3200 amperes in the same frame
with uniform 125 mm pole center
spacing. Withstand ratings are
available to 85 kA at 690 Vac and
interrupting ratings to 100 kA at 440
Vac for improved system coordination
and service continuity.
The MWI double-wide frame is
ideal for application as main and
tie breakers in high capacity power
distribution systems. Continuous
current ratings are available in 4000,
5000, and 6300 amperes. Withstand
and interrupting ratings are available

Summary
Rigid Frame Housing
Magnum circuit breakers use a rigid
frame housing construction of engi-
neered thermoset composite resins.
This material is strong and lightweight
having a strength to weight ratio
twice that of steel. In addition to
high strength structural properties,
this material has excellent dielectric
characteristics and resists arc tracking.
The 3-piece construction provides
support while isolating and insulating
power conductors:
❶A 2-piece case encloses current
paths and arc chambers. The chambers
act to channel arc gases up and out
during interruption.
❷The operating mechanism and
accessories sit on the front of the
indicating functions and guiding
operations. Field installable accessory
items can be identified by name and
rating through viewing windows.
An optional padlockable cover limits
access to the “ON” and “OFF” push-
buttons. Complete access to the
“ON” pushbutton can be prevented
with an optional prevent close cover.
case and are covered by an insulating
front cover. Only the cover needs to
be removed to access the mechanism
or add accessories.
The overall strength and rigidity of
the design also contributes to higher
performance capabilities:
■Higher Withstand
■Higher Interrupting
The Magnum rigid frame housing
design allows for precise construction,
eliminating the need for adjustments.
The significantly reduced frame
deflection during operation along
with stiff component mounting
results in a longer life operating
mechanism.

Main Contact System
Single Contact Finger
The performance characteristics of
the Magnum air circuit breaker are
primarily attributed to the contact
design and its movement. A single
contact finger is the focal point of the
moving contact. This single contact
performs both the main and arcing
contact functions on different parts
of the same finger.
A complete movable contact assembly
is merely a combination of a number
of single contact fingers. The exact
number of contact fingers required
depends upon the frame size and
interrupting rating of the circuit
breaker.
heel to toe and toe to heel. When the
circuit breaker is closed, the “Heel”
(main contact portion) is in contact
with the stationary contact and carrying
current. At the same time, the “Toe”
(arcing contact portion) is separated
from the stationary arcing contact.
A compact “C Loop” current path per-
mits electromagnetic forces, primarily
produced as a result of a fault current,
to supplement the closing contact
forces provided by the operating
mechanism. This helps to accomplish
two important things:
■Operating mechanism does not
have to be as large or heavy
■Higher short time ratings (withstand)
are achievable
The braided connectors (flexible shunts)
used to attach each contact finger serve
several important purposes:
■Eliminate bolted joints reducing
hot spots
■Reduce required mounting space
for primary contacts
■Allow contact finger motion for
“Heel - Toe” rocking
Heel-Toe Action
The “Heel-Toe” movement of the
contact fingers is a critical factor in
the efficiency of the Magnum main
contact system. The main contact
portion can be viewed as the “Heel”
and the arcing portion the “Toe.” Its
movement is similar to the rocking of
a foot forward and backward from

side ledge inside the arc chamber.
When the contacts are in good condi-
tion, the narrow ledge is covered by
the back end of the contacts and not
visible. When the narrow ledge
becomes visible with the primary
contacts closed, contact replacement
is indicated.
Contact Wear Indicator
A contact wear indicator provided for
each primary contact structure permits
their condition to be determined.
This is accomplished by viewing
the contacts while in the closed
position only.
The contact wear indicator is the
relative position of the individual

Arc Chambers
Arc chambers, one per pole, are used
to insulate and isolate each pole from
one another, from the rest of the circuit
breaker, and from operating personnel.
Arc Chute
Enclosed within each arc chamber is
an arc chute which mounts over each
set of primary contacts. Alternating
V-shaped arc chute plates effectively
attract the arc and interrupt it. Each
arc chute has a baffled cover to
assist with the speed and efficiency
of the interruption.

Manual Operation
On manually operated circuit breakers,
the closing spring is charged manually.
This is accomplished through the use
of the front mounted spring-charge
handle. It takes from 5 to 7 downward
strokes on the handle to complete the
charging process.
Standard manually operated circuit
breakers are closed and opened by
hand using the front mounted
Manual “ON” and Manual “OFF”
buttons respectively. Access to these
buttons can be limited by the use of
an optional, padlockable cover.
Complete access to the “ON” button
can be prevented with an optional
prevent close cover. Spring and
primary contact status indicator
windows are located just above the
pushbuttons.
Optional electrically operated devices
are available to automatically close
or trip open manually operated circuit
breakers, and are field installable.
An optional motor operator is used
to charge the closing spring automat-
ically. It can be field installed in a
manually operated circuit breaker.
Manual circuit breakers are pre-wired
for this addition.
Electrical Operation
The closing spring is charged auto-
matically by the optional motor
operator. It can also be manually
charged.
Manual “ON” and Manual “OFF”
buttons are also provided as
described under manual operation.
Through the use of a mechanical
anti-pump feature, an open circuit
breaker only accepts one attempt to
reclose even if the close command
continues, preventing motor operator
burnout.
A standard circuit breaker with
electrical operation also has optional
electrically operated devices available
to automatically close or trip open
the circuit breaker.

Breaker Secondary Connectors
(Black)
Magnum secondary connectors pro-
vide reliable low impedance connec-
tions for up to 60 terminal points of
breaker control wiring. The sec-
ondary connectors are black in color
and consist of 2 blocks, each with 30
terminal points. The terminals
receive plug-in type pin and socket
wire terminals. Terminal points have
dedicated locations to receive the
breaker accessory devices and to
facilitate standardized automated
testing of the control wiring and
accessories during breaker manufac-
turing. Labels are provided on the
blocks to assist the customer in ter-
minal point identification and use.
The dedicated secondary connectors
make it easy to add accessories (like
shunt trips, spring release devices,
etc.) to the breaker at the point of use
with field option kits. Wiring removal
from breaker secondary connector is
easily accomplished using an extrac-
tion tool (AMP part number 305183).

Digitrip RMS
Trip Unit Summary
Magnum circuit breakers can use any
one of a family of microprocessor-
based, true rms sensing Digitrip RMS
electronic trip units:
■Digitrip RMS 220
■Digitrip RMS 520i
■Digitrip RMS 520Mi
■Digitrip RMS 520MCi
■Digitrip RMS 1150i
The trip units themselves are self
powered; no external power is
required to operate the portective
systems. Current signal levels and
the control power are derived from
integrally mounted torroidal wound
current sensors. The use of torroidal
wound sensors reduces magnetizing
currents, resulting in improved
metered value accuracy over a broad
range of sensor ratings.
Common Features
All trip units have a green light emit-
ting diode (LED), labeled
Status
,
which blinks approximately once
each second to indicate that the trip
unit is operating normally. This
same
Status
LED will blink at a faster
rate if the trip unit is in a pick-up or
overload condition.
Trip units are interchangeable in the
field, except for Model 520MC and
Model 1150. Contact Cutler-Hammer
for interchangeability details.
A functional local test of a major
portion of every trip unit’s electronic
circuitry and the circuit breaker’s
mechanical tripping action can be
verified through the trip unit’s test
receptacle. Every test receptacle is
supplied with a test receptacle cover.
This is accomplished using a Digitrip
Test Kit which provides a secondary
injection test. A small hand held
functional Test Kit can also be used
to check circuitry and mechanical
tripping functions. In addition, the
model 1150 trip unit has an integral
testing system.
Rating Plugs
All Magnum circuit breaker trip units
use a fixed type rating plug. Rating
plugs are available in ampere ratings
of 200 through 6300 amperes. The
current rating of the rating plug
must match the current rating of the
integrally mounted current sensors.
Therefore, the continuous current
rating of the circuit breaker cannot
be changed by only changing the
rating plug.
The rating plug performs a number
of functions:
■It tells the trip unit what the rating
is of the current sensors. A label
on the rating plug clearly states
that the rating plug and current
sensors must have the same rating.
■It determines the maximum instan-
taneous setting which is a function
of the current sensor rating.
Lifting the rating plug lid will expose
a small battery which supplies power
for the trip unit’s cause of trip LEDs.
If the rating plug is removed from
the trip unit, the circuit breaker will
open (trip) if it is carrying current.
The rating plug should always be
secured in position when the circuit
breaker is in use.
All trip unit models, except for model
220, have red LEDs on the face of the
trip unit to indicate the cause for an
automatic trip operation, for example
earth fault, overload or short circuit.
They flash red to make the indication.
A battery in the trip unit maintains
the trip indication until the
Reset/Battery Test button is pushed.
The battery is satisfactory if its LED
lights green when the Battery Check
button is pushed.
A clear, tamper-proof, plexiglass
cover sits on the front of the circuit
breaker over the trip unit. This cover
allows the settings to be viewed but
not changed, except by authorized
personnel. The cover is held in place
by two cover screws. Security is
insured by the insertion of a standard
meter seal through the holes in both
of the cover retention screws.

Potential Transformer (PT)
Module
The PT module provides system line
voltage information to the Digitrip
1150 Trip Unit. It consists of a 3-phase,
3-wire input and 3-wire output step
down transformer with a wye to wye
hookup. A white disconnecting plug
is provided to disconnect the PT
Module circuit from the line voltage
during dielectric testing.
The PT Module primary input voltage
connection is selected when the
breaker is ordered to accommodate
normal or reverse feed application.
PT Module line-side pr load-side
voltage connections are made via
hard wire termination to the breaker
upper or lower conductors.
The normal convention is that the
breaker line side is the upper con-
ductors, with power flowing through
the breaker from top to bottom. In
reverse feed applications, the bottom
conductors are the line side with
power flowing through the breaker
from bottom to top. In this case the
trip unit will indicate REVERSE
POWER, but the reading can be
made an absolute value by installing
a jumper from B3 to B7 on the
breaker secondary contacts.

Current Sensor
Toroidally wound current sensors
are installed at the rear of the circuit
breaker on the lower horizontal ter-
minals. They are available in ampere
ratings of 200 through 6300 amperes,
and must match the current rating
of the installed rating plug.
The sensors produce an output current
proportional to the load current.
Under preselected conditions of cur-
rent magnitude and time, the sensors
furnish the trip unit with a signal and
the energy required to open (trip) the
circuit breaker.
The current rating of the installed
sensors can be easily viewed from
the rear of the circuit breaker
through small viewing windows.
The viewing windows are part of the
sensor cover plate which is removed
to change the sensors.
Neutral current sensors are available
for customer installation. The addi-
tional sensor is not supplied with the
circuit breaker and must be ordered
separately. They are wired to the trip
unit through the secondary contacts
on the circuit breaker.
Mechanical Trip Flag Pop-Out
Indicator
The mechanical trip flag pop-out
indicator is an overcurrent indication
feature that can be supplied as an
option on Magnum Circuit Breakers
with integral trip units. This device
is located just above the trip unit on
the breaker’s front faceplate. In the
event the trip unit trips the breaker
on an overcurrent condition, the red
trip flag releases and pops out to
give local visual indication. This
trip indication is in addition to any
LED trip indication provided by the
trip unit.
The red flag can be reset by manually
pushing it back in. The circuit breaker
can be re-closed, even if the flag is
not reset. An optional Overcurrent
Trip Switch (OTS) is available in the
event that an electrical lock-out is
required on an overcurrent trip
condition.
Making Current Release
The Making Current Release (MCR) is
a standard safety feature provided
on all Magnum Circuit Breakers that
are equipped with integral trip units.
The MCR provides an instantaneous
trip when closing on a fault current
which exceeds a specified magnitude.
The MCR is non-adjustable and preset

to trip the breaker when the peak
instantaneous current exceeds 25 x
In (In is established by the breaker’s
current sensors and rating plug).
The MCR is enabled for only the first
two cycles following the circuit
breaker closing operation. When the
MCR trips the breaker, the red trip
flag of the mechanical indicator will
pop out and the red Instantaneous
LED of the trip unit will flash if the
breaker is so equipped.
Bell Alarm/Overcurrent Trip
Switch (OTS)
The Bell Alarm/Overcurrent Trip
Switch (OTS) is an overcurrent indi-
cation feature that can be supplied
as an option on Magnum Circuit
Breakers with integral trip units.
The OTS is physically mounted on
the Mechanical Trip Flag Pop-out
Indicator. The OTS Switch includes
2 Form C contacts that are wired to
the breaker secondary terminals as
shown in the Magnum breaker
connection diagram. These contacts
are available for external wiring to
provide remote trip indication or for
electrical lock-out of a circuit breaker
as required.
In the event the trip unit trips the
breaker on an overcurrent condition,
the red flag of the Mechanical Trip
Flag Pop-ot Indicator releases and
pops out and the OTS contacts
change state. The OTS Switch can
be reset by manually pushing in the
red trip flag. When the trip flag is
reset, the OTS Switch contacts return
to their normal state.
High Instantaneous Trip
Magnum Circuit Breakers that are
rated 100kA and manufactured in the
Standard Frame with 800 to 3200
ampere continuous current ratings
(MWIC08 to MWIC32) are equipped
with a high instantaneous trip. This
instantaneous trip system consists of
small air core sensors (one per
phase) which produce a signal and
transmit it back to the trip unit.
When the fault current approaches
the 85kA withstand rating of the cir-
cuit breaker,
to be closed into repeated overload
conditions, the breaker will trip in
successively shorter times to allow
for the cooling of the load circuit.
When the overload condition returns
to normal, the LTM function begins
to slowly reset and will fully reset
back to the normal Long Delay
Time setting after about 10 minutes,
provided that another overload is not
experienced.
In some applications, for example
fire pump, electric welders or during
primary injection current testing, it
may be desirable to defeat the LTM.
This can be accomplished at the trip
unit by moving a jumper located
inside the cavity behind the test port
cover located at the front of the trip
unit to the Inactive position. The
LTM can be reactivated by returning
the jumper to the Active position.
the trip unit trips the breaker instan-
taneously. This allows the breaker to
be applied on a power distribution
system with a 100kA available fault
current while main-taining selectivity
up to 85kA.
Long Time Memory (LTM)
Long Time Memory (Thermal
Memory) is a standard feature on
Magnum Circuit Breakers supplied
with integral trip units. The thermal
memory function provides overtem-
perature protection on load circuits
against the effects of repeated over-
load conditions. If a breaker is
closed soon after an overload trip
and the current again exceeds the
Long Delay Setting, the LTM reduces
the time to trip to allow for the fact
that the load circuit temperature is
higher than normal due to the previous
overload condition. If the breaker

Over-Temperature Trip
Magnum Circuit Breakers equipped
with integral trip units have an over-
temperature trip function provided as
a standard feature. The over-temper-
ature trip is designed to trip the
breaker when the internal tempera-
ture of the trip unit exceeds 85°C.
This is the approximate manufactur-
er’s published maximum tempera-
ture rating for the trip unit electronic
components. An 85°C temperature
inside the trip unit indicates that
there are much higher temperatures
and potentially significant heating
problems elsewhere on the circuit
breaker.
When the over-temperature function
trips the breaker, the red trip flag of
the mechanical indicator will pop-out
and the red Long Time Delay LED of
the trip unit will flash is the breaker
is so equipped.
Ground Fault Provisions and
Protective Schemes
As a standard feature, Magnum
Circuit Breakers are internally wired
with provisions for ground fault
protection. However, ground fault
protection is provided only if the
breaker is equipped with a trip unit
with optional LSIG protection.
Ground fault protection can be easily
added to breakers not originally
equipped with a ground fault trip
unit. For example, an LSI trip unit
can simply be changed out with a
like model trip unit that has LSIG
protection. Modifications to the circuit
breaker internal wiring are generally
not required as long as the trip unit
changeout is with a like model trip unit.
To provide for maximum application
flexibility, breaker ground fault provi-
sions are wired out to the breaker
secondary terminals for external use.
The secondary terminals can be
easily configured to accommodate
the most common ground fault
schemes, including:
NOTE: For detailed wiring
diagrams that describe all
ground fault sensing options
and wiring connections, refer to
the Trip Unit Instruction Leaflet.
Multiple Source/Multiple Ground
Multiple Source/Multiple Ground
sensing schemes are also possible
on systems with multiple sensors.
Zone Interlocking
Zone Selective Interlocking is a
standard feature provided on
Magnum Circuit Breakers that are
supplied with Digitrip 520i or higher
trip units. The trip unit Short Time
and Ground Fault Time Delay Zone
Interlock function is wired out to
breaker secondary terminals B8 and
B9 for customer use.
The zone interlock function provides
for hard-wired selective circuit breaker
coordination in the power distribution
system. When employed, breaker
secondary terminals B8 and B9 are
connected to establish zones of
downstream and upstream breakers
using 3 wires: Zin, Zout, and a common
wire to establish the zone.
NOTE: For detailed wiring dia-
grams that describe zone selective
interlocking schemes and wiring
connections, refer to the trip
unit instruction leaflet.
In the event that a fault current on
the system exceeds the trip unit
Short Time or Ground Fault pick-up
settings or the Short Delay Setting
2xIr is exceeded, the breaker nearest
to the fault trips instantaneously. At
the same time the trip unit sends a
logic signal to the connected
upstream trip unit to restrain it from
tripping immediately and follow its
protective delay settings. Coordination
is maintained, the breaker closest to
the fault trips first and power is only
selectively disrupted.
NOTE: If zone interlocking is not
employed, it may be defeated
by installing a shorting jumper
across breaker secondary termi-
nals B8 and B9.
Installing a jumper in this manner
defeats the zone interlock function
and tells the trip unit to follow its set
Short Time and Ground Fault Time
protective delays. If breaker sec-
ondary terminals B8 and B9 are left
as open circuit, the trip unit Short
Time and Ground Fault Time Delay
functions will trip instantaneously if
the system fault current exceeds the
pick up setting.
Residual Sensing
Residual sensing is the standard or
default wiring configurations provided.
It is also the most common mode of
ground fault sensing used in 3-pole
and 4-pole breaker applications. One
current sensor per pole on each
phase conductor is provided internal
to the circuit breaker. When 3-pole
breakers are applied on 3 phase, 4
wire systems, an external sensor
matched to the breaker sensor ratio
is mounted on the Switchgear neutral
bus and wired to the breaker secondary
contacts to connect all sensors in the
residual circuit.
Source Ground Sensing
Source ground sensing is commonly
found on 3 pole breakers applied as
a main breaker on single-ended radial
or on double-ended systems where
a mid-point grounding electrode is
employed.
To configure a breaker for source
ground sensing, a shorting jumper is
applied to breaker secondary contacts
B6 and B7 to defeat the residual
sensing mode. An external current
sensor is mounted directly on the
bonding conductor to ground to
measure the ground current flowing
in the grounding electrode conductor
and all other grounding conductors.
The sensor is then wired to the breaker
secondary contacts B4 and B5.
NOTE: The secondary current
rating of the sensors must be 1
ampere.
Zero Sequence Sensing
Zero sequence sensing is applied on
main and feeder breakers, and other
breakers employed in zone interlocking
ground protection schemes.
To configure a breaker for zero
sequence sensing, a shorting jumper
is applied to breaker secondary con-
tacts B6 and B7 to defeat the residual
sensing mode. Zero sequence sensors
with 1000:1 and 100:1 ratios are
available for mounting in the
switchgear cable compartment. The
sensor internal window dimensions
are 114 x 342 mm (4.5 x 13.5 inches)
for accommodating power cables.
The zero sequence sensors are wired
to breaker secondary contacts B4
and B5.

Fixed Mounted Circuit Breakers
Magnum fixed mounted circuit
breakers are commonly applied in
specialty power distribution enclo-
sures and switchboards manufac-
tured by Low Voltage Power
Assemblers.
The fixed circuit breaker construction
is simple and economic because
there are no drawout system compo-
nents. The breaker bolts directly to
the enclosure main bus, which
allows for efficient current transfer
under loaded conditions. This
improves thermal management and
provides for the design of compact
enclosures with shallow depth.
Full visual and physical access to the
circuit breaker trip unit, controls, and
indicators is available through the
compartment front panel. A door
frame and escutcheon kit is available
as an option to provide a finished
trim to the front panel cutout.
Extensive accessorization capability
of the breaker is retained, including
trip units, internal accessories, lock-off
devices, and mechanical interlocks.
Primary Terminations
Horizontal pre-drilled terminal pads
are provided as a standard feature
for use in terminating the breaker to
the enclosure bus. Optional vertical
adapters can be factory installed or
are available as field option kits to
provide the capability to terminate
the enclosure bus in the vertical
plane. Field option kits are also
available for front connected
applications.
If the benefit of front accessible
dedicated terminal blocks at the top
front of the breaker is desired, the
terminal block mounting bracket
included in the secondary connection
terminal kit can be used. Catalog
Number MSECBK white terminal block
kits can be purchased and assembled
to the mounting bracket. Catalog
Number MSECWR wire kits can be
purchased to connect the white
terminal block to the black AMP
connector block points.
Mounting Feet
Metal mounting feet are provided as
a standard feature for use in securely
bolting the breaker to the enclosure.
Secondary Connections
Two black 30-pin AMP connector
blocks are located at the top front of
the breaker to receive up to 60 points
of external secondary wiring. A
secondary connection terminal kit is
included with each fixed breaker to
provide for several wiring options.
The most economic solution is to
terminate external wiring directly to
the black AMP connector blocks.
Catalog Number MWK40 wire bundle
kits with 30 wires 40 inches long can
be purchased for this purpose. The
wire bundles can also be self-fabricated
by the enclosure manufacturer,
provided the proper AMP terminal
and crimping tool are used.

37Drawout Circuit Breakers
May 2003
PG01301002E
Drawout Circuit Breakers
Magnum drawout circuit breakers
are commonly applied in specialty
power distribution enclosures,
switchgear and switchboards manu-
factured by Low Voltage Panel
Assemblers.
The Magnum drawout circuit breaker
construction is a through-the-door
design. Full visual and physical
access to the trip unit and all breaker
controls and indicators is available
through the compartment front
panel. For maximum safety, circuit
breaker levering can be performed
with the compartment door closed.
When the circuit breaker is in the
OPEN position, a padlockable access
door can be raised to receive the
levering device. No special device is
required. Levering can be accom-
plished with a common 10 mm size
square drive and rachet. When
inserted, the levering device holds
the levering access door open. As
long as the access door is raised
open, the breaker is held in the “trip-
free” condition. The breaker can be
levered to three positions in the cell
compartment. Colour coded position
indicators are provided on the breaker
front panel to provide positive indi-
cation of each position:
Green = DISCONNECT
Yellow = TEST
Red = CONNECT.
Secondary Disconnect Contacts
The breaker secondary disconnecting
contacts engage or disconnect with
the cassette secondary contacts as
the breaker is levered into or out of
the TEST position.
Primary Disconnecting Contacts
The primary disconnecting contacts
(finger clusters) engage or disconnect
with the cell compartment bus stabs
as the breaker is levered into or out
of the CONNECT position.
The primary disconnecting contacts
are mounted on the rear of the
breaker so that they can be easily
inspected or replaced. All breaker
frames have horizontal primary dis-
connects.

Drawout Cassette
A drawout circuit breaker is used in
combination with a fixed drawout
cassette. The cassette provides for
all the required fixed drawout features
as well as fixed primary and secondary
connections. Mounting locations for
cell (TOC) switches, primary safety
shutters and various key interlocks
are part of the cassette design.
The cassette has built in horizontal
stabs and primary terminals.
Optional bolt-on 90 degree adapters
are available to rotate the primary
terminals on the rear of the cassette to
a vertical orientation; these can be
used on either the line, load or both
primary connection.
It should be noted that short circuit
currents create very large electro-mag-
netic forces on the bus bars which
must be adequately supported by the
assembly builder. Outline drawings
for each cassette give minimum dis-
tances from the rear of the cassette
wherein adequate bus bar supports
must be provided. The design of
these supports depends upon the bus
bar configuration and short circuit rat-
ing and is the responsibility of the
assembly builder.

The cassette's drawout extension
rails can be padlocked to prevent a
circuit breaker from being inserted
during maintenance periods. In
addition, the cassette includes all
required safety interlocks which
function with the circuit breaker's
interlock system to insure safe
operation.
An arc hood is positioned above
where the circuit breaker's arc chutes
will be allowing for zero clearance
mounting when vertically stacked in
an assembly. Mounting holes are
provided at the rear and in the floor
of the cassette for secure mounting
in an assembly.

39Phasing on Double-Wide Breakers
May 2003
PG01301002E
Phasing on Double-Wide Frame
Breakers
Magnum circuit breakers manufac-
tured in the double-wide frame have
two available phasing configurations
which must be confirmed when the
breaker is ordered.
The phasing convention is determined
facing the front of the breaker from
left to right. For 4-pole applications,
the neutral is located on the left and
is rated 100% of the breaker continuous
current rating. The following phasing
configurations are available:
3-Pole AABBCC
4-Pole NNAABBCC
3-Pole ABCABC
4-Pole NNABCABC
The type of phasing selected
depends on how the circuit breaker
will be applied in the enclosure and
the type of Cutler-Hammer power
distribution enclosure that it will be
applied in.
AABBCC or NNAABBCC Phasing
AABBCC phasing is the convention
commonly used in IEC Switchboards
using Magnum Circuit Breakers.
The AABBCC convention is recom-
mended for most switchgear assembler
manufacturing their own power
distribution enclosures. It is ideal for
applications where the breaker is
mounted single high (one breaker in
a structure).
ABCABC or NNAABCABC
Phasing
ABCABC phasing is available, but not
common in IEC Switchgear
Applications. Contact Cutler-
Hammer for more information.

Accessory Devices
A variety of accessory devices are
available for use with Magnum circuit
breakers. Unless otherwise stated,
they are all considered optional
devices in the sense that they are not
provided as standard on a manually
operated circuit breaker. Available
accessories are identified here and
discussed in general terms. For
more detailed information and/or
installation instructions, refer to indi-
vidual instruction leaflets dedicated
to the accessories.
Magnum circuit breaker accessories
are designed to fit all frame sizes.
The accessories fall into one of three
categories:
• Plug-in electrical
• Internal electrical
• Mechanical
Plug-In Electrical Accessories
There are four Magnum Plug-In
electrical accessories. Three can be
viewed for identification by name
and rating through viewing windows
located in the right front of the circuit
breaker(Figure 1). All four are plug-in
type and can be factory installed or
field installed.
The four Plug-In accessories are:
• Shunt Trip (ST)
• Spring Release (SR)
• Undervoltage Release (UVR)
• Auxiliary Switch
Shunt Trip (ST) - The ST (Shunt
Trip Device, Figures 2and 3) is an
optional accessory device that is
mounted internal to the circuit break-
er. The ST acts to electrically open
the circuit breaker when its trip coil
is energized by a rated trip voltage
signal (Table 1) that is applied
through the breaker secondary con-
tacts, typically by a control switch or
other similar device. The ST has a
dedicated auxiliary switch with con-
tacts that change state as the breaker
opens, cutting off trip voltage signal
to the trip coil.
A second shunt trip (with the same
or different control voltage) can be
mounted in the same space as the
Undervoltage Release (UVR). When
a second shunt trip is used, one of
the auxiliary switch stages must be
used to provide the trip coil cut off
contact.

Spring Release (SR) - The SR
(Spring Release Device, Figure 4) is
an optional accessory device that is
mounted internal to the circuit break-
er. The SR acts to electrically close
the circuit breaker when its close coil
is energized by a rated close voltage
signal (Table 2) applied through the
breaker secondary contacts, typically
by a control switch or other similar
device.
The breaker must be ready to close
for the SR to close the circuit breaker.
The breaker stored energy springs
must be fully charged and the trip
latch must be in the reset (not the
trip) position. If the close voltage
signal is applied before these two
conditions are met, the SR will not
close the circuit breaker. The close
voltage signal must be removed and
then reapplied at a time when the
breaker is ready to close.
•Latch Check Switch Wired For
External Use - The LCS can also
be wired to the breaker secondary
contacts. One Form C contact is
provided for remote indication that
the breaker is ready to close for
use in breaker external customer
control wiring.
Undervoltage Release - The under-
voltage release is an optional device
on both manually and electrically
operated circuit breakers (Figure 5).
It opens the circuit breaker when its
supply voltage falls to between 35-
60% of rated voltage. If the release
is not energized to 85% of its supply
voltage, the circuit breaker cannot
be closed electrically or manually
(Table 3).
Latch Check Switch (LCS) - The
LCS (Latch Check Switch) is an
optional accessory switch mounted
internal to the circuit breaker that
changes state when the breaker is
ready to close (the closing springs
are fully charged and trip latch is in
the reset position). The LCS is very
useful in fast transfer and automatic
transfer applications when it is
important that the breaker responds
to close on a single close voltage sig-
nal of rated magnitude. The LCS is
available in two versions:
•Latch Check Switch Wired To
Spring Release - The LCS can be
wired directly to the Spring
Release Device to provide a con-
tact closure when the breaker is
ready to close. This delays the
voltage signal to the Spring
Release until the breaker is ready
to close.

Internal Electrical Accessories
Other electrical accessories are
mounted inside the circuit breaker.
They can be factory or site installed.
There are two different internally
mounted accessories:
• Overcurrent Trip Switch (Bell
Alarm)
• Motor Operator
Overcurrent Trip Switch (Bell
Alarm) - An overcurrent trip switch
(bell alarm) is an optional device
(Figure 8). It provides an electrical
indication when a circuit breaker trips
as a result of the trip unit reacting to
an overcurrent condition. Opening as
a result of a circuit breaker’s manual
open button, shunt trip or undervoltage
release does not cause the overcurrent
trip switch to operate. The overcurrent
trip switch has (2a 2b) Form C contacts
(Table 4).
The status of the contacts
changes when the trip indicator pops
out. This permits the
switch to be used as an alarm
or in conjunction with a spring
release to block a subsequent remote
electrical closing signal.

Auxiliary Switch - An auxiliary
switch is an optional accessory
device that is mounted internal to the
circuit breaker. Each auxiliary switch
stage (Figure 6) has 2a (normally
open) and 2b (normally closed) con-
tacts wired to the breaker secondary
contacts for customer use in remote
indication or external electrical
schemes. (See Table 4for auxiliary
switch contact ratings.) The contacts
change state as the breaker opens
and closes.
A maximum of 3 switch stages of
2a/2b contacts can be mounted in
Magnum Standard and Double
Frame Circuit Breakers for a total of
6a and 6b available contacts. If more
than two switch stages are required
on the Narrow Frame Breaker, refer
the application to Cutler-Hammer.
Due to the 48 point secondary termi-
nal block limitation on the Narrow
Frame Breaker, only 2 stages of 2a/2b
contacts can be mounted if the full
compliment of breaker internal
accessories are employed. However,
if the breaker is not fully acces-
sorized, the Narrow Frame Breaker
can accommodate 3 auxiliary switch
stages of 2a/2b contacts.

Mechanical Interlock - A family of
mechanical interlocks are available to
interlock the closing of two or three
Magnum circuit breakers. The
mechanical interlock holds one or
more circuit breakers tripped (prevents
closure) when others are closed. A
lever assembly is mounted on each
breaker which interfaces with the
pole shaft and the tripper bar. The
lever assemblies are interconnected
with either cables or rods, depending
upon the relative orientation of the
breakers. Rods can be used only
when the circuit breakers to be inter-
locked are vertically stacked. Cables
can be used for any orientation of
the breakers. Mechanical interlocks
are available for both fixed and drawout
circuit breakers and in both 2-way
and 3-way versions. An illustration
of a 2-way cable interlock mounted
on two drawout circuit breakers is
shown in Figure 18. In addition,

Breaker Lock OFF Devices
Magnum DS Circuit Breakers are
equipped with a variety of lock
off devices for both the Circuit
Breaker and the Drawout Cassette to
maximize safety during equipment
operation and maintenance.
Padlockable Levering Device
Access Door - The levering Device
access door includes padlock provi-
sions as a standard feature on all
drawout circuit breakers. It is
designed to receive a padlock up to
8 mm (0.312 inches) in diameter.
When the access door is padlocked
shut, the breaker levering tool cannot
be inserted, preventing the breaker
from being levered to another
position (Figure 1).
Access Door - The padlockable
pushbutton cover is an optional
factory configured or field option kit
accessory that mounts on the breaker
faceplate. It is available with either
molded plastic or metal frames with
clear plastic hinged blocking plates
(Figure 2). When they are closed
and padlocked, the blocking plates
prevent access to the breaker PUSH
OFF and PUSH ON mechanical push-
buttons. This device can also be
configured with an additional plate to
block only the PUSH ON pushbutton.
A small hole is pre-drilled in the
blocking plates to provide emergency
access with a special tool as required
per the National Electric Code. The
padlockable pushbutton cover will
receive a padlock with up to a 8 mm
(0.312 inches) diameter.
Cassette Lock Provisions - The
cassette lock provisions field option
kit is an accessory that mounts on
the side of a circuit breaker cassette
(Figure 4). The customer must specify
if the lock is to be located on the left
or right-hand side of the cassette.
When installed, the device holds the
breaker trip-free when the breaker is
levered to the CONNECTED position.
This prevents the breaker from being
closed and circuit energized.
Single or multiple cylinder Kirk,
Castell or Ronis locks can be accom-
modated. The device can be used
with commonly applied breaker
interlocking schemes such as
Main-Tie-Main configurations, etc.
Breaker OFF Key Lock Provisions
-The breaker OFF key lock is an
optional accessory that allows the
breaker to be locked in the OFF posi-
tion with the key removed, prevent-
ing the breaker from being closed. It
is primarily intended for use on fixed
mounted circuit breakers, but can
also be applied on drawout breakers
(Figure 3).
When selected as a factory configured
option, the breaker includes a pre-
drilled hole covered with a plastic
cap on the breaker front cover. A
lock provisions hardware kit is
shipped with the breaker to facilitate
installation of a single Kirk, Castell
or Ronis cylinder lock. The cylinder
lock is generally provided and
assembled to the breaker at the point
of use by the enclosure manufacturer
or customer. For existing breakers,
a breaker key lock provisions field
option kit is also available. To facilitate
installation, a drill point mark is
located on the inside of the breaker
front cover to identify the drilling
location for the key lock installation.

Ambient Temperature
This table gives derating factors for
circuit breakers operating in switch-
boards at various internal ambient
temperatures. The switchboard’s
internal ambient should be estimated
using the calculation methods of IEC
890, 1997 or an equivalent method.
Bus Bar Recommendations
The bus bar sizes shown in the table
are those specified in IEC 947-1
and/or used by Cutler-Hammer in
their circuit breaker type testing.
They are for 3 meter long bus bar
with the faces vertical and painted
flat black. For other bus bar configu-
rations, larger bus bar sizes may be
required or the circuit breaker may
have to be derated. Refer to the
table in this section entitled “Circuit
Breaker Continuous Current Ratings
at Different Ambients” for derating
information at higher ambient tem-
peratures. Refer to the two graphic
examples below.

Factory Configured Circuit
Breakers
Magnum Air Circuit Breakers are
ordered using a 25-digit catalog
numbering system that allows for
maximum options and flexibility.
Circuit breaker configuration is
achieved by using a simple 2-step
process.
Note: If the breaker is drawout
construction and a cassette is
required, the cassette must be
configured separately.
Step 1: Select a 10-Digit Breaker
Catalog Number Prefix.
Choose the breaker prefix from
Tables 5.1, 5.2, 5.3 or 5.4 based
on the following:
■Drawout of Fixed Construction
■Number of Poles
■Continuous Current Rating
■Magnum Frame Type
■Interrupting Rating
■Short Time Withstand
■Phasing (Double-wides only)
■Catalog Position 20 establishes
if an optional OTS/Bell Alarm Switch
and/or a Mechanical Trip Indicator is
installed per Table 3.14.
■Catalog Position 21 establishes
if an optional Padlockable
Pushbutton Cover is installed per
Table 5.15.
■Catalog Position 22 establishes
if an optional Key Interlock Provision
is installed per Table 5.16.
■Catalog Position 23 establishes
if an optional Latch Check Switch is
installed per Table 5.17 and/or
designates the voltage connection if
an 1150 Trip Unit is supplied.
■Catalog Position 24 establishes
if the breaker is shipped alone or in a
cassette with options per Table
5.18.
■Catalog Position 25 is reserved
for Cutler-Hammer use per Table
5.19.
Step 2: Select Breaker Catalog
Positions 11 through 25 to
designate factory installed
options as follows:
■Catalog Positions 11 and 12
establish the sensor and rating plug
ratings per Tables 5.5, 5.6
and 5.7.
■Catalog Positions 13 and 14
establish the trip unit type per Table
5.8.
■Catalog Position 15 establishes
if an optional Shunt Trip is installed
per Table 5.9.
■Catalog Position 16 establishes
if an optional Motor Operator is
installed per Table 5.10.
■Catalog Position 17 establishes
if an optional Spring Release Device
is installed per Table 5.11.
■Catalog Position 18 establishes
if an optional Undervoltage Release
or Second Shunt Trip is installed per
Table 5.12.
■Catalog Position 19 establishes
if optional Auxiliary Switches are
installed per Table 5.13.
