Types GHBS and GBHS Solenoid-Operated, Remote-Controlled

Description
GHBS and GBHS circuit breakers are
bolt-on branch circuit breakers
designed for use in panelboards and
are ideally suited for lighting control
applications. In addition to providing conventional branch circuit
protection, they include a unique
solenoid-operated mechanism that
provides for efficient breaker pulseon and pulse-off operation when
used with a suitable controller like
the Cutler-Hammer Pow-R-Command lighting control system.

Typical Single-Pole Circuit Breaker Schematic Diagram and
Conductor Plug Wiring Connections

Remote Control Operation
The remote-control capability of
the breaker is “armed” when the
breaker handle is manually switched
to the “ON” position. Once armed,
the breaker can be pulsed “ON” and
“OFF” by a controller device which
provides an ac pulse of specified
magnitude and duration to the solenoid operated mechanism. Control
connections to the breaker are provided through a male conductor
plug (supplied by others) which

PG.74A.01.T.E

Circuit Breaker Schematic Diagram and Conductor Plug Wiring
Connections for 2-Pole

snaps into the female connector
provided with the breaker.
A normally open (a) auxiliary contact provides for breaker “ON”/“OFF”
status indication to the remote
controller and/or indicating lamp.
The remote-control capability of the
breaker is “disarmed” when the
breaker handle is in the “OFF” or
“TRIPPED” position. In the event
the breaker automatically trips, the
breaker must be reset manually.

Description
UL 1077 Supplementary Protectors
Type SPCL Supplementary Protectors are IEC circuit breakers that are
recognized by UL under UL 1077.
They are intended for use as overcurrent protection within an appliance or electrical equipment where
branch circuit protection (for example a UL listed Molded Case Circuit
Breaker) has already been provided
or is not required.
Equipment and Control
Circuit Protection
These protectors are ideal for replacing fuses in control circuits. Applications include protecting motor
control circuits, small control circuit
transformers, relays, contactor coils,
power supplies, PLC I/O points, appliances, and electronic equipment.

CSA 22.2
File No. LR105580-1

Overcurrent Curves

Thermal-Magnetic Overcurrent
Protection: Types B and C overcurrent curves provide maximum
reliability and accuracy. Type B
protection is normally used for low
inrush applications. Type C protection is used for general purpose
industrial applications that require
higher inrush tolerance.
Center Trip Position: The breaker
handle has a unique center trip
“Reset” position that indicates an
overcurrent trip. “Off” (O) and “On”
(I) handle positions are visually indicated by red and green flags.

Line and Load Terminals
Line and load terminals provide wire
connecting capabilities for specific
ranges of continuous current ratings
and wire types. Except as noted,
terminals comply with Underwriters
Laboratories, Inc., Standards UL486A
and UL486B. Unless otherwise
specified, F-frame circuit breakers

are factory equipped with load terminals only.
Ordering Information
F-frame circuit breakers and molded
case switches have load terminals
only as standard equipment. When
standard line-end terminals (same as

standard load-end terminals) are
required, add suffix L to the circuit
breaker catalog number. When nonstandard or optional line and/or load
terminals are required, order by
style number. Specify if factory
installation is required.

Line and Load Terminals
Line and load terminals provide wire
connecting capabilities for specific
ranges of continuous current ratings
and wire types. All terminals comply
with Underwriters Laboratories, Inc.,
Standards UL486A and UL486B

and CSA Standard C22.2 No. 65,
or Electrical Bulletin 1165. Unless
otherwise specified, K-frame circuit
breaker line and load terminals
are shipped separately for field
installation.

Ordering Information
K-frame circuit breakers use Cu/AI
terminals as standard. When
optional copper or Cu/AI terminals
are required, order by catalog number. Specify if factory installation is
required.

Series C L-Frame

Line and Load Terminals
Line and load terminals provide wire
connecting capabilities for specific
ranges of continuous current ratings
and wire types. All terminals comply
with Underwriters Laboratories, Inc.,
Standards UL486A and UL486B
and CSA Standard C22.2 No. 65M.
Unless otherwise specified, L-frame
circuit breaker line and load terminals are shipped separately for field
installation.

The wire connecting terminal is
secured with two pan-head, slotted
screws and lock washers which can
be checked for the correct torque
loading or retightened from the
front of the circuit breaker before
installation of the conductors.
(Applies to all styles.) The circuit
breaker line/load terminal conductors are positioned in the conducting
holes in the wire connecting terminal

and are secured with recessed socket
screws which are tightened to the
correct torque loading from the front
of the circuit breaker.
Ordering Information
L-frame circuit breakers use Cu/AI
terminals as standard. When optional
copper terminals are required, order
by catalog number. Specify if factory
installation is required.

The type ELC current limiter attachment for the Series C
MCP is designed to provide increased interrupting capacity. The combination may be used for the application up
to 200,000A symmetrical at 600 Vac making the MCP suitable for use in network distribution systems or other
applications where unusually high fault currents are
available. The current limiter connects to the load end
of the MCP and is provided with terminals suitable for
copper or aluminum conductors. (See table).
Limiters are coordinated with the MCP so that normal
fault currents are interrupted automatically by the MCP
without any damage to the limiter. Only the rare very
high fault is opened by the limiter. Faults that are interrupted by the limiter are interrupted by the limiter also
magnetically trip the MCP, opening all three poles,
preventing single-phase operation.
Each of the three poles of the type ELC limiter is
equipped with an indicator that extends when a fault is
interrupted by the limiter.

➀ Motor FLA ranges are typical. The corresponding trip setting is at 13
times the minimum FLA value shown. Where a 13 times setting is
required for an intermediate FLA value, alternate cam settings and/or
MCP ratings should be used.
➁ For Dc applications, actual trip levels are approximately 40% higher than
values shown.
➂ Settings above 130 amperes are for special applications. NEC Article
430-110(a) requires the ampere rating of the disconnecting means to be
not less than 115% of the motor full load ampere rating.
➃ Terminal wire connectors are UL listed for standard stranded wire sizes
as defined in UL486A or UL486B.
➄ Optional on special order for copper cable only.

Molded Case Circuit Breakers
Series C Earth Leakage Circuit Breakers

General Information

Applications

Series C Earth Leakage Breakers
offer superior Class 1 ground fault
protection and improved ground
fault coordination capability.

Three-Phase, Four-Wire Loads
For three-phase applications with
line-to-neutral loads, select 4-pole
earth leakage breakers and wire the
neutral through the fourth (right) pole.

Earth leakage ground fault protection
differs from other types of systems in
its level of sensitivity. The sensitivity
of traditional devices is limited by the
cumulative error of the residual current sensors and the placement of
the phase and neutral conductors
inside the current sensor.
Leakage breakers are zero sequence
sensing devices. They are factory
supplied with a single sensor and
ground fault relay built-in. This technique allows for protection sensitivities down to the 30 milliampere level.
Typical Series C Earth
Leakage Circuit Breaker

PG.74A.01.T.E

Leakage breakers are provided with a
full complement of easy adjustments. The ground fault pickup setting is adjustable from 0.03 to 30
amperes in eight steps, and the
ground fault time delay setting is
adjustable from instantaneous to 2.0
seconds in six steps. When the
pickup is set to 30 mA, the time delay
setting defaults internally to instantaneous only. Increased selectivity provides for improved coordination with
upstream and downstream ground
fault devices as well as the flexibility
to adjust for transient currents.

Three-Phase, Three-Wire Loads
For applications with only threephase, three-wire, line-to-line connected loads, select 3-pole earth
leakage breakers.
Single-Phase Loads
For single-phase, two-wire or threewire applications, use a 3-pole earth
leakage breaker and connect all conductors through the breaker.

Accessories
Optional Factory Installed
Internal Accessories
Earth leakage breakers use the same
internal accessories as standard F-,
J- and K-Frame Series C Breakers.
Internal accessories fit in the righthand pole space and are available as
factory modifications only.
Optional External Accessories
Series C Earth Leakage Breakers use
the same external accessories as the
standard F-, J- and K-Frame circuit
breakers.

Drawout Frame

These drawout frames are for use
with standard 3-pole Cutler-Hammer
molded case circuit breakers. They
consist of two separate parts; stationary mounting frame and movable carrier frame. Slide rails are
drawer-type, and a screw mechanism is used to engage or withdraw
the movable carrier frame.
The drawout frames have three
positions: connected, test and
disconnected. The frames do not
include a safety tripping interlock,
or secondary contacts. These are
optional items and may be ordered
at additional cost.

Secondary Contacts
These are used to disconnect auxiliary circuits when attachments such
as shunt trip or motor operator are
used. Available in multiples of four
contacts with a maximum of 32 contacts for the NB Tri-Pac. They must
be factory mounted. Order by
description as similar to stationary
or moving frame and specify number of contacts required.

General Information

Interrupting Capacity Ratings

Standards

Engine generator molded case circuit
breakers are designed specifically for
application on diesel engine powered standby generators where high
interrupting circuit breakers are not
required. The JG through NG breakers are equipped with a special trip
unit, that includes standard thermal
(overload) protection and special low
magnetic pickup range (FG includes
a fixed thermal/magnetic pickup).
The standard thermal trip unit
provides overload protection for
conductors per the National Electric
Code. The low magnetic pickup
range is approximately two to five
times the continuous rating and
provides closer low level short circuit
protection when applied on generators that have very low short circuit
capacity. This combination allows
the user to customize the breaker to
the generator output.

Type GFM Ground Fault Protection Device

Description
Cutler-Hammer Type GFM devices
are Class 1 Ground Fault Sensing
and Relaying devices designed to
comply with the requirements outlined in Underwriters Laboratories,
Inc. Standards for Safety entitled:
Ground Fault Sensing and Relaying
Equipment, UL1053.
Type GFM devices, when properly
installed on a grounded electrical
distribution system, will sense phase
to ground fault currents and cause a
disconnect to open and clear the
fault instantaneously at predetermined current values. These devices
have a maximum voltage rating of
600V, 50/60 Hertz and may be
applied in accordance with Article
230-95 of the National Electrical
Code.
Type GFM Ground Fault Protective
Devices are self-contained combination sensing and relaying devices
designed primarily for application
on motor circuits and fixed loads
where low-level Ground Fault Equipment Protection is required.
GFM devices are available in two
basic types with each type having
two physical sizes. The two basic
types differ in the type of output
circuit provided. The first type,

PG.74A.01.T.E

Trip Indication/Reset
A combination visual indicator and
reset button is provided on the top
of Type GFM2 and GFM4 devices to
indicate the initiation of a tripping
action to clear a Ground Fault. The
operation of the internal relay will
cause the white button to visibly
raise.
To reset the device, the Indicator/
Reset button must be depressed.
Failure to reset the device will not
allow the associated disconnect
device to be reclosed.

The proper size selection is a function of the conductor size of the
equipment being protected. Types
GFM2/GFM2A have approximately a
two-inch window opening. Types
GFM4/GFM4A have approximately a
four-inch window opening.

No Indicator/Reset button is provided on Types GFM2A or GFM4A
since an internal SCR is used in the
output circuit. These devices reset
automatically when the disconnect
opens to clear the Ground Fault.

Rating Selection

Type GFM devices may be installed
in Zero Sequence or Ground Return
Sensing methods, Proper Ground
Fault Protection schemes are dependent upon proper system installation
and grounding methods.

The basic Ground Fault Current
Pickup rating of either type GFM
device is 5 amperes, i.e., each unit
when properly installed will initiate a
trip signal to a remote shunt trip
with the presence of a 5 ampere
Ground Fault Current within established tolerance limits. Separate
optional rating plugs are available to
alter the pickup rating to a maximum
of 100 amperes.

Control Power
Internal control power is not
required to operate Type GFM
Ground Fault Protective devices. All
internal control power required is
derived from the Ground Fault current through the internal current
sensor.
External control power is required to
operate the remote shunt trips used
in conjunction with Type GFM2 and
GFM4 devices.
External control power is not
required with Type GFM2A and
GFM4A devices to operate the special remote, low-energy, flux transfer
shunt trips used in molded case circuit breakers.

Application

Mounting
Each Type GFM device contains a
Ground Fault Sensor which is a special current transformer. These are
insulated devices which can be
mounted directly to enclosure surfaces. Four tubular rivets secure the
sensor housing. These four (0.200
dia.) mounting holes can be used
to mount the GFM device in either
a vertical or horizontal mounting
position.
Optional mounting brackets as
shown on the next page are available.
These brackets may be mounted on
either the bottom or side depending
upon the installation requirements.
Regardless of the mounting method
used, the top of the device with the
visual indicator/ reset button and
nameplate instructions should be
maintained in a visual position after
installation. GFM devices should be
installed so that all conductors passing through the conductor window
are physically centered.

Type GFR

Type GFR
Description
The GFR ground fault relays, current
sensors, test panels and accessory
devices are UL listed by Underwriters Laboratories, Inc. in accordance
with their standard for Ground Fault
Sensing and Relaying Equipment,
UL 1053, under File E48381.➀
A Type GFR ground fault protection
system, when properly installed on a
grounded electrical system, will
sense phase-to-ground fault currents. When the level of fault current
is in excess of the pre-selected current pickup and time delay settings,
the GFR relay will initiate a trip
action of a disconnect device, which
will open the faulted circuit and clear
the fault.
The GFR devices are UL Class I
devices designed to protect electrical equipment against extensive
damage from arcing ground faults.
A basic Type GFR ground fault protection system consists of a ground
fault relay➁, a ground fault current
sensor and a disconnect device
equipped with a shunt trip device.
This disconnect device can be a
molded case circuit breaker, a power
circuit breaker, a bolted pressure
switch or other fusible disconnect
device, suitable for application with
UL Class I Ground Fault Sensing and
Relaying equipment.
Additional optional equipment can
be added to the protection system to
meet the requirements of the specifying engineer, including:
■

Ground Fault Test Panel

■

Ground Fault Warning Indicator
Relay

■

Ground Fault Indicating Ammeter

GFR relays are available with zone
selective interlocking circuitry to
interlock several relays within the
same system. This allows the relay
which detects a ground fault to

mounting.
➁ These devices are also listed with CSA under
their file number 43357.

PG.74A.01.T.E

GFR Relay

instantly clear the fault by tripping
the disconnect device. The relay
simultaneously sends a signal to
relay units “upstream” from the
fault to time delay or to block their
operation completely. Current sensors in various designs provide a
range of “window” sizes to accommodate standard bus and cable
arrangements.
Shunt trip attachments may be
ordered for field mounting in CutlerHammer molded case circuit breakers, or may be ordered factory
installed in the breaker.

a

The shunt trip provides remote controlled tripping of the circuit breaker.
The shunt trip consists of an intermittent rated solenoid with a tripping plunger and a cutoff switch
assembled to a plug-in module.

When required for ground fault protection applications, certain Ac rated
shunt trips, as noted in the Electrical
Rating Table, are suitable for operation at 55 percent of rated voltage.

Ordering Information
Select shunt trip catalog number
for the voltage within the indicated
voltage range. Shunt trip coils are
designed to be applied at specific
Ac or Dc voltages within the voltage
range shown. Electrical ratings are
also shown on applicable circuit
breaker accessory nameplates.

Low Energy Shunt Trip

Low Energy Shunt Trip
ST
LE

General Information
microfarad capacitor charged to 28
Vdc is discharged through the shunt
trip coil, the resultant flux opposes
the permanent magnet flux field,
which releases the stored energy in
the spring to trip the circuit breaker.
As the circuit breaker resets, the
shunt trip reset arm is actuated by
the circuit breaker handle, resetting
the shunt trip. The plug-in module is
mounted in retaining slots in the top
of the trip unit. Coil is intermittentrated only. Cutoff provisions
required in control circuit.

Low energy shunt trip devices are
designed to operate from low
energy output signals from dedicated current sensors typically
applied in ground fault protection
schemes. However, with a proper
control voltage source, they may be
applied in place of conventional trip
devices for special applications. Flux
paths surrounding permanent magnets used in the shunt trip assembly
hold a charged spring poised in
readiness to operate the circuit
breaker trip mechanism. When a 100

Undervoltage Release Mechanism

Undervoltage Release
Mechanism
UV

General Information
The undervoltage release mechanism monitors a voltage (typically a
line voltage) and trips the circuit
breaker when the voltage falls to
between 70 and 35 percent of the
solenoid coil rating.
The undervoltage release mechanism consists of a continuous rated
solenoid with a plunger and tripping
lever mounted in a plug-in module.
The tab on the tripping lever resets
the undervoltage release mechanism

when normal voltage has been
restored and the circuit breaker
handle is moved to the reset (or OFF)
position. With less than pickup voltage applied to the undervoltage
release mechanism, the circuit
breaker contacts will not touch when
a closing operation is attempted.
Note: Undervoltage release mechanism accessories are not designed for,
and should not be used as, circuit
interlocks.

Ordering Information
Select handle reset undervoltage
release mechanism catalog number
for the voltage within the indicated
voltage range. Undervoltage release
mechanism coils are designed to be
applied at specific Ac or Dc voltages
within the voltage range shown.
Electrical ratings are shown on applicable circuit breaker accessory
nameplates.

Termination Hardware

Terminal End Covers

Interphase Barriers

F-Frame

The interphase barriers provide
additional electrical clearance
between circuit breaker poles for
special termination applications.
The barriers are high dielectric insulating plates that are installed in the
molded slots between the terminals.
(Field installation only.) Two per
package.

The terminal end covers are
designed for use in motor control
center applications where, because
of confined spaces, line side conductors are normally custom fitted. The
molded end covers are made of high
dielectric glass-polyester and slide
over the line ends of the circuit
breaker. Close fitting conductor
openings are molded into the end
covers. The end cover and circuit
breaker case fit together to form
terminal compartments that isolate
discharged ionizing gases during circuit breaker tripping. Terminal end

The sliding bar interlock provides
mechanical interlocking between
two adjacent 3-pole circuit breakers.
It is installed on the enclosure cover
between the circuit breakers. When
the sliding bar interlock handle is
moved from one side to the other,
a bar extends to alternately block
movement of the circuit breaker
handles and prevents both circuit
breakers from being switched to ON
at the same time. Sliding bar interlocks are not UL listed. (Field installation only.)

The sliding bar interlock is available

Walking Beam Interlock
The walking beam interlock provides
mechanical interlocking between
two adjacent circuit breakers of the
same pole configuration. The walking beam interlock mounts on a
bracket behind and between the circuit breakers. A plunger on each end
of the beam is inserted through an
access hole in the back plate and
base of each circuit breaker. The
walking beam interlock prevents
both circuit breakers from being
switched ON at the same time. If a
walking beam interlock is installed,
the wiring troughs in the back of the
circuit breaker case are blocked by
the plungers and cannot be used for
cross wiring. Factory modified circuit breakers are required for this
application. UL File E3816.

PG.74A.01.T.E

The walking beam interlock is available for mounting between two adjacent circuit breakers spaced 1/4-inch
apart and having the same pole configuration. The two circuit breakers
must be factory modified to accept
the walking beam interlock assembly
(suitable for use with either 2-, 3-, or
4-pole circuit breakers). With properly
modified circuit breakers, the walking
beam interlock is suitable for field
installation. Order circuit breakers
specifying modification for walking
beam and select walking beam interlock from table on this page. Circuit
breakers and walking beam interlock
are boxed and shipped separately.

Electrical Rating Data➁

The electrical (solenoid) operator is
a single solenoid mechanism that
enables local and remote circuit
breaker ON, OFF, and reset switching. The electrical operator is
mounted on the circuit breaker
cover within the trimline of the circuit breaker. The electrical operator
uses a unique bistable latch that
allows the device to operate using
one solenoid. The accessory provides high-speed switching with a
maximum operating time of 5 cycles
(80 ms) making it suitable for generator synchronizing applications.
Means are provided for remote electrical operation and for local manual
operation. A special slide includes
provisions for padlocking the circuit
breaker handle in the OFF position.
The slide will accept three padlock
shackles with a maximum diameter
of 1/4-inch (6 mm) each. An interlock
electrically disconnects the solenoid
when the electrical operator cover is
removed. The above table provides
electrical rating data for the electrical (solenoid) operator.

The SM safety handle mechanism
provides a means of externally operating a circuit breaker mounted in an
enclosure and is designed to reduce
the possibility of circuit breaker tampering. The handle mechanism is
especially suited for use in automotive and machine tool industries
through its conformance to Type 12
and J. I. C. requirements. A specially
modified handle mechanism for
Type 4 enclosure application is also
available order by description. The
handle mechanism will accept up to
three padlock shackles, each with a
maximum diameter of 3/8 inch
(9.52mm). UL File E64893.

The MC motor control handle mechanism is a linear-operating, fixeddepth mechanism designed for
through-the-door mounting in standardized and shallow depth enclosures. The handle mechanism provides positive operation and direct
disconnect status indication. It is
interlocked with the enclosure door
so that the door can be opened only
when the handle is set to OFF.
(A defeater, supplied with the handle
mechanism, can be used to bypass
the interlock for maintenance and
inspection.) The handle mechanism
will accept up to three padlock shackles, each with a maximum diameter
of 3/8 inch (7.92 mm).UL File E56845.

OPTIM System Components

Breaker Interface Module
(BIM)

The Breaker Interface Module (BIM)
is a panel mounted user interface
device that is mounted on the front
of an electrical assembly or at a
remote location. The BIM is used to
access, configure, test and display
information for OPTIM trip units and
other devices. The BIM consists of
four display windows, eight function
buttons, 18 LEDs, and a graphical
time/current curve to provide
breaker status, operational information, protection status and energy
monitoring. A 24 Vdc power supply
is required to provide power to the
BIM. This is supplied by the switchboard builder to Cutler-Hammer
specifications. The BIM is a member
of the Cutler-Hammer PowerNet
family of communicating devices
that connects OPTIM trip units,
Digitrip RMS 810/910 trip units and
energy sentinels as a subnetwork
system. The BIM can also be connected to a main network via a PONI
module to Cutler-Hammer PowerNet
software.

Digitrip OPTIMizer

The Digitrip OPTIMizer is a handheld programmer that is used to
access, configure, test and display
information from OPTIM trip units.
The OPTIMizer plugs into the front
of an OPTIM trip unit via an eightpin telephone jack and is powered
by a nine-volt battery or the auxiliary power module. In addition,
a three-pin INCOM network connection is also provided to program
other OPTIM devices on the system.
An Auxiliary Power Module connection provides a trip test when control power is not present at the
breaker. The OPTIMizer is supplied
as a standard package to include the
programmer, the eight-pin connection cord, battery and carrying case.
The Auxiliary Power Module is
optional.

Auxiliary Power Module

The Auxiliary Power Module is a
power supply requiring 120 Vac
input at 50 or 60 Hz that provides a
32 Vdc output➀. The Auxiliary Power
Module provides control power for
testing an OPTIM trip unit when
other means of control power is not
available or for continuous OPTIMizer
operation versus temporary with a
battery. The Auxiliary Power Module
connects into the top of the Digitrip
OPTIMizer via a keyed receptacle.
The main application for the Auxiliary Power Module would be for the
testing of a stand-alone non-communicating OPTIM breaker that ordinarily would not have control power.

PG.74A.01.T.E

Note: 24 Vdc Power Supply
A 24 Vdc power supply is required for all Digitrip
OPTIM trip units that are required to communicate either on the main Cutler-Hammer PowerNet
network or as a subnetwork to a BIM. The breaker’s load is 45 mA of current. Typically one power
supply is required per switchboard and can provide control power to a BIM and the OPTIM trip
units. The 24 Vdc power supply should be an
“isolated high quality” power supply with a
“CE” label, and is normally provided by the
switchboard manufacturer to Cutler-Hammer
recommendations.

Series C Digitrip OPTIM trip units
can communicate back to a central
Personal Computer by installing
Cutler-Hammer PowerNet software➁.
In addition other software packages
are available to allow the user to
configure the trip units as well as
monitor system performance.
