series
so that they are suitable for use in
many applications. They are suitable for
use in temperatures ranging from
-40 to +70 °C.
The VSSC series is used to protect
signal circuits. In order to achieve
a complete protective strategy for
the facility, the power feed must be
protected with Type II surge protection
(for example, by using the
VPU II series).
For existing lightning protection
facilities, Type I protection must be
used (for example, by using the VPU I
series). Type II protection (for example,
the VPU II) is sufficient when there is
no lightning protection facility.
Discharge capacity
Tested in compliance with standard
IEC 61643-21 for providing surge
protection in signalling networks with
voltage and current pulses. The VSSC
series has been tested to comply with
IEC 61643-21 and EN 61643-21.
Modules were tested with categories
C1, C2 and C3: with quick-rising edges
with up to 300 pulses. Category D1
describes high-power testing
(10/350 μs), so that the VSSC series
can be used in compliance with IEC
62305-4. The VSSC is colour-coded so
that it is easy to detect the voltage level
(or the signal location SL or CL).

VARITECTOR SSC 4AN
Lightning and surge protection
in terminal block design
The new and comprehensive surge protection family
for measurement and control technology in 6 mm
overall width
The interfaces in C&I applications must be protected against
surges, since coupling of surges on lines can interfere with
or destroy signal inputs. It is therefore necessary that C&I
devices be protected in their immediate vicinity. For this
purpose, VARITECTOR SSC, with its compact terminal-block
format, is ideal for this application. The protective circuits are
matched to the current loops and to binary signals.
The VARITECTOR SSC products are tested according to
the latest standards (IEC61643-21): They satisfy the safe
short-circuit mode in the event of overload by AC currents in
classes D1, C2 and C1. The products are ATEX-tested for use
in intrinsically safe circuits.
Easy to use
The clamping area of 0.5 mm² – 6 mm² is
covered with combined Torx®/Slot headed
screw and a tightening torque of 0.8 Nm.
Space-saving
Modular width of terminals just 6.2 mm for two
binary signals or per analogue signal.
B.94
2028840000
Large variety
A solution for every type of surge protection:
More than 100 variations: current loops and
binary signals for 5 V, 12 V, 24 V, 48 V and
60 V, with integrated components, e.g. varistors.

Quick identification
Large-area marking options: marking of devices
and single connections as well as colourcoded marking of the voltage levels for fast
identification in the switching cabinet.
Simple and safe
Simple installation and high safety through
direct PE contact when mounting on the
terminal rail, with a very high discharge current
of up to 20 kA.

MCZ OVP
Lightning and surge protection
for data interfaces
Weidmüller’s “MCZ OVP” surge protection for industrial
bus systems and data interfaces: Narrow surge-protection
terminals with tension-clamp connections for PROFIBUS,
Interbus, CAN, DeviceNet and LON™ – with no signal delay. The
Omega stainless steel spring used for DIN rail contact ensures
outstanding discharging characteristics that are consistent and
reliable.
Space-saving
The narrow 6-mm MCZ OVP surge protector is
installed simply and quickly due to its terminal
block design.
Quick to connect
Maintenance-free tension-clamp wire
connection: providing strong contact force and
quick wiring times. This ensures a more securely
clamped wire across the entire clamping area.

Narrow surge protection terminals with tension-clamp wire
connections for measurement and control systems
Weidmüller MCZ surge protection terminals are
characterised by their maximum protective function,
and a compact design of only 6 mm. The tension spring
connection and direct earthing via the terminal rail contact
results in time-savings during installation.
The MCZ OVP terminals are suitable for ­installing in the
tightest of places in automated process, ­industrial and
building services systems.
The different models
The three-stage surge protection terminals are fitted with
gas discharge tubes, varistors, suppression diodes (TAZ) and
decoupling inductors. Individual protective components such
as varistors and suppression diodes complement the range.
The MCZ OVP surge protection terminals are available with
rated voltages of 24, 48, 115 and 230 V. The response
time for the 3-stage MCZ OVP is typically 100 ps. The earth
­contact is produced by clipping the terminal to an earthed
­terminal rail. To guarantee a safe energy discharge of up to
10 kA (8/20 µs) via these terminals, the TS 35 rail must be
earthed.
EMC regulations require the terminal rail to be securely
screwed to an earthed mounting plate. Optimum protection
is achieved when the PE contact is made via a tension spring
terminal every 600 mm.
Attenuation chart MCZ OVP Filter
MCZ OVP HF is a two-stage protective combination with
a bridge circuit consisting of suppressor diodes. With this
circuitry, high transmission rates of up to 100 Mhz can be
reached in 100 Ohm systems.
The protective circuitry is particularly suitable for protecting
high-speed data transmission systems and high-speed
analogue systems.
MCZ OVP CL is a three-stage protective combination with
a suppression diode between the current paths. It limits the
­surge in analogue signal circuits, e.g. current loops.
MCZ OVP SL is a three-stage protective combination with
two suppression diodes, each from the signal line to earth. It
limits the surge in binary circuits, e.g. for actuators.
MCZ OVP CL FG is a three-stage protective combination
with a suppression diode between the current paths. It limits
the surge in analogue signal circuits. A high-resistance earth
connection is achieved with a gas discharge tube.
MCZ-OVP Filter-Terminals contain selected varistors,
­capacitors and series inductances. They form reliable
noise ­filters. Coupled interference in the kHz range is safely
­discharged to earth. For example, the signal inputs of a PLC,
which can be protected against interference voltages and RF
interference.

Differences between earthing and shielding
The terms “earthing” and “shielding” are classified according
to their relation to human safety or facility safety. The earth
is installed primarily to protect human life and for this reason
is referred to as the protective earth conductor. On the
other hand, shielding is used to ensure that the electrical
system functions properly. It also ensures electromagnetic
compatibility.
The illustration below shows how these two topics relate to
each other in application.
These main differences between the two terms influence the
electrical design and installation. Shielding is not designed
to transfer power, although leakage currents may flow on
them. A protective earth conductor, however, must be able
to briefly discharge a high fault current (IEC 60947-7-2).
The short-term current resistance of the PE connection must
be 120 A/mm² for the connected cross-section.
Different symbols are also used for
the two themes:
As shown in the picture below, the cable’s shielding is
connected to the earth potential so that the
shield’s current can be discharged. Depending on the
sensitivity of the facility, isolated areas of potential can
be created. However it is still typical to mix the areas, so
that the shielding is on a common equipotential earth.
This illustration shows how the number of shields and PE
conductors that need to be connected can increase quite
rapidly (in this case only one component is used). The
shielding and earthing systems must be planned carefully to
provide adequate safeguards for personnel and equipment.
The following sections describe the complexity and
uniqueness in more detail.

Earthing for shielded cables
Earthing for shielded cables
Electrical and electronic systems should be designed and
installed so that they are essentially protected against
electrical interference, so that they also function reliably in
the event of transient interference voltages.
Electrical interference is introduced into circuits in many
different ways. The most frequent cause is inductive
interference effects. However, conductive or capacitive
coupling plus electrical fields and other phenomena can also
cause interference voltages. In these cases high-frequency
voltage oscillations – the so-called transients – are very likely
the cause of the interference.
Shielded lines enhance interference immunity
The sources of interference voltages can never be eliminated
completely. Therefore, we have to take measures to deal
with their effects. Generally, it is true to say that the more
effectively we can keep interference voltages away or
discharge them from circuit elements, the smaller are their
disturbing effects. This can be done in many ways – with
differing degrees of ­effectiveness. One really effective
measure for protecting against inductive influences, i.e.
guaranteeing the electromagnetic compatibility, is to shield
the electric functional components at earth potential. One
way of doing this is to i­nstall components in metal, earthed
housings and to shield the connecting lines.
Generally, it is true to say that counteracting the interference
­effects of lines is feasible by laying the lines as far apart as
­possible, keeping the common return as short as practical,
or using twisted lines. A far better method of protection,
however, is to provide a continuous shield for all lines. This
is the most effective measure that can be taken against the
coupling together of interferences.
2028840000
The best form of shielding consists of a braided hose of
­individual wires made from a non-magnetic material (copper,
aluminium). The braiding should be sufficiently robust and as
solid as possible. Care must be taken with lines protected by
a foil shield because of the foil’s low mechanical strength
and low current-carrying capacity.
B
Correct use of shielded lines
Adding shielding to lines achieves the desired effect only
when they are properly designed and installed. Incorrect
earthing or the use of components that do not function
satisfactorily ­reduce the effect or even nullify it altogether. It
is not sufficient to connect the shielding to earth potential
at just any point b
­ ecause it could be the case that this earth
connection is ­inadequate for high frequencies. In addition,
we must also watch out for earth loops, the shielding must
be earthed over a large area, and the quality of the shield
bonding lines and earthing accessories is also important.
B.121
Lightning and surge protection
for control and instrumentation signals
Earthing for shielded cables
B
Shielding
In practice, the shield is often twisted and connected to
a terminal point. There is very high attenuation (voltage
drop) on these connections, especially for high-frequency
interference. Therefore this type of shielding should not
be used, even for short cable lengths. The cable shield is
practically negated and can, at best, be helpful for lowfrequency interference. We recommend a large, extensive
contact with the braided shield of the cable.
The following pictures show examples of use:
There are four main types of coupling:
• Galvanic coupling
• Capacitive coupling
• Inductive coupling
• Radiation coupling
Such interferences usually occur mixed together, but they
can be categorised as follows:
• Electromagnetic fields
• Ripple voltage (50 Hz)
•Lightning
• Interference pulses (current, voltage)
• Transient surge voltages
• Radio interference
• ESD (electrostatic)
•Burst
• Mains feedback
Shield connection via functional earth
The conductor “flow” is another detail for concern with the
shield contact. The temperature changes caused by the
current flow lead to changes in the wire’s diameter. A rigid
contact can therefore only be partially effective. A selfadjusting contact is what is really required. Weidmüller’s
clamping yoke products (KLBÜ) provide the perfect solution
for this challenge.

Effective shielding
It is important to remember that the shielding should not be
connected to the earth of the module connected, but rather
to the protective earth (PE). In the case of modules
mounted in an earthed, metal housing, the shielding must
be connected to this housing. If an earthed housing is not
available, the ­shielding must be connected to a separate
earth.
When laying earth connections to shields it must also always
be ensured that no earth loops are formed. The smaller the
earth loop, the lower is the risk of inducing interference
­voltages. Therefore, a true star arrangement is the best
answer.
The sketches below show general, feasible connections
­between shield and protective earth.
Connecting the shield at one end protects against ­
capacitive-coupled interference voltages.
System 1
System 2
Connecting the shield at both ends is suitable for protecting
against inductive-coupled interference fields.
System 1
2028840000
A high-resistance connection at one end of the shield is
recommended when trying to avoid the disadvantages of
forming an earth loop in the case of shields connected at
both ends.
System 1
B
System 2
On longer shielded lines, e.g. when a sensor has to be
routed to the control room, the potential difference between
the two ends should not be ignored. If a current-carrying
shield ­bonding line is used, it is possible to compensate for
the ­potential difference between the measuring point and
the ­control room by means of this shield. However, such
shield lines are relatively expensive and also complicated to
fabricate and install. Another possibility is to lay an additional
­equipotential bonding line between the measuring point and
the control room. The shield can then be connected at both
ends.
Yet another possibility is a high-resistance earth. The shield
is then connected to earth potential in the control room,
and at the measuring point connected to earth via a gas
discharge tube in a high-resistance arrangement. This solves
the ­problems of potential transfer and a 50 Hz hum.
Two gas discharge tubes must be installed for non-floating
measuring points. One connects the shield to earth and the
other to the non-floating measuring point. This prevents
­conductive coupling between the measuring circuit and the
earthed measuring point.

Summary
The earthing is an important factor affecting the reliable
­operation of electrical installations in the event of
interference effects. RF aspects must be taken into account.
Only the ­correct use of materials and well-thought-out circuit
design can bring success.

The supply and earth lines to protective modules should
be kept short in order to achieve optimum protection for
­equipment.
The fuses for the protective modules should be chosen
­depending on the rated current as well as on the type of line
and its route.
Mounting rail contact as earth in connection
for MCZ OVP
Installation position
The shielded signal lines should be connected to PE via
terminal clamps (Weidmüller KLBÜ). Unshielded lines should
be twisted. Neutral earthing is preferred. All the protective
modules belonging to one part of the system should have
neutral e
­ arthing. A through-connection of the earth line
should be ­avoided.
Protected and unprotected lines must be laid separately.
A common cable duct should be connected with metal
partitions.
Likewise, signal and power lines should be laid separately.
­Electrical isolation, e.g. with relay couplers or analogue
­converters, should be employed for installations involving
­several buildings. This avoids interference currents via minus,
PE or N.
The supply and earth lines to protective modules should
be kept short in order to achieve optimum protection for
equipment. Transmission paths should also be kept as short
as possible because the longer the line, the greater is the
chance that interference can affect the line. The inclusion of
­surge protection also increases the attenuation of the line
and t­ herefore changes the signal-to-noise ratio.
The protective modules are frequently installed at both ends
of the line.
It is important to ensure that protected and unprotected
lines are routed separately. In addition, there must be some
distance between power lines and data lines. A common
cable duct should be connected with metal partitions.
The protective modules should be mounted in a panel near
the entry point of the lines. Unprotected lines should not be
fed ­into parts of the system. Therefore, the lower level in the
panel should be used for the protective modules.
B.124
Contact to the rail is automatically established using the
snap-on attachment. The TS35 rail must be earthed in order
to ensure safe power discharging via the surge protection
elements of up to 20 kA (8/20 µs) and 2.5 kA (10/350 µs).
The DIN rail should be screwed onto the earthed mounting
plate to ensure EMC. It is also possible to contact the PE
every 60 cm / 24 inch using the tension-clamp terminal on
the MCZ OVP.

VARITECTOR SPC EX and ACT20X
Pluggable surge protection and a universal signal converter for C&I
signals in hazardous area applications
Intrinsically safe circuits to limit energy are used in hazardous areas. In these
circuits, the intrinsically safe signal converters with their galvanic isolation and
Ex approved surge arresters provide excellent protection for sensitive control
electronics.
Surge voltages on the field side of the measurement and control lines can damage
the facility. The VARITECTOR SPC EX can discharge surge voltages in hazardous
area applications (zone 0, 1 and 2). The pluggable arresters conform to the
requirements of the current standards with regards to Ex intrinsic safety.
They also comply with the IEC 61643-21 surge protection product standard and
are certified for protection classes D1, C2 and C3.
The ACT20X-HUI-SAO-LP offers an intrinsically safe input for standard DC signals,
temperature signals and resistance signals. It also isolates the Ex zone from the
safe area. The 12.5 mm wide module is powered via the 4 … 20 mA output.
The global ATEX, IECEx and cULus Ex approvals allow it to be used throughout
the world.
Space saving
The VSPC EX uses less space in the electrical
cabinet, with four binary or two analogue
signals in only 17.8 mm width.
Unlimited protection
The VSPC EX products are special, intrinsically
safe surge arresters. Low Li and Ci values mean
they are not relevant for the entire application's
proof of intrinsic safety.

VARITECTOR SPC EX
Weidmüller’s VARITECTOR SPC EX
pluggable surge protector is
remarkable for its combination of
extremely high protective functionality
and compact dimensions. It protects
intrinsically safe measurement and
control circuits. The size is made
possible by the selection of INSTA
dimensions, with a width of 17.8 mm
(1 TE). You save time on connections
because of the screw connection and
the indirect earthing contact via the
DIN rail. The VARITECTOR SPC series
is optimally designed for compact
installations in process automation,
industrial automation and building
automation. The two-stage surge
protection terminals are equipped with
gas discharge tubes, suppressor diodes
(TVS) and decoupling components.
IEC 62305 requires that a periodic
inspection of surge protection products
be conducted. The functionality of
all VARITECTOR SPC modules can
be tested using testing equipment
(such as the V-TEST) that is available
separately.
You can get our VARITECTOR SPC
surge protection series in the nominal
voltages of 5 V, 12 V and 24 V. The
product’s voltage level is colour-coded
on the pluggable arrester.
It can be snapped on an earthed DIN
for indirect earthing. The TS 35 must
be earthed in order to ensure safe
power discharging via the terminals
of up to 20 kA (8/20 µs) and 2.5 kA
(10/350 µs). The DIN rail must be
screwed onto the earthed mounting
plate to ensure EMC.
In order to optimise the protective
function, the PE contact should be
made every 60 cm / 24 inch using
the terminal on the VARITECTOR SPC
module.
A testing device, available as a
Weidmüller accessory, allows you
to test the protective element in
compliance with the IEC 62305-3
directive. Accessories also include
the EMC SET which provides a simple
method for creating the cable shield.
Overview of model types
Surge protection consists of a separate
plug-in VARITECTOR SPC EX
and a separate base
unit VARITECTOR SPC BASE.
ATEX
T
The VSPC EX series comes in a light
blue housing and is used to protect
electronics connected to intrinsically
safe circuits. The unearthed (floating
ground - FG) VARITECTOR SPCs have
negligible internal inductance and
capacitance.

Products for intrinsically safe
circuits
VSPC 1CL 12 V ATEX
and VSPC 1CL 24 V ATEX
This VSPC surge protector is used to
protect an intrinsically safe current
loop.
VSPC EX 1CL 5 V ATEX
This VSPC EX surge protector is
suitable for temperature signals which
goes in and out of the intrinsically safe
zone.
VSPC EX 1CL 12 V ATEX (Namur)
This VSPC EX surge protector is used
to protect a Namur sensor signal in an
intrinsically safe zone.
Colour coding
24 V
VSPC 1 CL PW
The pluggable components transfer
their coding to the BASE when they are
plugged in for the first time.
The voltage level is also marked with
coloured Dekafix on the VSPC EX
plug section. This gives you a better
overview within the electrical cabinet.
VSPC EX 1 CL 24 V/Power ATEX
This VARITECTOR SPC surge protector
protects an analogue signal and has an
intrinsically safe power supply which
is protected by a Type III end-device
protection mechanism.
All in one product it is suitable for an
intrinsically safe sensor, which also
requires an intrinsically safe power
supply.
Testing option
VSPC EX 2SL 12 V DC ATEX
VSPC EX 2SL 12 V AC ATEX
VSPC EX 2SL 24 V DC ATEX
These VSPC EX surge protection
modules are used for protecting two
intrinsically safe binary signals.
Because the modules are pluggable, it
is possible to test the VSPC EX using
the V-TEST testing device. The user
inserts the VSPC EX into the testing
device for testing. The result is then
shown on the display.

Markers
The VSPC BASE lower section can be
labelled with Dekafix 5 markers.
The VSPC pluggable modules are
colour coded with Dekafix 5 according
to their nominal voltage.
Installation
The VSPC EX series is used to protect
signal circuits. In order to achieve
a complete protective strategy for
the facility, the power feed must be
protected with Type II surge protection
(for example, by using the VPU II series).
For existing lightning protection
facilities, Type I protection must
be used (for example, by using the
VPU I series).
When there is no lightning protection
system, the Type II protection is
sufficient (such as the VPU II).
Monitoring
IEC 62305-3 requires testing and
maintenance for lightning protection
systems.

VARITECTOR SSC EX
Lightning and surge protection for intrinsically safe circuits
in the explosion hazard area
When used in intrinsically safe circuits within EX zones 2 to 0,
the VARITECTOR SSC can reliably protect measurement and
control signals from lightning and surge voltages.
Lightning and surge voltages – whether direct at the
facilities, near field or far field – can cause signal interference
or even destroy connected devices. They could even lead
to an explosion within hazardous areas applications. The
VARITECTOR SSC EX product line, with a width of 12.4 mm,
offers protection against these risks. These products comply
with the new IEC 61643-21 standard. They fulfil the “overstress mode” described. They are also in compliance with
the most current ATEX Standard, in EN 60079. Lightning
and surge protection components are versatile and simple
to use since they feature direct contact to the PE, many
marking and diagnostic options, and an easily disconnected
signal path. The VARITECTOR SSC EX takes advantages
of these features so that it can easily be used in place of a
transfer terminal.
Space-saving
A compact installation is possible because of
the VSSC EX module's terminal design and
12.4 mm alignment width.
No limitations when used in the EX zone
The EX zone approval provides the proof that the
VSSC EX can be used in all EX zones (from zone
2 to zone 0) for dust or gas.

B
Complete, standard compliant protection
The VSSC EX prevents compensation currents
ia the PE. It also complies with the over stress
mode of the IEC 61643-21 standard.
No proof of intrinsic safety
Because of the negligible Li and Ci values, no
special proof is required for EX zone use.

12.4-mm-wide lightning and surge
protection for measurement and
control signals in the Ex zone
When used in intrinsically safe
circuits within Ex zones 2 to 0, the
VARITECTOR SSC can reliably protect
measurement and control signals from
lightning and surge voltages.
Lightning and surge voltages – coupled
from the field side to machines and
facilities – can cause signal interference
or even destroy connected devices.
They could even lead to an explosion
within high-risk Ex-zone applications.
The new VARITECTOR SSC EX product
line, with a width of 12.4 mm, offers
protection against these risks. These
products comply with the new
IEC 61643-21:2008 standard.
They fulfil the “over-stress mode”
described. They also meet the latest
ATEX standards, EN 60079. These
lightning and surge components are a
versatile and efficient solution because
they feature a direct PE contact,
extensive labelling and diagnostic
options, and easy separation of the
signal paths. The VARITECTOR SSC EX
takes advantage of these features so
that it can easily be used in place of a
transfer terminal.

internal inductance and capacitance.
Products for intrinsically safe
circuits
VSSC4 CL FG EX are used to protect
an intrinsically safe current loop.
VSSC4 SL FG EX are used to protect
intrinsically safe binary signal
circuits (such as alarm contacts).
VSSC4 GDT 24Vuc 20kA EX can
be used to provide high-resistance
earthing for shields
VSSC6 TR CL 24Vuc EX are used
to protect an intrinsically safe current
loop. Measurements can be taken in
the current loop by simply opening the
isolator. A test plug can be inserted in
the 2.3-mm test socket (built into the
head of the Torx® screws).
VSSC6 RS485 PA EX is used to
protect the intrinsically safe
PROFIBUS-DP.
