Series G Molded Case Circuit Breakers
15 – 2500 Amperes for UL, CSA & IEC Applications
Frame Sizes EG through RG (15 – 2500 Amperes)
Vol. 1, Ref. No. [02]
General Information
Cutler-Hammer Series G Molded Case
Circuit Breakers provide increased
performance in considerably less
space than standard circuit breakers
or comparable fusible devices.
The “G” signifies global applications:
Series G circuit breakers are marked
with UL, CSA
T
, CE, IEC and KEMA
KEUR listings. Other advantages
include:
■
Field-fit accessories.
■
Common accessories through
630 amperes.
■
Electronic trip units from 20 to
2500 amperes.
■
UL-listed and IEC-rated, 30 mA
ground fault/earth leakage modules.
■
Built-in ground fault protection
down to 20 amperes.
The EG, JG and LG frames are new
circuit breakers designed around
space-saving footprints. The NG and
RG use the proven Cutler-Hammer
Series C
T
ND and RD designs but use
metric threading on their line and
load conductors.
Cutler-Hammer Series G Circuit
Breakers meet applicable UL 489
and IEC 60947-2 standards.
The Cutler-Hammer Series G family
includes five frame sizes in ratings
from 15 to 2500 amperes. Series G
offers a choice of several interrupting
capacities up to 100 kA at 480 volts ac
(200 kA at 240 volts ac).
Standard calibration is 40°C. For appli-
cations in high ambient temperature
conditions, 50°C factory calibration
is available on thermal magnetic
breakers.
The Most Logically Designed
Contact Assembly
The flexibility and outstanding
performance characteristics of Cutler-
Hammer Circuit Breakers are made
possible by the best contact designs
in circuit breaker history. Our patented
technology creates a high-speed
“blow-open” action using the
electromechanical forces produced
by high-level fault currents.
Cutler-Hammer Circuit Breakers are
operated by a toggle-type mechanism
that is mechanically trip-free from
the handle so that the contacts cannot
be held closed against short circuit
currents. Tripping due to overload or
short circuits is clearly indicated by the
position on the handle. This remark-
ably fast and dependable contact
action is designed to enhance safety.
Thorough In-Plant Testing
The quality, dependability and reliability
of every Cutler-Hammer Circuit Breaker
is ensured by a thorough program
of in-plant testing. Two calibration
tests are conducted on every pole of
every circuit breaker to verify the trip
mechanism, operating mechanism,
continuity and accuracy.
ISO Certification
Cutler-Hammer Circuit Breakers
are manufactured in ISO
T
certified
facilities.
Current Limiting Characteristics
Cutler-Hammer Series G Circuit
Breakers are current limiting because
of their high repulsion contact
arrangement and use of state-of-
the-art arc extinguishing technology.
Operating Mechanisms
Cutler-Hammer Circuit Breakers have
a toggle handle operating mechanism,
which also serves as a switching
position indicator. The indicator shows
the positions of: ON, OFF and TRIPPED.
The toggle handle snaps into the
TRIPPED position if the breaker is
tripped by one of its overcurrent, short
circuit, shunt or undervoltage releases.
Before the circuit breaker can be
reclosed following a trip-out, the tog-
gle handle must be brought beyond
the OFF position (RESET). The circuit
breaker can then be reclosed.
As an additional switching position
indicator for EG- to RG-Frame circuit
breakers, there are two windows on
the right and on the left of the toggle
handle, in which the switching state
is indicated by means of the colors
red, green and white corresponding to
the ON, OFF and TRIPPED positions
respectively.

dc Switching Duty
The EG- to LG-Frame circuit breakers
are also suitable for switching dc
currents.
The NG- and RG-Frame circuit break-
ers are not suitable for dc currents
due to the solid-state overcurrent
release system.
For switching dc currents, however,
the maximum permissible dc voltage
per conducting path has to be
considered.
For voltages higher than 250 volts,
the series connection of two or three
conducting paths is required.
As the current has to flow through
all conducting paths so as to maintain
the thermal tripping characteristics,
the following circuit arrangements are
recommended. With dc, the trip values
of the instantaneous short circuit
release (“n” release) are increased
by 30 to 40%.

Remarks
250 Vdc Double-pole switching.
If there is no risk of an earth fault, or if any
earth fault which occurs is immediately elimi-
nated (earth fault monitoring), the maximum
permissible dc voltage can be 600 volts.
440 Vdc Double-pole switching (earth system).
The earthed pole must always be assigned to
the individual conducting path, so that two
paths are always in series in the event of an
earth fault.
600 Vdc Single-pole switching (earthed system).
Three conducting paths in series. The earthed
pole must be assigned to the nonswitched
conducting path.
750 Vdc Single-pole switching (earthed system).
Four conducting paths in series. The earthed
pole must be assigned to the nonswitched
conducting path.

Multi-Function Electronic
Trip Units for All Applications
Digitrip RMS Trip Units
True rms Sensing
Digitrip RMS Trip Units utilize our
patented microprocessor-based intelli-
gence to provide true rms sensing,
permitting increased accuracy and
reliable system protection. True rms
sensing is not susceptible to nuisance
tripping when waveforms containing
high harmonic currents are present.
Digitrip RMS 310
Digitrip RMS 310 Electronic Trip Units
are available with Cutler-Hammer
Circuit Breakers J-, L-, N- and R-
Frames 20 through 2500 amperes.
Digitrip RMS 310 Trip Units are avail-
able in four styles with either fixed
or adjustable rating plugs which
establishes the continuous ampere
rating of the breaker.
Note: JG- and LG-Frames have selectable
long time delay (tLD) and pickup settings
(Ir). A rating plug is not required.
Rating Plugs
If rating plugs are needed, they
are marked for 50/60 Hz applications.
Both fixed and adjustable rating
plugs are available, providing further
flexibility when applied to selectively
coordinated systems.
Note: Digitrip RMS rating plugs are
not interchangeable with SeltronicE
rating plugs.
Curve Shaping
When selectively coordinated systems
are called for, Digitrip RMS 310 will
provide a cost-effective solution for a
variety of applications.
The standard Digitrip RMS 310
includes an adjustable short time
pickup setting encompassing an I2t
ramp function which provides the
basic LS curve shaping function.
JG- and LG-Frames have an
adjustable long time delay.
Note: JG- and LG-Frames have selectable
long time delay (tLD) and pickup settings
(Ir). A rating plug is not required.
The optional Digitrip RMS 310
provides additional flat response
short time delay adjustments on
an instantaneous setting to provide
LSI curve shaping capability.
Digitrip RMS 310 Trip Units are
available with ground fault pickup
and flat response ground fault delay
which provides the trip unit with full
function LSG and LSIG curve shaping
flexibility.
Note: Contact factory for availability of
ground fault for LG-Frame trip unit.
Digitrip RMS 310 Trip Units can effec-
tively coordinate with both sophisti-
cated upstream power breakers as
well as downstream thermal magnetic
breakers…making Digitrip RMS 310
Trip Units the cost-effective reliable
choice for selectively coordinated
systems.
Thermal Memory
All Digitrip RMS Trip Units incorporate
a long delay. Thermal memory prevents
the system from cumulative overheating
due to repeated overcurrent events that
may occur in quick succession.
Field Testing
A field test kit is available for Digitrip
RMS 310 trip units.
Digitrip RMS 610 and 910
Digitrip RMS 610 and 910 Trip Units
are available with Cutler-Hammer
R-Frame Circuit Breakers 800 through
2500 amperes. Digitrip 610 and 910
Trip Units provide unparalleled
system protection with the added
convenience of a local display.
Curve Shaping
Digitrip RMS 610 and 910 Trip
Units are available with up to nine
curve shaping choices achieved by
adjusting up to seven switches on the
front of the unit for optimum system
coordination. Maximum curve shaping
flexibility is provided by dependent
long and short delay adjustments that
are long delay pickup (Ir) based,
depicted on the front of the unit by the
blue portion of the time-current curve.
Additional coordination capability
can be provided by utilizing the short
delay and ground fault zone selective
interlocking features available on
these trip units.

System Diagnostics
Digitrip RMS 610 and 910 models of
trip units provide long delay, short
delay, instantaneous, and ground fault
cause of trip LEDs on the front of the
unit. Their display shows a magnitude
of trip information, as well as remote
signal contacts, for improved system
alarming.
System Monitoring
Digitrip 610 and 910 Trip Units
have the capability to monitor
phase currents, as well as neutral or
ground currents. This information is
displayed on a large digital display
mounted on the unit.
Digitrip RMS 910 Trip Units can
also provide the user with power
and energy monitoring capability.
Peak power demand, present power
demand, and total energy, as well as
forward and reverse energy can be
monitored with this unit.
Digitrip RMS 910 Trip Units have the
additional capability of monitoring
line-to-line voltage, as well as system
power factor. Both parameters are dis-
played in the digital display window
and are supported by LEDs to indicate
which parameter is being displayed.
Harmonics Monitoring
Digitrip RMS 910 Trip Units are capa-
ble of displaying values of current
harmonics in the digital display win-
dow. Percentage of harmonic content
can be monitored for each phase,
up to the 27th harmonic. Additionally,
a total harmonic distortion value can
be calculated and displayed.
Communications
Digitrip RMS 910 units have built-in
communications options to allow all
protection, monitoring, and control
information to be transmitted back to a
central location via the Cutler-Hammer
PowerNetE system.
Field Testing
Integral field testing capability is
provided on all 610 and 910 Trip Units.
No additional test set is needed to per-
form both trip and no trip field testing.

30 mA Ground Fault
(Earth Leakage) Modules
Clockwise from Left: JG, LG, EG
MCCBs Shown with Ground Fault
(Earth Leakage) Modules
Eaton offers a 3- and 4-pole 30 mA
ground fault (earth leakage) protection
module for EG, JG and LG breakers.
The module does not restrict the use
of other breaker accessories. UL-listed
modules are available for JG and LG
MCCBs. The IEC-rated EG module
is side mounted for circuits up to
125 amperes, while the JG and LG
modules are both bottom mounted for
circuits up to 160 and 250 amperes (JG),
or 400 and 630 amperes for the LG.
The module is completely self-contained
since the current sensor, relay and
power supply are located inside the
product. Current pickup settings are
selectable from 0.03 – 10 amperes for
all IEC-rated modules and JG UL-listed
module, and 0.03 – 30 amperes for
the LG UL-listed modules. Time delays
are also selectable from Instantaneous
– 1.0 seconds for 0.10 ampere settings
and above. A current pickup setting
of 0.03 amperes defaults to an Instan-
taneous time setting regardless of
the time dial’s position. Two alarm
contacts come as standard: a 50% pre-
trip and a 100% after trip, both based
only on earth leakage current levels.

Special Features and
Accessories
Internal Accessories
Alarm Lockout
The alarm switches operate when
the circuit breaker is tripped by a short
circuit or overcurrent, but also when
it is tripped by a shunt trip or under-
voltage release.
Auxiliary Switches
Auxiliary switches are used for
signaling and control purposes.
The various functions of the auxiliary
switches (changeover) are shown in
Figure 15.
Shunt Trips
The shunt trip is used for remote
tripping.
The coil of the shunt trip is rated only
for short-time operation.
It is not permissible with the circuit
breaker open to apply a continuous
opening command to the shunt trip
in order to prevent the breaker from
closing. This means that interlocking
circuits with continuous commands
may not be set up with shunt trips.
Undervoltage Releases
The circuit breaker cannot be closed
until the undervoltage release is ener-
gized. If the release is not energized,
the circuit breaker can only perform
an idle switching operation.
Frequent idle switching actions
should be avoided as they shorten the
endurance of the circuit breaker.

Handle Mechanisms
Overview
Handle mechanisms are used to
operate molded case circuit breakers,
molded case switches and motor
circuit protectors. They are available
in three basic configurations — Flange
Mounted, Through-the-Door and
Direct (Close-Coupled) — providing
safe, dependable operation and ease
of installation.
Flange Mounted
■Flex Shaft
Through-the-Door
■Universal Rotary
Direct (Close Coupled)
■Universal Direct
■Euro IEC
Handle mechanisms are typically used
on enclosed circuit breakers, control
panels and motor control centers
in many different applications. Eaton
Electrical has a handle mechanism
for virtually any need.
Flange Mounted Handle
Mechanisms
The Flex ShaftE
Flange Mounted handle mechanisms
mount on the flange of an enclosure
door. The Flex Shaft is an extra
heavy-duty mechanism that includes
a flexible shaft in various lengths,
3 feet (0.9 m) through 10 feet (3 m)
for use with various size enclosures.
The Flex Shaft handle will accept up
to three padlock shackles, each with
a maximum diameter of 3/8 inch
(9.5 mm). Can be used with NEMA 12
fabricated enclosures. An optional
handle is available for Flex Shaft
that is suitable for use with NEMA 4
environments.
Flex Shaft comes preset from the
factory, requiring only minor field
adjustments on installation, which
takes about 10 minutes — a significant
time savings compared to installation
of other types of flange handle mecha-
nisms. The Flex Shaft mechanism
also takes up less interior enclosure
space than competitive designs and
the handle fits standard flange cutouts.
Flex Shaft handle can be remotely
mounted from breaker, where an
operator can use it by “funneling”
the cable through conduit.
Flex Shaft is UL listed under File
E64893 and meets CSA requirements.
Note: NEMA 4X handle mechanisms are
available. Add Suffix X to the complete
Catalog Number.
Original narrow handle design
(No C Suffix) is available. Remove C
from Catalog Number.
Note: When selecting the length of
shaft, ensure minimum bending radius
of 4 inches (101.6 mm) is maintained to
operate properly.
The standard method of shipment
includes the mechanism preset at
the factory; however, minor field
adjustments may be required.
Flex Shaft Ordering Information

enclosure types. An optional NEMA
4/4X handle mechanism is also avail-
able. All rotary handle mechanisms
include a handle “Lock Off,” to prevent
turning the breaker ON while in the
OFF position. All Rotary handles indi-
cate ON/OFF/Tripped/Reset positions,
however, Universal Rotary has
the added feature of international
markings for ON (I) and OFF (O).
The Universal Rotary is made of
molded material.
The Universal Rotary mechanisms
for EG, JG and LG MCCBs can be
operated by hand with the door open
or “locked off” to prevent operation
with the door open.
For the NG-Frame MCCBs, a
Cutler-Hammer Rotary with a metal
handle (Table 71) is also available.

Handle Mechanisms
Universal Direct (EG – LG)
Direct (Close-Coupled) Handle
Mechanisms mount directly to the
circuit breaker. They are used in shal-
low enclosures where the standard
variable depth Through-the-Door type
mechanism is not practical or cannot
be used. They are typically for applica-
tions where high volume, standardized
enclosures are being fabricated.
The Universal Direct handle mecha-
nism is designed exclusively for the
new Cutler-Hammer EG, JG and
LG circuit breakers. It is available
as standard with a door interlock to
prevent opening the enclosure while
the circuit breaker is in the ON
position. It is also available without
a door interlock.
The Universal Direct handle mecha-
nism is UL 489 listed, IEC 60947-1/2
and meets CSA requirements.
The Euro IEC Direct handle mechanism
is designed for NG and RG MCCBs.
The Euro IEC Direct handle mechanism
is 60947-112.

Time-Current Curves
Tripping Characteristics
The operating values specified for
the inverse time overcurrent releases
(thermal overload releases, “a”
releases) are mean values of the scat-
ter bands of all setting ranges from the
cold state and with uniform current
loading of the conducting paths.
The tripping characteristics of the
instantaneous (electromagnetic) short
circuit releases (“n” releases) are
based on the rated phase current In
which in the case of circuit breakers
with adjustable thermal overload
releases is also the upper value of the
setting range. With a lower setting
current, a correspondingly higher
multiple is obtained for the operating
current of the “n” release.
