Cutler-Hammer

Moulded Case Circuit Breakers
16-2500 Amperes for IEC 60947-2 Applications

February 2001

Cutler-Hammer Frame Sizes G through R

General Information
Cutler-Hammer Moulded Case
Circuit Breakers provide increased
performance in considerably less
space than standard circuit breakers
or comparable fusible devices.
Reduced system costs can also be
realized because Cutler-Hammer
Circuit Breakers are used in series
rated systems, allowing the use of
lower interrupting circuit breakers
downstream.
Cutler-Hammer Circuit Breakers
meet applicable IEC 60947-2 standards, have been assigned ultimate
and service interrupting ratings per
IEC 60947-2, and employ adjustable
thermal and adjustable magnetic
trips.
The Cutler-Hammer family includes
seven frame sizes in ratings from
100 to 2500 amperes. Each frame
size offers a choice of several interrupting capacities up to 100 kA at
415 volts ac (200 kA at 240 volts ac).
This provides greater design flexibility than ever before possible while
also helping to save space.
Cutler-Hammer Circuit Breakers virtually eliminate the need for redesign and they can be used to replace
older circuit breakers in the same
panelboards, feeder pillars, busbar
trunking tap-offs, individual enclosures, machine tool control panels,
and motor control centres. In most
cases, the same connecting straps,
studs, and handle mechanisms can
be retained and used.
Standard calibration is 40°C. For
applications in high ambient temperature conditions, 50°C factory calibration is available.
Cutler-Hammer Circuit Breakers are
also provided for dc applications.
Interrupting ratings of 35 kA for
the 600 ampere frame have been
achieved for three-pole breakers
in series at 600 volts dc.

The Most Logically Designed
Contact Assembly
The flexibility and outstanding performance characteristics of CutlerHammer Circuit Breakers are made
possible by one of the most logically
designed contact assemblies in
circuit breaker history. Based on
previously patented Westinghouse
contact conductor designs, the CutlerHammer contact assembly creates a
high-speed “blow-open” action when
it confronts the electromechanical
forces produced by high-level fault
currents.
Cutler-Hammer Circuit Breakers are
operated by a toggle-type handle
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
remarkably 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 assured 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 certified facilities.
More Interrupting Capacity
in Less Space
Cutler-Hammer Circuit Breakers are
physically and electrically interchangeable with the “Classic” standard line of Westinghouse moulded
case circuit breakers. This means
Cutler-Hammer Breakers are ideal
for upgrading equipment designs
and retrofitting existing installations.
Current Limiting Characteristics
All Cutler-Hammer Circuit Breakers
are current limiting because of their
high repulsion contact arrangement
and incorporation of state-of-the-art
arc extinguishing technology.
Operating Mechanisms
Cutler-Hammer Circuit Breakers
have, in their basic version, a toggle
handle operating mechanism, which
also serves as switching position
indicator. As well as ON and OFF, the
further position TRIPPED is possible.
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 toggle handle must be brought
beyond the OFF position (RESET).
The circuit breaker can then be
reclosed.
As an additional switching position
indicator for F- to R-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 colours
red, green and white corresponding
to the ON, OFF and TRIPPED positions respectively.

Electrical Characteristics
DC Switching Duty
The E- to L-Frame circuit breakers
are also suitable for switching dc
currents.
The N- and R-Frame circuit breakers,
FWMP, KWMP, and LWMP circuit
breakers for motor protection 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 3- and 4-Pole Circuit Breakers
Proposed
Circuit

NSI-5178a

NSI-5179a

250 VDC

Double-pole switching.
If there is no risk of an earth fault, or if any
earth fault which occurs is immediately
eliminated (earth fault monitoring), the
maximum permissible dc voltage can be
600 volts.

M

Single-pole switching (earthed system).
Three conducting paths in series. The
earthed pole must be assigned to the

M

750 VDC

NSI-5181

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.

NSI-5180

PG.29B.01A.T.U

Remarks

440 VDC

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%.

Cutler-Hammer Frame Sizes K through R

Multi-Function
Electronic Trip Units
for All Applications
Digitrip™ RMS Trip Units
True rms Sensing
Digitrip RMS Trip Units utilize our
proprietary SURE™ Chip and SuRE
Plus™ Chip microprocessor-based
intelligence 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 K-, L-, N- and
R-Frames 63 through 2500 amperes.
Digitrip RMS 310 Trip Units are
available in four styles with either
fixed or adjustable rating plugs
which establishes the continuous
ampere rating of the breaker.
Rating Plugs
Digitrip RMS 310 Trip Units incorporate rating plugs that are interchangeable within a specific circuit
breaker frame. This provides the user
with versatility when establishing the
continuous current rating of a
breaker. Rating plugs are frequency
sensitive and may be specified for
50 / 60 Hz applications. Both fixed
and adjustable rating plugs are available, providing further flexibility
when applied to selectively coordinated systems.

Both Digitrip RMS 310 Trip Units are
available with ground fault pickup
and flat response ground fault delay
which provide the trip unit with full
function LSG and LSIG curve shaping flexibility.
Digitrip RMS 310 Trip Units can
effectively coordinate with both
sophisticated upstream power
breakers as well as downstream
thermal magnetic breakers…making
Digitrip RMS 310 Trip Units the costeffective reliable choice for selectively coordinated systems.
Thermal Memory
All Digitrip RMS Trip Units incorporate a long delay and, when ordered
with ground, a ground fault thermal
memory feature. Thermal memory
prevents the system from cumulative overheating due to repeated
overcurrent events that may occur
in quick succession.

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 fixed
rating plugs to establish the continuous ampere rating of the breaker.
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.

Note: Digitrip RMS rating plugs
are not interchangeable with
SELTRONIC™ 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.
The optional Digitrip RMS 310
provides additional flat response
short time delay adjustments on
an instantaneous setting to provide
LSI curve shaping capability.

System Diagnostics
All four Digitrip RMS models of trip
units provide long delay, short delay,
instantaneous, and ground fault
cause of trip LEDs on the front of the
unit. Digitrip RMS 610 and 910 also
offer a magnitude of trip information
as well as remote signal contacts for
improved system diagnostics.
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

PG.29B.01A.T.U

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
displayed 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
capable of displaying values of current harmonics in the digital display
window. Percentage of harmonic
content can be monitored for each
phase, neutral or ground, up to the
27th harmonic. Additionally, a total
harmonic distortion value can be
calculated and displayed.

Communications
Digitrip RMS 810 and 910 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 PowerNet System.
Field Testing
Integral field testing capability is
provided on all 610 and 910 Trip
Units. No additional test set is needed
to perform both trip and no trip field
testing.

Handle Mechanisms

Selection Guide and Ordering Information
Handle Mechanisms Overview
Handle Mechanisms are used to
operate moulded case circuit breakers, moulded case switches and
motor circuit protectors. They are
available in three basic configurations — Flange Mounted, Throughthe-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
■ G Direct
Handle mechanisms are typically
used on enclosed circuit breakers,
control panels and motor control
centres in many different applications. Cutler-Hammer has a handle
mechanism for virtually any need.
Flange Mounted Handle Mechanisms

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 mechanisms. The Flex Shaft
mechanism also takes up less interior
enclosure space than competitive

Cutler-Hammer Frame Sizes G through R

Selection Guide and Ordering Information
Remote Controlled Operating
Mechanisms
Cutler-Hammer Circuit Breakers
(sizes 160 to 2000 amperes) can be
equipped with motorized operating
mechanisms for remote in-service
closing and opening.
For normal remote opening, solenoid operating mechanisms F- and
K-Frames are available for circuit
breakers and motorized operating
mechanisms for J to R (sizes 250 to
2500 amperes) solenoid operating
mechanisms and motor operators
are always supplied with a locking
device for padlocks. This device can
be used for electrical and mechanical
blocking of the operating mechanism. All remote operating mechanisms are equipped with a manual
actuator for local operation.
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
undervoltage release.
Auxiliary Switches
Auxiliary switches are used for signalling and control purposes. The
various functions of the auxiliary
switches (changeover) are shown in
the top table to the right.
Shunt Trips
The shunt trip is used for remote
tripping.
The coil of the shunt trip is rated
only for short-time operation.

Undervoltage Releases
The circuit breaker cannot be closed
until the undervoltage release is
energized. 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.

It is not permissible with the circuit

Characteristics of the FWMP,

The tripping times of the inversetime delayed overcurrent releases
are only valid for the not preloaded
(cold) state. At operating temperature (after load with rated current),
the tripping times are reduced to
approximately 33%. After an overcurrent trip, the tripping times are
reduced according to the tripping
time characteristics (see figure
below) so that cooling down for
some minutes is required before
restarting the motor. During the first
minute after tripping, reclosing of
the circuit breaker is blocked.

Typical Specifications for
Cutler-Hammer Moulded
Case Circuit Breakers
The circuit breakers shall meet or exceed all standards as
defined in IEC 60947-2. Electrical circuits shall be protected
by Cutler-Hammer World Moulded Case Circuit Breakers
as manufactured by Cutler-Hammer.
Each pole of the one-, two-, and three-pole circuit breakers
shall provide complete circuit overcurrrent protection by
having inverse time and instantaneous tripping characteristics and, where applicable, be current limiting.
The circuit breaker shall be available in interrupting
families that provide 35-65-100 kA at 380-415 volts AC.
The circuit breakers shall be operated by a toggle-type
handle and have a quick-make, quick-break, over-centre
switching mechanism that is mechanically trip-free from
the handle so that the contacts cannot be closed against
short circuit currents. Tripping due to overload or short circuits shall be clearly indicated by the position of the handle.
The ON and OFF positions shall be clearly marked on the
cover of the circuit breaker along with the international
symbols I for ON and O for OFF on the handle, providing
positive indication of the circuit breaker contact position.
Additionally, a colour-coded indication of the circuit breaker contact position shall be provided: red for ON, green for
OFF, and white for TRIPPED. An easily accessible Push-ToTrip button for mechanically exercising the trip unit shall
be provided on the cover of each circuit breaker. All poles
of a multi-pole circuit breaker shall be so constructed as to
ensure simultaneous open, close, and trip operations.
Circuit breakers shall be completely enclosed in a high
strength glass-polyester case.
Noninterchangeable trip circuit breakers shall be factory
sealed; interchangeable trip circuit breakers shall have the
trip unit sealed to prevent tampering. Ampere ratings shall
be clearly visible from the front of the circuit breaker. Contacts shall be nonwelding silver alloy. Arc extinction shall
be accomplished by means of DE-ION® arc extinguishers
consisting of metal grids mounted in an insulating support.
The minimum interrupting ratings of the circuit breakers
shall be at least equal to the available short circuit current
at the line terminals.
The circuit breakers can be applied in series rated applications and subject to test data verification.
Circuit breakers in frame sizes 125 amperes through 250
amperes shall be equipped with thermal-magnetic trip
units. Circuit breakers 400 amperes through 2500 ampere
frame sizes shall be equipped with electronic trip units
that are insensitive to changes in ambient temperature
within the normal operating temperature range of the
circuit breaker. The 400 ampere and 630 ampere frame
sizes shall be designed to accept either thermal-magnetic
or electronic interchangeable trip units.
Electronic trip units shall be rms sensing type and have
unpowered thermal memory.

Circuit breaker ratings and modifications shall be
indicated on the drawings.
Circuit breakers shall be of the inverse time and instantaneous trip type as provided by thermal-magnetic or
electronic trip elements with either standard interrupting,
high interrupting, or current limiting characteristics
as required.
Moulded case circuit interrupters (motor circuit protectors)
shall be of the instantaneous (magnetic) only type, providing
instantaneous short circuit protection by means of a front
adjustable trip unit.
Moulded case switches shall be of the same construction
as the related listed circuit breaker and equipped with a
factory sealed, nonadjustable, high instantaneous only
short circuit protection.
Moulded case switches shall have no overload or low level
fault protection provided and shall be marked with a
maximum withstand rating denoting the type and level of
upstream protection required. Moulded case switches
shall be listed per IEC 60947-2.
Internally mounted accessories including alarm (signal)/
lockout switches, auxiliary switches, shunt trips, and
undervoltage released mechanisms shall be of the plug-in
type and shall be listed for field fitting in circuit breakers
which are not factory sealed.
Electrical operators for circuit breakers of the 400 ampere
frame size and below shall be of the solenoid type with
maximum five-cycle closing characteristics. Electrical
operators for circuit breaker frame sizes 630 amperes
through 2500 amperes shall be of the motor driven type.
All electrical operators shall be cover mounted. All
electrical operators shall be listed for field installation
per IEC 60947-2.
Electrical characteristics of accessories shall be as
indicated on the drawings.
Circuit breakers in the 125 amperes rating shall be supplied in one-, two-, three-, and four-pole models, as specified on the drawings. Circuit breakers in ratings of 225
amperes through 1250 amperes shall be supplied in two-,
three-, or four-pole models. The 2500 ampere circuit
breaker is available in three- and four-pole models as
specified on the drawings.
Accessory wiring shall be brought out through the side or
rear of the circuit breaker, or be connected to a terminal
block mounted on the side of the circuit breaker, as specified.
The ability to route accessory wiring to the opposite side
of the circuit breaker through a trough in the base shall be
provided.
Circuit breakers shall be provided with uniformly designed
nameplates to clearly indicate the type, rating, listing/
recognition/certification marks, accessory details, and
other information defined in IEC 60947-2.
