equipment and property from dangerous line-toground and shock hazard currents.
US applications include ground fault protection
of equipment (GFPE), especially when high
distributed capacitance or other leakages cause
excessive nuisance trips at lower fault currents.

Altech’s manual motor controller is UL listed. The UL Listed mark on the
MCB is the manufacturer’s representation that samples of the complete
product have been tested by UL to be used for most common industrial
applications. This superior UL mark allows for field installation without the
need for UL investigation.
A competitor’s UL recognized component mark on the MCB means that
the component alone meets the requirements for a limited, specific use.
These MCBs are not intended for separate installation in the field, they
are intended for use as a component of complete equipment submitted to
UL for investigation.

Application Examples:
High inrush motors, transformers,
power supplies, heaters and reactive
loads. Relatively long thermal trip
delay and very high magnetic trip
point.
Prototype testing is recommended in
motor applications where the relatively
long thermal trip delay may not
provide adequate motor overload
protection. Motor-integral overload
protectors are recommended, with the
V-EA-D providing disconnect, backup
thermal protection and additional short
circuit and energy let-through
protection.

Application Examples:
High efficiency motors, which have
exceedingly high inrush currents.
Relatively short thermal trip delays
and very high magnetic trip points.
Prototype testing is recommended.
The V-EA-E is the result of continuous
research and improvement of our Gand D-Trip circuit breakers. It
combines the short thermal trip delay
of the G-Trip and an even higher
magnetic trip point than the D-Trip.
Therefore, the V-EA-E provides
adequate motor overload and short
circuit protection.

Resistances listed are “hot” values, as
opposed to cold start values. Operating
voltage drop across the V-EA and power
loss per pole can be approximated with
basic formulas:
VDROP
= IOPERATING x RTABLE
PLOSS P/P = I2OPERATING x RTABLE
Voltage drops should be reviewed when
V-EAs with high internal resistance are
used (e.g., load voltage minimums).
Power loss should be reviewed when
V-EAs with high rated currents are used
(e.g., enclosure heating).
The listed V-EA internal resistance values
should not be used in calculations of
available short-circuit current downstream
of the V-EA. The dynamic impedance of
the V-EA under short-circuit conditions
can vary significantly from internal
resistance values in normal operation.

The thermal trip is not affected by the frequency of the line
current. The magnetic trip is within the trip zone of the
characteristic curve for frequencies from 16 2/3 to 60Hz. At
lower and higher frequencies, the magnetic trip will be delayed
longer than indicated by the characteristic curve, roughly as
follows:
At 100Hz:
At 200Hz:
At 400Hz:
At DC:
Mag. Trip Current = 1.1 x curve current
Mag. Trip Current = 1.2 x curve current
Mag. Trip Current = 1.4 x curve current
Mag. Trip Current = 1.5 x curve current
For example, at 16 2/3 - 60 Hz the magnetic trip zone for the “G”
characteristic is 8 to 10 times the rated current of the specific
V-EA (i.e., hold for at least 100ms at 8 x RC, trip in less than
100ms at 10 x RC). With a 400Hz current, a magnetic trip at 10
x RC would be greatly delayed (thermal would likely trip first), as
the magnetic trip zone is now 11.2 to 14 x RC. If a quicker
magnetic trip is required with 400Hz, the “B” or “C” characteristic
should be considered.

INSTALLATION RECOMMENDATIONS
INTRODUCTION
EASY REMOVAL
The V-EA* easily snaps onto a readily available, international
standard 35mm DIN Rail. Mounting can be in any position from
full horizontal to full vertical without affecting performance.
All housings are the same size regardless of rated current,
simplifying layout and modifications.
Line power feed can be to either top or bottom terminals. This
provides flexibility to power distribution enclosure entry (top,
bottom, sides) and internal raceway runs (e.g., power in one
horizontal raceway can feed both the row above and the row
below).
Minimal free space is required to remove or replace the V-EAs,
and with standard housing and terminal sizes, ratings can be
changed or multi-poles can replace multi-single pole or viceversa. To obtain the highest density mounting arrangement
without serious problems from heat build-up, see “Temperature
Correction Curve” (page 22).
Removal, One Pole
1. Insert tip of 4mm or less straight blade screwdriver into the
slot of the metal retaining clip.
2. Brace the shank of the screwdriver against the terminal
side of the V-EA* and gently lever the clip away from the
DIN rail.
3. When the clip moves out, continue rotating screwdriver
and V-EA* up and off of the bottom of the DIN rail lip.
4. Grasp V-EA* and lift upwards to disengage from the top
lip of the rail, then remove.
Altech and our distributors are pleased to quote custom rail
assemblies. Multi-function assemblies can include cut-to-order
DIN Rail, mounted V-EA and MA circuit breakers, FI Earth
Leakage breakers, lightning/surge protectors, interface modules
(cable fan-out, relays, I/O, power supply, etc.), terminal blocks
with marking tags, and other control components to meet your
specifications. Order assemblies with only one part number or
even your drawing number.
DIN Rail Information
Mounting rails are internationally standardized and are available
in several sizes with or without perforations. Zinc-plated yellow
chromated steel is standard. Copper and aluminum DIN Rails
are also available. Please contact Altech for your DIN Rail
needs.

ALTECH/SPELSBERG EK/AK NONMETALLIC ENCLOSURES FOR MCBS
NOTE 1: For totally enclosing the V-EA, the
minimum interior depth of the enclosure is
70mm plus DIN Rail depth (7.5 or 15mm) plus
any rail mounting stand-off depth.
NOTE 2: Fork lugs with a thickness up to
3mm can be inserted in the lower terminals
under the head of the captive M5 (i.e. 5mm
diameter to outside of threads) terminal screw.
NOTE 3A: The V-EA’s raised face is sized to
fit through standard European enclosure cutouts, which allow sight and operation of the
trip/reset handle but keep all wiring covered.
As shown in Fig. 1, Altech/Spelsberg AK/EK
nonmetallic enclosures are ready-made for
this attractive and efficient packaging approach.
NOTE 3B: The V-EA was successfully shortcircuit tested in TYPE 1 metal enclosures with
the V-EA face extending through a 46mm cutout in the cover. Typical applications include:
• V-EA on 35mm wide by 15mm deep DIN
Rail, mounted to back wall of a 3 inch deep
enclosure with no back panel.
• V-EA on 35mm wide by 7.5mm deep DIN
Rail, mounted to the back panel of a 3 inch
deep enclosure with panel.

MA Three Phase
Adjustable Trip
Miniature Circuit Breakers/
Manual Motor Controllers
The MA was designed to handle the high
inrush loads of 3 phase transformers, power
supplies, motors, etc. The MA protects wiring
and equipment from damage caused by the
three major classes of over-current, yet
greatly reduces the number of nuisance trips
in high starting and inrush current circuits.
An IEC device with excellent ratings under a
UL listing at 480Y/277V (including group
ratings) and at 500V under international
standards, the Altech/ Sursum MA provides
short and long term cost effective circuit
protection for USA and/or export
applications. The short term advantages
include: (1) adjustable thermal trip allows
finalization of initial designs before
procurement of the load equipment is
complete; (2) snap-on mounting for readily
available, internationally standardized DIN
Rail saves panel layout design time as well
as installation and change labor; (3) large
cage-clamp terminals with screws suitable to
power screwdrivers, simplifies and speeds
wiring; (4) convenient switched disconnect
during factory testing and/or initial start-up
saves time and aggravation. The key long
term advantage is customer satisfaction and
proven over-current protection of wiring and
equipment (and the lack of rework/repair
costs).

FI Earth Leakage
Circuit Breakers
FI compact Earth Leakage Circuit
Breakers detect and interrupt earth
(ground) faults. They are VDE
approved for the European system
of protecting people, animals,
equipment and property from
dangerous line-to-ground and shock
hazard currents.
US applications include ground-fault
protection of equipment (GFPE)
using the 10mA and 30mA fault
current ratings, especially when high
distributed capacitance or other
leakages cause excessive nuisance
trips at lower fault currents.
Applications for the 300mA rating are
equipment protection and fire
prevention, limiting the energy of a
fault to less than the minimum
ignition energy for many materials.

Temperature Range
Environmental Information marked with “Snowflake” approval for -25°C to 40°C (-13°F to 104°F) ambient
temperature. (Temperature effect on RC: for every 10°C temperature rise above 40°C decrease RC by 7%.)
Fluctuating Climate Conditions
To maximum 45°C, 95% relative humidity.
Electrical Shock Protection
Uninsulated electrically live parts within 30mm of the operating handle are “finger safe” (terminal screw
heads) and uninsulated live parts within 100mm of the operating handle are “back-of-hand safe” (terminals).
Impact/Shock Protection
15g with impact force half-cycle sinusoidal and 11ms duration, 18 impacts total with 6 on each principal axis
(3 impacts each face). FI is DIN Rail mounted during the test, and electrically loaded with 25% of Fault RC.
Successful testing required no trip during the test, no damage and no loosened parts.
Vibration/Seismic Resistance
5g, at frequency of 55Hz to 2,000Hz, applied for 35 ± 5 minutes along each of the three principal axes, plus
5 minutes of application at every established critical resonant frequency. FI is DIN Rail mounted during the
test, and loaded with 25% Fault RC. To pass, the FI did not trip at 25% Fault RC, but did trip between each
of the principal axis tests when the fault current was raised to 125% Fault RC, and there was no damage
and no loosened parts. Suitable for machinery and mobile vehicle applications.
Housing Class
Ingress Protection (IP) Class 40; internal working components and live parts (excluding terminals) are
protected against ingress of solid objects greater than 1mm diameter (class 4-), but have no protection from
ingress of water (class-0).
Non-Sinusoidal Fault
The FI is tested and approval stamped for tripping sensitivity to non-sinusoidal fault currents, which become
zero or almost zero within one cycle of the line frequency. Waveforms and allowed trip-current ranges are as
follows:
1.
AC Sinusoidal Fault - 0.5-1.0 times Fault RC
2a.
Pulsating DC Fault;
Positive and Negative Half-Waves - 0.35-1.4 times Fault RC
Phased Half-Wave, 90° - 0.25-1.4 times Fault RC
Phased Half-Wave, 135° - 0.11-1.4 times Fault RC
2b.
3.
Insulation Category
Pulsating DC on 6mA
DC (continuous) Base - Max. 1.4 times Fault RC + 6mA
At VDE rated voltage, suitable for Class C environments with relatively high dust and moisture levels and
little HVAC control, e.g., industrial, commercial, agricultural; on machine tools, hoists, warehouse equipment,
etc.; in boiler rooms, unheated storage, covered shipping/receiving, open workshops, etc.

tripping latch pins of the V-EA or MA to
which they are attached, reliably producing trips at the drop-out voltage and
preventing resetting when less than 85%
line voltage is present. The Undervoltage
Trip is provided with at least 6-inch
pigtails of stranded fixture wire for hookup to the V-EA or MA line terminals.
• Reset-Hold Voltage = 0.85 x Ve
