Introduction
Standard MCC
tiastar MCC
Motor Control Centers (MCC) have come a long way since they were introduced in 1937
as a way to save floor space by placing several starters in a single cabinet. Ideally, the
best-of the-best must also save installation time and money.
Siemens has an installed base of Motor Control Centers dating back to 1964. Our
Siemens tiastar MCCs are designed as self-contained modular units which meets UL and
NEMA standards. They come with rear-mounted, self-aligning copper stabs that firmly
grasp onto the bus. Brackets guide the placement of units, further assuring positive
engagement with the bus. From 22mm to 30mm pilot devices, from direct starters to
world-class drives, the Siemens tiastar MCC has many features and options to meet your
specific needs.

Arc Resistant MCC
The Type 2 Arc Resistant low voltage motor control center is a new product offering that
was tested in accordance to IEEE C37.20.7, which contains and channels internal arcing
fault incident energy. It provides an additional degree of protection to the personnel
performing normal operating duties in close proximity to the equipment while the
equipment is operating under normal conditions. Type 2 accessibility means the MCC
protects the operator in front, back and sides of the equipment.
The Arc Resistant MCC is a state-of-art overarching technology. This means one can get
an Arc Resistant MCC that can have various Smart components with communications,
and/or High Density Compact Units.

Altitude Ratings
Siemens tiastar
Motor Control
Centers are
designed and built
to operate up to
2000 meters above
sea level (6,600 ft)
without any
modifications.
Altitude (m)
Motor control centers are often installed in applications exceeding 1000 meters (3300 ft)
above sea level. Due to the lower air density and heat transfer capacity at elevated
altitudes, the physical properties such as dielectric strength, load capacity of the motor
control centers, conductors and motors, as well as the tripping characteristics of thermal
relays may require modification to reflect these changes due to altitude. Paschen’s Law
describes the breakdown voltage of parallel plates in a gas, as a function of pressure and
gap distance. In other words, at lower pressure (higher altitudes) it takes less voltage to
cross a given distance increasing the chance for electrical arcs. To compensate for this, it
is recommended that the operational voltage be de-rated for altitudes exceeding 2,000
meters according to Paschen’s law. In addition, the rated thermal current should also be
reduced because of the decreased thermal efficiency of lower density (high altitude) air.
Siemens tiastar Motor Control Centers are designed and built to operate up to 2000
meters above sea level (6,600 ft) without any modifications. Siemens MCC components
are designed and manufactured to provide excellent insulation and arc flash protection
for bus components, in addition to having high thermal efficiency. Using creative design
and engineering, Siemens MCC’s can operate safely and reliably at altitudes up to 5,000
meters above sea level.

Structure & Bussing
NEMA Enclosure Types
Enclosure
Types
Indoor or
Outdoor
NEMA 1
Indoor
Description
This enclosure is primarily to prevent accidental contact by personnel with the enclosed
equipment and for protection against falling dirt. NEMA 12 reset and handle
mechanisms are standard for all enclosures.
This enclosure has the same use as NEMA 1 except the front of the enclosure is
gasketed.
NEMA 1A
Indoor
The parts that are gasketed include: Unit separator angles, Right hand side of front of
units, Bottom horizontal cross ties, Lip on top plate, Handle mechanism, and Bottom
horizontal wireway cover plate. The whole front of structure is gasketed, except the
hinged side of door.
This design is NEMA 1A front with a drip shield mounted on top of the enclosure.
NEMA 2
Indoor
This enclosure is to protect equipment against falling noncorrosive liquids and dirt. It
prevents the entrance of dripping liquid at a higher level than the lowest live part within
the enclosure. The drip shield completely covers the top and extends 3” over the front
and 1 1/2” over the sides of the basic structure. On front-only MCC’s, the drip shield is
flush to the rear. The drip shield is angled from front to rear and not flush with the top
of the MCC. The drip shield mounts on the top of the structure.
This enclosure is intended for indoor use in areas where fibers, lint, dust, dirt, and light
splashing are prevalent. The NEMA Type 12 enclosure will provide a greater degree of
protection than a NEMA 1A enclosure.
NEMA 12
NEMA 3R
Indoor
Outdoor
(Non
walk-in)
The following additional parts are gasketed: Hinged side of doors, Pilot device panel, Top
plates, Wireway end-covers, and Rear plates. Because of the divider side sheet
assemblies, there is no gap between sections, allowing for much greater dust resistance.
In addition, interconnection holes in the side sheet assemblies are sealed. Bottom plates
are included when NEMA 12 is specified.
This enclosure will prevent entrance of rain at a level higher than the lowest live part.
The enclosure has provision for locking and drainage. This NEMA 3R enclosure entirely
surrounds the motor control center for outdoor operation. Each non walk-in enclosure
has a floor and a slanted roof. All doors are louvered and screened to promote air
circulation and keep out pests. Motor control units can be racked in positive stop/test
position with the outer enclosure doors closed.
Rigid steel construction permits use from two sections up to any reasonable number of
sections. Stainless steel hinge pins and door stops are standard. Pressure Sensitive
Adhesive (PSA) Closed Cell Sponge Rubber door gasket forms a tight seal to keep the
elements out. Space heaters, fluorescent lights, fans, filters, blowers, and convenience
outlets are available as options. NEMA 3R enclosures are designed to accommodate
bottom cable entry and exit only. The enclosures are not intended to provide protection
against conditions such as dust, snow, or sleet (ice).
Attention: Variable Frequency Drives require special consideration, see units chapter VFD section for further details.
21
Structure & Bussing
Paint and MCC Finish
The motor control finish is an
electrostatically applied TGIC-free polyester
powder, applied both manually and
automatically in an environmentally
controlled clean room, cured at 400°F
for 20 minutes. All painted parts undergo
a five-stage preparation process that
includes an alkaline wash, water rinse,
iron phosphate wash, water rinse and a
non-chrome sealer. The minimum film
thickness on external surfaces is 2.0 Mils
and the finish passes a 600-hour salt spray
test per ASTM B117-94 definitions.
ANSI 61 Light Gray is the standard exterior
color. Unit backplates and the rear of the
vertical wireway are painted white for
improved visibility.

Structure Design and Options
Sections
Heavy 14 gauge steel side sheet assemblies
are used for supporting the structure
without additional bracing. The front of
each side frame has a 180° bend to provide
additional rigidity and a smooth edge.
Cross channels tie the side frames together.
A common sheet is used to provide
isolation between adjacent sections. A
shipping split will have two outer side
sheet assemblies and an inside divider side
sheet assembly between sections.
Mounting Sills
Full-length mounting sills are standard for
each shipping split. The sills are 3” wide by
1 1/8” high and constructed of 7 gauge
steel. They have four holes per section for
use with 1/2” (max.) anchor bolts. The sills
add additional structural rigidity. The
mounting sills are an integral part of the
structure and should not be removed.

Lifting Angle
A 7 gauge lifting angle is supplied with
every shipping split regardless of length.
The lifting angles are mounted atop the
MCC structure.
Side Sheets
Side sheet assemblies on 20” deep units
provide a 40.5 square inch wireway
opening at the top and a 46 square inch
wireway opening at the bottom to
facilitate routing wires through the
horizontal wireways between adjoining
sections. 15” deep units provide a 40.5
square inch wireway opening at the top
and a 30 square inch wireway opening at
the bottom.

Back-to-Back and Double Deep
MCC Options
Usually MCCs are front-mounted. However,
for the customers who want to save space
and cost, we offer our standard 21“ deep
back-to-back MCC design. We are the only
manufacturer in the market that offers 21”
deep back-to-back design with common
horizontal and vertical buses.
For customers that would like to have
back-to-back configuration but with
separate horizontal and separate vertical
busses for both the front and rear, double
deep MCCs are available with depths of
31" and 41".
Pull Box (Top Hat) Options
Pull boxes are generally used to provide
increased conduit mounting space and
additional cable bending space for
incoming main feeds instead of bus duct
connections. This type of pull box assembly
is referred to as a “top hat.” Top hats are
shipped 12”, 18”, or 24” high; 20” or 30”
wide; 15" or 20" deep for customer field
installation on top of MCCs.
Each pull box has an open bottom with

rear flange. After removing the top lifting
angle and front conduit cover from the
MCC, the pull box can be bolted to pretapped holes. The pull box has front, top,

that may require it. 30” and wider
structures may have horizontal bus, but are
not supplied with vertical bus. 30” wide
structures are available in 15” or 20” deep
design and line up with standard 20” wide
sections. 30” sections have full-width
doors, while wider sections have two
interposing doors. Dimensions for other
special equipment such as transfer

Structure & Bussing
Bus Selection and Options
For additional strength, the horizontal bus, vertical bus, bus support angles, and bus
bracing insulators form one unified assembly.
Horizontal Bus
The horizontal bus is a means of tapping
power for distribution to the various units
within a section. Siemens tiastar MCC’s
horizontal bus is always located on the top
of the vertical section and never located
behind unit space, allowing for easy
maintenance and serviceability.

Vertical Bus (cont)
Vertical buses are available in two designs:
1) Isolated – Isolated vertical bus design is
grounded sheet steel with stab
openings and is the standard for frontonly structures with 42kA or 65kA bus
bracing.The vertical bus bars in this
design are not physically insulated
phase-to-phase.
2) Insulated and Isolated – An optional
insulated and isolated vertical bus
design which prevents arcing faults
from propagating is available for front
only 42kA and 65kA bus bracing. The
isolated and insulated vertical bus
design is standard for 100kA bus
bracing and all back-to-back structures.
Figure 12. Isolated vertical bus
Figure 13. Insulated and Isolated Vertical Bus
Auto Shutter (optional) mechanism
automatically opens and closes to allow
insertion or removal of units. It prevents
inadvertent contact of the vertical bus;
thus, lowering the risk to personnel. Auto
shutters are available on vertical isolated/
insulated busses, however they are a
standard on arc resistant MCCs. It is
important to point out that the shutter
mounting holes are not in the standard bus
assembly and cannot be duplicated in the
field. Therefore, retrofitting automatic
shutters to MCC’s that do not have them is
not possible.

Structure & Bussing
Bus Selection and Options
Ground Bus
A standard horizontal ground bus is typically mounted in the bottom 6” of the structure.
An optional copper 1/4” x 1” vertical ground bus can be connected to the horizontal
ground bus. When a combination motor control unit is inserted into the MCC, the
optional vertical ground bus is engaged before the vertical power bus. The vertical
ground bus provides a means of assuring the plug-in unit is solidly grounded before the
power stabs are engaged and remains grounded until the power stabs are disengaged.
When vertical ground bus is specified on
back-to-back structures, vertical and
horizontal ground bus must be supplied in
the front and rear of each section.
The ground bus may be located in the
top or bottom front of 15” or 20” deep
MCCs or the top or bottom rear of backto-back structures under most situations.
A ground lug is supplied on one end of
the ground bus as standard or can be
optionally added to both ends. If not
otherwise specified, the lug will be
located in the incoming line section.

Neutral Bus
A neutral connection is generally required for 3 phase 4 wire systems. A neutral pad is
usually mounted in the incoming section only. Optionally, a neutral bus running the full
length of the line-up can be provided. When full length neutral bus is specified, the
neutral bus must be located in the bottom front of the MCC structure. Full length neutral
bus requires that the ground bus be mounted in the top of the structure. In general,
neutral bus capacity is sized at 1/2 main bus capacity. A two hole lug is supplied as
standard when a service entrance label is not required. For service entry, a neutral lug
and a bonding lug are supplied. All lugs used for ground or neutral are CU/AL type.

Figure 50. 1200A, 1600A Neutral Bus Connection
A combination starter is the grouping of a motor starter with a fuse or circuit breaker
disconnect. Plug-in units in a structure are connected to the vertical bus by a stab
assembly on the back of the unit. The stab assembly is then wired to a disconnect device
inside the plug-in unit. Power then flows through the circuit breaker, through the motor
starter, and ultimately to the motor.

Stabs
The power stabs engage the vertical power distribution bus when the units are installed
in the structure. Plug-in tin plated copper (standard) unit stab assemblies include selfaligning stab clips with spring steel backup springs. Wires from the stab clips to the lineside of the circuit breaker or disconnect switch are contained in the stab housing and are
isolated phase-to-phase until the wires enter the MCC.

Reduced Voltage Soft-Starter
(RVSS) Units
Siemens soft-start controllers and starters incorporate the latest in solid-state technology
to provide precise control in the starting of AC induction motors. Solid state reduced
voltage starting allows motor voltage to be gradually applied, reducing potentially
damaging high inrush currents and starting torques. These controls are easy to set up,
operate, troubleshoot and repair. They are fully adjustable for many applications and
with voltage ramp capability, can handle varying loads. Soft-start controllers can lower
operating costs by reducing downtime due to equipment maintenance and repair; and
minimize product and drive system damage caused by hard physical starts or stops.
Siemens Soft-Start controllers with the energy saving feature conserve energy during
lightly loaded conditions by reducing the motor voltage and current
Overview
The advantages of the SIRIUS soft starters at a glance:
n Soft starting and soft stop
n Stepless starting
n Reduction of current peaks
n Avoidance of mains voltage fluctuations during starting
n Reduced load on the power supply network
n Reduction of the mechanical load in the operating mechanism
n Considerable space savings and reduced wiring compared with mechanical reduced
voltage starters
n Maintenance-free switching
n Fits perfectly in the SIRIUS modular System
57
Units
SIRIUS 3RW40
SIRIUS 3RW40 soft starters include soft start and soft stop, and internal bypass. At the
same time they come with additional functions, i.e. selectable solid-state motor
overload, intrinsic device protection and adjustable current limiting, as well as a new
patented two-phase control method (Polarity Balancing) that is unique in this rating
range.
SIRIUS 3RW40 soft starters are part of the SIRIUS modular system. This results in
advantages such as identical sizes and a uniform connection system. Thanks to their
particularly compact design, SIRIUS 3RW40 soft starters are only half as big as
comparable wye-delta starters. Hence they can be mounted in compact space
requirements in the control cabinet. Configuring and installation are carried out quickly
and easily thanks to the 3-wire connection.
SIRIUS 3RW40 for three-phase motors Soft starters rated up to 300 Hp (at 460 V) for
standard applications in three phase power systems. Extremely small sizes, low power
losses and simple commissioning are just three of the many advantages of the SIRIUS
3RW40 soft starters.
Application areas:
n Fans
n Pumps
n Building/construction machines
n Presses
n Escalators
n Transport systems
n Air conditioning systems
n Ventilators
n Assembly lines
n Operating mechanisms

Units
SIRIUS 3RW44
In addition to soft starting and soft stopping, the solid-state SIRIUS 3RW44 soft starters
provide numerous functions for higher-level requirements. They cover a rating range up
to 900Hp at 460 V in the inline circuit. The SIRIUS 3RW44 soft starters are characterized
by a compact design for space-saving and clearly arranged control cabinet layouts. For
optimized motor starting and stopping, the innovative SIRIUS 3RW44 soft starters are an
attractive alternative with considerable savings potential compared to applications with a
frequency converter.
The new torque control and adjustable current limiting enable these high feature soft
starters to be used in nearly every conceivable task. They reliably mitigate the sudden
torque applications and current peaks during motor starting and stopping. This creates
savings potential when calculating the size of the control gear and when servicing the
machinery installed.
Be it for inline circuits or inside delta circuits – the SIRIUS 3RW44 soft starter offers
savings especially in terms of size and equipment costs. Combinations of various
starting, operating and ramp-down possibilities ensure an optimum adaptation to the
application specific requirements. Operating and commissioning can be performed by
means of the user-friendly keypad and a menu prompted, multi-line graphic display with
background lighting. The optimized motor ramp-up and ramp down can be effected by
means of just a few settings with a previously selected language. Four-key operation and
plain-text displays for each menu point guarantee full clarity at every moment of the
parameterization and operation.

Pollution Degree Ratings according to UL61800-5-1
MCCs containing VFDs should be installed in a Pollution Degree 2 environment in
accordance with UL61800-5-1. If an MCC with VFD is to be placed in a Pollution
Degree 3 or higher environment, a NEMA12 rated MCC should be installed.
Pollution
Degree
Description
1
No pollution or only dry, non-conductive pollution occurs. The pollution
has no influence.
2
Normally, only non-conductive pollution occurs. Occasionally, however, a
temporary conductivity caused by condensation is to be expected, when
the VFD is out of operation.
3
Conductive pollution or dry non-conductive pollution occurs, which
becomes conductive due to condensation, which is to be expected.
4
The pollution generates persistent conductivity caused, for example by
conductive dust or rain or snow.

SIMOCODE
Smart MCC uses SIMOCODE in the units to give the customer a true motor management
system. SIMOCODE pro is the flexible and modular motor control system for low-voltage
motors. It can easily and directly be connected to automation systems via PROFIBUS and
covers all functional requirements between the motor starter and the automation system
– including the fail-safe disconnection of motors. Further, SIMOCODE pro combines in
just one compact system all required protection, monitoring, safety and control
functions. The motor management system thus helps you to increase the process control
quality and reduce costs at the same time – from planning through installation right to
operation or service of a plant or system. In the MCCs, SIMOCODE pro C and SIMCODE
pro V are available.
Benefits from SIMOCODE pro:
n Simple configuration
n Protects your flexibility with the aid of optional expansion modules
n Gain transparency throughout your system with extensive data provision
SIMOCODE pro motor management is structured in functionally graded series:
n SIMOCODE pro C, as a compact system for direct-on-line starters and reversing
starters or the actuation of a circuit breaker with PROFIBUS-interface
n SIMOCODE pro V, as a variable system with all control functions and with the
possibility of expanding the inputs, outputs and other functions of the system using
expansion modules.

Pull-Apart Terminal Blocks
Pull-Apart terminal blocks pull apart and interlock mechanically, providing a terminal
block assembly in which individual groups are free to move to permit electrical
separation while remaining coupled mechanically to the series.
Clamping the wire between a tang and a collar provides the following advantages:
n No twisted off strands.
n A constant locking torque keeps screws in position.
n Hardened stainless steel clamping collar eliminates stripped thread problems.
n Terminal blocks are also available with screw type terminals for ring tongue lugs.
Stationary Terminal Blocks
Stationary terminal blocks are available. They have the same features as Pull-Apart,
except they remain fixed and do not separate.

Type C Wiring Terminal Blocks
Type C wiring uses stationary type terminal blocks. Their standard location is in the top 12” horizontal
wireway.
C terminals may also be located in the bottom 6” horizontal wireway. Three rows of terminals for control
and load may be mounted at the top. Space is available for 42 terminals per row for control and load. For
each unit size 2, reduce 3 terminals per unit, due to larger load blocks. For each unit size 3, reduce 6 per
unit. The bottom wireway is limited to one row of terminals only. C terminals cannot be located in the
same area as incoming lines. C terminals for a section with incoming lines, whether connected to main
lugs or main disconnect, will be located in an adjacent section. C terminals will be restricted to two rows in
a section with a print pocket. Ground or neutral bus should not be located in the same area as C terminals
because of restricted conduit room and the number of C terminals that can be mounted.

Metering Units
Advanced power monitoring devices are available for Siemens MCCs including SENTRON
PAC3100, SENTRON PAC3200, and SENTRON PAC4200. Siemens line of power meters
provides market leading technology for power quality measurement. These products
continually change to meet growing needs for power quality and energy monitoring.
The PAC3100 and PAC3200 are powerful compact power monitoring devices that are
suitable for use in industrial, government and commercial applications, where basic
metering and energy monitoring is required. The meter may be used as a stand alone
device monitoring over 25 (PAC3100) and over 50 (PAC3200) parameters or as part of an
industrial control, building automation or global power monitoring system. Metering and
monitoring applications range from simple analog volt and amp meter replacements to
stand-alone sub-billing or cost allocation installation (PAC3200 offers this with multiple
tariffs).
PAC3100
The PAC3100 has many features not usually found in this price class of meters. A large
graphical display supports multiple languages and easy to use menus that can be used to
set up the meter. The meter also has built in Modbus RTU communications via a RS485
interface. The meter comes standard with two digital inputs and outputs. One output is
suitable for pulse output for export/import real and reactive energy. The other output is
controllable from an outside source by way of a Modbus register.
87
Units
Metering Units
PAC3200
The PAC3200 provides open communications using Modbus RTU/ TCP, PROFIBUS-DP, and
PROFINET protocols for easy integration into any local or remote monitoring system.
Simple configuration of the meter can be done from the front display.
PAC4200
The PAC4200 is a feature packed power monitoring device that is suitable for use in
industrial, government and commercial applications where basic to advanced metering,
logging, and I/O is required. The meter may be used as a standalone device monitoring
over 200 parameters or as part of an industrial control, building automation or global
enterprise wide monitoring system. Advanced power quality monitoring and logging
applications range from single low voltage breaker / building metering to sub-station
main feeder monitoring, sub-billing or cost allocation installations with multiple tariffs.
Whether your goal is to reduce operation cost, reduce your carbon footprint or to
maintain your power assets, the PAC 4200 meter should be an important part of your
power monitoring system.
The PAC4200 provides open communication using the standard built-in Ethernet Modbus
TCP and has the capability of communicating through Optional Modbus RTU,
PROFIBUS-DP, and PROFINET protocol modules simultaneously. This allows for easy
integration into any local or remote monitoring system. The gateway functionality of this
device reduces installation cost by replacing other gateway devices and simplifying
wiring.

High Resistance
Ground Unit Option
High Resistance Grounding (HRG) systems have gained in popularity in
process application due to their ability to safely continue operation during a single line-ground fault and limit escalation of such a fault into a
multi-phase event. Siemens HRG MCC unit limits the ground fault current
which reduces the damage and stress to equipment and power system
components.
Why you should use HRG
90
Protect Equipment
Limit ground fault current to less than 10A, reducing damage
and stress to equipment and power system components.
Reduce Down Time
Process equipment can continue to operate in the event of a
line to ground fault, increasing profitability.
Fast Fault Location
Pulsing circuit and optional ammeter allow for easier fault
location, saving time and frustrations.
Units
HRG Catalog Numbers
The HRG MCC unit consists of a Front Control Plate, the
Internal Control Plate and an enclosed resistor.
All options are 2-10A, 60 Hz, 100kAIC, and include a

The standards structure is 90" (2286 mm) high, plus a 1.125" (29 mm) high channel sill.
Front-only (FO) structures can be either 15" (381 mm) or 20" (508 mm) deep. Siemens
provides a 21" (533mm) true back-to-back (BTB) design, consisting of a common
horizontal and vertical bus structure, for applications where available footprint is limited.
Moreover, we provide other back-to-back (BTB) mounted double deep structures which
are 30.5" (775 mm) or 40.5" (1029 mm) deep, and consist of two horizontal and vertical
buses. This allows for correct bus phasing on the front or rear. The standards structure is
90" (2286 mm) high, plus a 1.125" (29 mm) high channel sill. Front-only (FO) structures
can be either 15" (381 mm) or 20" (508 mm) deep.

A = Breaker Ampere Rating
For maximum protection the trip position should be set
as low as possible. Turn the adjustment screw counterclockwise to successively lower positions until the
breaker trips on motor starting. After this position is
determined, turn the adjustment screw clockwise to the
next higher setting for normal operation. The adjustment
screw is infinitely adjustable for customer convenience. If
the breaker does not trip at the lowest setting leave the
indicator at this setting. The instantaneous breaker is factory set at the LOW position.
WARNING
Fire, electric shock, or explosion hazard.
Can cause death, serious injury or
property damage.
To provide continued protection against risk of
fire or electric shock, examine and if damaged
replace current-carrying parts and other
components of combination controller. Tripping
(opening) of branch-circuit protection device
may be an indication that fault current has been
interrupted. If overload relay current elements
burn out, replace complete overload relay. To
maintain overcurrent, short circuit an ground
fault
protection,
follow
manufacturer’s
instructions for selecting current elements and
setting instantaneous trip circuit breaker.

Circuit breaker trip ratings are selected in accordance with NEC 2014 article 430.52 and table 430.52
assuming motors with locked rotor KVA Code B thru E. Lower trip ratings may be required for
motors with Code A. FLA per NEC 2014 table 430.250. Do not use to size heater coils.
Use motor NP data.
Maximum ratings shown on Heater Coil selection charts are not to be exceeded. Special applications
on motor may require different rating, refer to proper section of NEC to size.
Do not use this chart for part winding starters - Maximum breaker size to be limited to 200% FLA or
less, 150% for FLA greater than 100A.

1 UL does not permit fuses to be marked “current limiting” due to lack of rejection feature.
2 Class J smaller the NEC Code specifications; Class L requires bolt-on fuse blocks. Inherent rejection
feature of unique fuse dimensions allows UL marking of “current limiting” features.
3 Class “L” fuses may be marked “Time Delay” although UL does not investigate Time Delay characteristics
of such fuses.

To provide continued protection against risk of
fire or electric shock, examine and if damaged
replace current-carrying parts and other
components of combination controller. Tripping
(opening) of branch-circuit protection device
may be an indication that fault current has been
interrupted. If overload relay current elements
burn out, replace complete overload relay. To
maintain overcurrent, short circuit an ground
fault
protection,
follow
manufacturer’s
instructions for selecting current elements and
setting instantaneous trip circuit breaker.
The tripping current of any heater in a
40®C ambient is 25% greater than the
lower value of motor amperes shown in
the table.
Starters do not provide protection from
short circuits. A protective device should
be provided in accordance with the NEC
(CEC in Canada) and not exceed the values
shown in the table.
Note: If the rating specified is not a standard size for the circuit breaker manufacturer, use the next largest size.
Size 6
1 Ratings specified are for instantaneous
trip circuit breakers.
Maximum current rating for thermal magnetic circuit breakers is 250% of maximum
heater FLA.
Maximum current rating of fuses is:
a. 150% of maximum heater FLA for Class
R, K, or L (time delay).
b. 250% of maximum heater FLA for Class
K or L (non-time delay).
c. 300% of maximum heater FLA for Class J
(nontime delay).
WARNING
Fire, electric shock, or explosion hazard.
Can cause death, serious injury or
property damage.
Heaters shown in the table provide a maximum trip rating of 125% of the motor
name plate amperes, which is suitable for
40®C motors. For all other motors select
heaters one code number lower than specified in the table, which give a
maximum trip rating of approximately
115%.
WARNING
Hazardous voltage.
Can cause death, serious personal
injury, or property damage.
Automatic reset will continue to reset on
two-wire control. When not desired, use
three-wire control.
Do not use manual trip button when relay is
set in automatic reset positition.
If the calculated rating is between standard sizes, the next larger size may be
used. Fuse size may not exceed switch
size.
Wye-delta starters: If the motor nameplate shows the full load delta line current
only, divide this value by 1.73 or multiply
by .58 to select the proper heater rating

Motor Amps will vary depending on the type and
manufacture of the motor. These average values, usually
for T frame motors with service factor of 1.15 are to be
used only as a guide. The formulas on the previous page
may be used to obtain approximate amps for other motors.
NOTE:
Actual Motor Amps may be higher or lower than the values
listed below for a particular motor. For more reliable motor
protection, NEC requires selection of heater elements by
using the motor nameplate data. Motor nameplate data must
be checked to determine proper size of heater coil before
motor is energized.
