Magnum DS
The New Standard in Low Voltage Power Circuit Breakers
Cutler-Hammer Type DS Low
Voltage Power Circuit Breakers
have set the industry standard for
over three decades. When reliability and customer service are
paramount, Cutler-Hammer is the
market leader for ANSI/UL applications

A compact and modular family

of breaker frame sizes makes the
design of compact, economical
and versatile enclosures a reality.

Field installable accessories

minimize inventory and permit ULapproved field installation of current sensors, rating plugs, trip units
and accessories.

There is a new generation of CutlerHammer Power Circuit Breakers

that are smaller with higher performance and more versatility.

Magnum DS
Magnum DS Low Voltage Power
Circuit Breakers are designed for
ultimate application flexibility,
with the needs of both the power
distribution equipment user and
the low voltage electrical equipment manufacturer in mind.
For maximum safety, a modern,
through-the-door design permits
access to the breaker levering system, trip unit, controls, and indicators with the door closed.
High withstand and interrupting
ratings provide for maximum selectivity and system coordination to
meet the needs of the high available fault currents on todays electrical power distribution systems.

One Family
July 2003

Three Frame Sizes in One Family

Magnum DS circuit breakers are
available in a family of three
physical frame sizes.

The MDN narrow frame is the

highest performing power circuit
breaker of its size and rating class.
Continuous current ratings are
available from 800 to 1600
amperes (drawout) and 800 to 2000
amperes (fixed mounted).
Withstand and interrupting ratings
are available from 42 to 65 kA at
600Vac. The MDN compact size
allows for application in compact
enclosures of many types.

The MDS standard frame is ideally suited for the construction of vertically stacked modular ANSI/UL
Switchgear and Switchboards.
Continuous current ratings are
available from 800 to 3200 amperes
in the same frame with uniform 5
inch pole center spacing.
Withstand ratings are available to
85 kA and interrupting ratings to
100 kA at 600 Vac for improved system coordination and service continuity.

The MDS 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
and 5000 amperes. A 6000 rating is
available when the breaker is
applied in a suitably designed and
tested fan cooled enclosure.
Withstand and interrupting ratings
are available to 100 kA at 600Vac
for maximum system coordination
with down stream devices.

Smaller Size
July 2003

More Circuit Breakers

per
Square Foot of Space
The Magnum DS circuit breaker is
significantly smaller than previous generation open type metal
frame power circuit breakers. High
strength, thermoset composite
resin materials used in the breaker
frame provide increased strength
for higher capacity ratings. This
leads to the design of smaller and
more economic enclosures
using far less critical floor
space.
The modern, through-the-door
design construction results in
enclosures of shallower depth,
while providing three position drawout levering and storage with the
enclosure door closed.
The modular design of the
Magnum DS standard and doublewide frames is the key to design
simplification and more compact
Switchgear. Two columns of single-wide circuit breakers can be
stacked over or under double-wide
breakers with a common riser bus.

Higher Performance

July 2003

Higher Levels of Performance

Magnum DS circuit breakers have
higher levels of performance
than conventional metal frame
power circuit breakers.

Higher interrupting capacity

allows Magnum DS to be applied
on power distribution systems with
higher available fault currents.
Higher short time (withstand)
current ratings along with selective
(LS) Digitrip RMS trip units results
in improved selectivity between
main, feeder, and branch circuit
breakers.

Design and Testing Standards

July 2003

Introduction
The Magnum DS power circuit
breaker was designed and tested to
meet the requirements of the ANSI
market. It is a 100% rated device,
designed to carry 100% of its
nameplate current rating in an
enclosure without derating.
Magnum DS circuit breakers are UL
Listed, and tested to all applicable
NEMA, ANSI, IEEE and UL standards.
Specifically, the circuit breakers
comply with the following:

ANSI C37.13 (Low Voltage AC

Power Circuit Breakers Used In
Enclosures)
ANSI C37.16 (Preferred Ratings,
Related Requirements And
Application Recommendations
For Low Voltage Power Circuit
Breakers And AC Power Circuit
Protectors)
ANSI C37.17 (Trip Devices For AC
And General Purpose DC Low
Voltage Power Circuit Breakers)
ANSI C37.50 (Test Procedures
For Low Voltage AC Power
Circuit Breakers Used In
Enclosures)

PG01301001E

UL 1066 (Standard For Low

Voltage AC And DC Power Circuit
Breakers Used In Enclosures)
NEMA SG3 (This Standard
Adopts ANSI C37.16 In Its
Entirety)

In addition, Magnum DS is suitable

for use in:

UL 1558 LV Switchgear
UL 891 LV Switchboards
UL CSA 22.2.31 LV Assemblies

Magnum DS circuit breakers can be

used in forward or reverse feed
applications.
The standards outlined establish
the minimum requirements. There
is nothing prohibiting a circuit
breaker design from exceeding
standards by offering additional
features and/or higher levels of performance. Magnum DS does this
in a number of areas.

ANSI 37.50 Testing

Low voltage power circuit breakers
can be applied at or below their
nameplate rating. That nameplate
rating is a result of having successfully completed a series of rigrous
tests. This is the 100% rating.

For more information visit: www.cutler-hammer.eaton.com

ANSI C37.50 testing is demanding

and consists of four test sequences.
All tests are performed using a
drawout circuit breaker in its minimum size enclosure for each frame
size. The first three tests are similar
in a number of ways to tests performed on other types of low voltage circuit breakers, such as molded
case circuit breakers. It is the
fourth test sequence that differentiates the power circuit breaker from
other circuit breakers.

Test Sequence 1
This test sequence consists of a
temperature rise test, an overload
calibration, and then a short circuit
test.
Test Sequence 2
This test sequence consists of a
series of short circuit tests.
Test Sequence 3
This test sequence is a test of
endurance.
Test Sequence 4
This test sequence is a momentary
rating test. Other types of low voltage circuit breakers are not subjected to this type of test and, therefore,
have no full 30 cycle short time rating.

Summary
Rigid Frame Housing
Magnum DS circuit breakers use a
rigid frame housing construction of
engineered 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:

A 2-piece case encloses current

paths and arc chambers. The
chambers act to channel arc gases
up and out during interruption.

The operating mechanism and

accessories sit on the front of the

case and are covered by an insulating front cover. Only the cover
needs to be removed to access the
mechanism or add accessories.

lable accessory items can be identified by name and rating through

viewing windows. An optional
padlockable cover limits access to
the ON and OFF pushbuttons.
Complete access to the ON pushbutton can be prevented with an
optional prevent close cover.

The overall strength and rigidity of

the design also contributes to higher performance capabilities:

Higher Withstand
Higher Interrupting

Magnum DS Rigid Frame Construction

The Magnum DS 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.

2-Step Stored Energy

Mechanism
Magnum DS circuit breakers are
equipped with a 2-step stored energy mechanism. The mechanism
closing springs can be charged
manually or electrically, providing
the stored energy to CLOSE the
breaker. After the breaker is closed,
the mechanism closing springs can
again be charged and the stored
energy mechanism allows the
breaker to OPEN CLOSE OPEN
without performing another charging operation.

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.
The braided connectors (flexible
shunts) used to attach each contact
finger serve several important purposes:

Main Contact System

Single Contact Finger
The performance characteristics of
the Magnum DS 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

hot spots
Reduce required mounting space
for primary contacts

Heel - Toe rocking

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 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
permits 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:

Heel-Toe Action
The Heel-Toe movement of the
contact fingers is a critical factor in
the efficiency of the Magnum DS

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.

Magnum DS Circuit Breaker Being Manually Charged

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.

Motor Operator Installed

An optional motor operator is used

to charge the closing spring automatically. It can be field installed in
a manually operated circuit breaker.
Manual circuit breakers are prewired for this addition.

Electrical Operation
The closing spring is charged automatically 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 antipump feature, an open circuit breaker
only accepts one attempt to reclose
even if the close command continues,
preventing motor operator burnout.

Motor Operator

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
provide reliable low impedance
connections for up to 60 terminal
points of breaker control wiring.
The secondary 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 manufacturing. Labels are
provided on the blocks to assist the
customer in terminal 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 extraction tool
(AMP part number 305183).

Secondary Terminal Blocks

(White)
White secondary terminal blocks
can be provided mounted at the top
front of the breaker for customer
use. The 6-point terminal blocks
have hinged IP20 finger-proof covers and are designed to terminate
various customer wire terminals
including ring type terminals. Up

Digitrip RMS
Trip Unit Summary
Magnum circuit breakers can use

The trip units themselves are self

powered; no external power is
required to operate the protective
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.

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.
Magnum Hand Held Tester

Common Features
All trip units have a green light
emitting 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.

Rating Plugs
All Magnum DS circuit breaker trip
units use a fixed type rating plug.
Rating plugs are available in
ampere ratings of 200 through 6000
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:

Trip units are interchangeable in

the field, except for Model 520MC
and Model 1150. Contact CutlerHammer for interchangeability
details.

A functional local test of a major

portion of every trip units electronic circuitry and the circuit breakers
mechanical tripping action can be
verified through the trip units 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.

PG01301001E

Rating Plug Installed in Digitrip 1150

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
instantaneous 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 units 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.

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 conductors, 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

Note: Refer to Tables 3.4, 3.5 and 3.6 in the

section entitled Circuit Breaker Catalog
Number for the availability of sensor and rating plug ratings for specific circuit breaker
frame sizes.

The sensors produce an output current proportional to the load current. Under preselected conditions
of current 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.

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 DS Circuit
Breakers with integral trip units.
This device is located just above
the trip unit on the breakers 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.

Neutral Sensor (unmounted)

Neutral current sensors are available

for customer installation. The additional 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.

Making Current Release

The Making Current Release (MCR)
is a standard safety feature provided on all Magnum DS 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, preset

will flash if the breaker is so
equipped.

Bell Alarm/Overcurrent Trip

Switch (OTS)
The Bell Alarm/Overcurrent Trip
Switch (OTS) is an overcurrent indication feature that can be supplied
as an option on Magnum DS 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 DS 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 DS Circuit Breakers that
are rated 100kA and manufactured
in the Standard Frame with 800 to
3200 ampere continuous current
ratings (MDSC08 to MDSC32) 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 circuit breaker,

the trip unit trips the breaker

instantaneously. This allows the
breaker to be applied on a power
distribution system with a 100kA
available fault current while maintaining selectivity up to 85kA.

Long Time Memory (LTM)

Long Time Memory (Thermal
Memory) is a standard feature on
Magnum DS Circuit Breakers supplied with integral trip units. The
thermal memory function provides
overtemperature protection on load
circuits against the effects of
repeated overload 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 continues

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 pumps, electric welders or during primary injection current testing, it may be desirable to defeat
the LTM. This can be accomplished
at the trip unitby 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.

Trip Units and Communications

July 2003

Over-Temperature Trip
Magnum DS Circuit Breakers
equipped with integral trip units
have an over-temperature trip function provided as a standard feature.
The over-temperature trip is
designed to trip the breaker when
the internal temperature of the trip
unit exceeds 85C. This is the
approximate manufacturers published maximum temperature rating for the trip unit electronic components. An 85C temperature
inside the trip unit indicates that
there are much higher temperatures and potentially significant
heating problems elsewhere in the
circuit breaker enclosure.
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
DS 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
provisions 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.

Residual Sensing
Residual sensing is the standard or
PG01301001E

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.

Multiple Source/Multiple
Ground
Multiple Source/Multiple Ground
sensing schemes are also possible
on systems with multiple sensors.

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.

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.

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 contacts 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 4.5 x 13.5
inches (114 x 342 mm) for accommodating power cables. The zero
sequence sensors are wired to
breaker secondary contacts B4 and
B5.

Zone Interlocking
Zone Selective Interlocking is a
standard feature provided on
Magnum DS Circuit Breakers that
are supplied with Digitrip 520 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.

NOTE: For detailed wiring diagrams 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 terminals 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
secondary 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.

Fixed Circuit Breakers

July 2003

Fixed Mounted Circuit Breakers

Magnum DS fixed mounted circuit
breakers are commonly applied in
Cutler-Hammer Pow-R-Line C
UL891 certified switchboards and
other specialty power distribution
enclosures and switchboards manufactured by OEMs.

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.

The fixed circuit breaker construction is simple and economic

because there are no drawout system components. 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.

If the benefit of front accessible

dedicated terminal blocks at the top

July 2003

Drawout Circuit Breakers

Magnum DS drawout circuit breakers are commonly applied in CutlerHammer Magnum DS UL1558 certified switchgear and other specialty
power distribution enclosures,
switchgear and switchboards manufactured by OEMs.

The primary disconnecting contacts are mounted on the rear of

the breaker so that they can be easily inspected or replaced. Standard

and Double frame breakers have

vertical primary disconnects, while
Narrow frame breakers have horizontal primary disconnects.

Circuit Breaker Being Levered

The Magnum DS drawout circuit

breaker construction is a throughthe-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 accomplished with a common 3/8 inch
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. Color coded
position indicators are provided on
the breaker front panel to provide
positive indication of each position:

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.
Cutler-Hammer offers several drawout cassette options. The narrow frame circuit breaker
mates only with the Narrow
cassette which 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 connections.
Standard frame circuit breakers also offer two optional drawout cassettes. Both use vertical
stabs internal to the cassette. The
Universal cassette offers a flat
terminal pad on the rear of the cassette which will accept customer
bus bar connections in various bent
configurations; optional T-bar
adapters are available which can be
rotated to give either vertical or
horizontal terminals. The Basic
cassette has a molded back plane
with vertical aperturers that can be
used when the bus bar connections
will remain vertical. The OEM can
simply continue bus bar through
the openings in the back plane to
form stabs for the circuit breaker.
Note that these stabs must be silver-plated. Optionally, CutlerHammer will supply short straight
pieces which are pre-plated, and
will bolt into the back plane to
accept bolted bus bar connections.

Narrow Frame Breaker and Cassette

supports must be provided. The

design of these supports depends
upon the bus bar configuration and
short circuit rating 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.

Phasing on Double-Wide Breakers

July 2003

Phasing on Double-Wide Frame

Breakers
Magnum DS circuit breakers manufactured in the double-wide frame
have two available phasing configurations which must be confirmed
when the breaker is ordered.

Magnum DS Double-Wide Frame Breaker with AABBCC Phasing (front and rear views)

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 Cutler-Hammer
Pow-R-Line C Switchboards using
Magnum DS Circuit Breakers.
The AABBCC convention is recommended for most OEMs 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 NNABCABC
Phasing
ABCABC phasing is the convention
commonly used in Cutler-Hammer
Magnum DS UL1558 Switchgear.
Double-wide breakers with this
type of phasing are designed to
accommodate 2 sets of vertical risers in the same structure. This provides for significant space savings
because two or more standard
frame feeder breakers can be
mounted above or below the dou

PG01301001E

ble-wide breaker in the same structure.

Cutler-Hammer offers Magnum DS
Switchgear power modules with
ABCABC phasing for use by OEMs.
Power Modules provide the OEM
with a shell frame assembly,
which allows for substantial modification. Power Modules consist of
base metal structures, compartment cells and vertical bus.
Typically the OEM will provide the

value add to customize the power

modules into their own switchgear
design.
The ABCABC convention is more
difficult for OEMs who manufacture
their own power distribution enclosures to apply. Switchgear bus
design and testing as well as placement and balance of the feeder
breaker loads are very important to
assure that phase currents divide
evenly through the double-wide
breaker.

Accessory Devices
A variety of accessory devices are
available for use with Magnum DS
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 individual
instruction leaflets dedicated to the
accessories.
Magnum DS 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 DS 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
using a UL listed kit.

Accessory Viewing Windows

Figure 1 Through-the-Window Electrical Accessories

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.

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 2 and 3) is an
optional accessory device that is
mounted internal to the circuit
breaker. 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 contacts, typically by a control switch or other similar device.
The ST has a dedicated auxiliary
switch with contacts that change
state as the breaker opens, cutting
off trip voltage signal to the trip
coil.

Spring Release (SR) - The SR

(Spring Release Device, Figure 4) is
an optional accessory device that is
mounted internal to the circuit
breaker. 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.

Figure 4 Spring Release with

Optional Latch Switch

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 signal 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 contact closure when the breaker is
ready to close. This delays the
voltage signal to the Spring
Release until the breaker is ready
to close.

Figure 5 Undervoltage Release

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
undervoltage 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).

Auxiliary Switch - An auxiliary

switch is an optional accessory
device that is mounted internal to
the circuit breaker. Each auxiliary
switch stage (Figure 7) has 2a (normally open) and 2b (normally
closed) contacts wired to the breaker secondary contacts for customer
use in remote indication or external
electrical schemes. (See Table 4
for 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 terminal 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
accessorized, the Narrow Frame
Breaker can accommodate 3 auxiliary switch stages of 2a/2b contacts.

PG01301001E

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 breakers 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 change
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.

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 interlocked
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 2way and 3-way versions. An illustration of a 2-way cable interlock

July 2003

Suggested Tools
Maintenance Overview
General Cleaning
When to Inspect
What to Inspect

Suggested Tools
A large number of different tools
are not required to maintain
Magnum DS circuit breakers. The
following tools are suggested:
Flat blade screw driver
Phillips head screw driver
3/8 socket (rachet) wrench
6 socket extension with 3/8
square drive
10mm socket
17mm socket
Secondary wiring removal tool

Maintenance Overview
Design tests and actual installation
experience shows the Magnum DS
low voltage circuit breaker to have
durability well beyond minimum
standards requirements. However,
because of the variability of application conditions, inspection and
maintenance activities should take
place on a regularly scheduled
basis.
These circuit breakers are designed
to be relatively maintenance free.
The maintenance consists mainly
of keeping them clean. Cleaning
and preventive measures are part
of any good maintenance program.
Plant operating and local conditions can vary to such an extent
that the actual schedule should be
tailored to the conditions.
Maintenance record sheets should
be completed each time maintenance is performed. Careful and
accurate documentation of maintenance activities provides a valuable
historical reference on equipment
condition over time.
General Cleaning
Circuit breaker cleaning should be
part of an overall maintenance program that includes the assembly in
which the circuit breaker is
PG01301001E

installed. Loose dust and dirt

should be removed from external
surfaces using an industrial quality
vacuum cleaner and/or lint free
cloth. Unless otherwise indicated,
never use high pressure blowing
air, since dirt or foreign objects can
be driven into areas, such as the
operating mechanism. Never use a
wire brush to clean any part of the
circuit breaker.
When to inspect
Do not wait for specific scheduled
periods to visually inspect the
equipment, if there are earlier
opportunities. For this type of
equipment, it is recommended that
a general inspection and lubrication take place after the number of
operations listed in the Inspection
Frequency table. This type of
general inspection should also take
place at the end of the first six
months of service, even if the number of operations indicated in the
table has not been reached.
After the first inspection, inspect at
least once a year. If these recommended inspections show no maintenance requirements, the period
can be extended to a more economical point. Conversely, if the
recommended inspection shows,
for instance, a heavy accumulation
of dirt or other foreign matter that
might cause mechanical, electrical
or insulation damage, the inspection and maintenance interval
should be decreased.
What To Inspect
What to inspect and to what extent
is dictated by the nature of the
maintenance function. Routine
inspections require one type of
observation. Inspections following
a known high level fault require
more detailed inspections. When
inspections are complete, be certain that any parts removed during
the inspection process are properly
put back in place.

General Circuit Breaker

A drawout type circuit breaker
should first be withdrawn from its
For more information visit: www.cutler-hammer.eaton.com

compartment onto the compartments extension rails. When the

inspection is complete, the circuit
breaker can be levered to the TEST
position to check any electrical
operations of the circuit breaker.
During movement of the circuit
breaker out of and back into its
compartment, be alert for any signs
indicating improper operation.
During the inspection of fixed type
circuit breakers, bus systems supplying the circuit breakers should
be de-energized for convenience
and safety.
Once the circuit breaker has been
cleaned, visually inspect it for any
signs of damage, missing or loose
parts and unusual wear. On drawout circuit breakers, inspect the
primary disconnect finger clusters
for signs of wear and erosion.
Make appropriate corrections for
anything found out of order.
The trip unit can also be functionally
tested during this general inspection.

Arc Chute
When the circuit breaker experiences a high level fault or during
regularly scheduled maintenance
periods, arc chambers and their
enclosed arc chutes should be
inspected for any kind of damage
or dirt. Be especially alert for signs
of erosion of the V-shaped plates
inside the arc chutes.
Primary Contacts
Since the arc chutes are removed,
this is an ideal time to inspect primary contacts for wear using the
circuit breakers contact wear indicators. Visually inspect each primary
contact structure for signs of wear
and/or damage. This inspection is
conducted with the circuit breaker
closed. Look straight down into the
arc chamber when observing the
closed contacts. If the contacts
show unacceptable wear as indicated by the contact wear indicator discussed earlier in this document, the
contacts should be replaced.

Tables 3.3, 3.4 and 3.5 Magnum DS Factory Installed Current Sensors and Rating Plugs Option for Fixed
or Drawout Circuit Breakers (Character Positions 11 and 12 of Catalog Number)
Depending on the circuit breaker frame type, select current sensors and rating plugs from Tables 3.4, 3.5 or 3.6. One current sensor per phase and one
rating plug are included as standard with all fixed and drawout circuit breakers unless a circuit breaker is non-automatic. Select NN for character positions 11 and 12 if the circuit breaker is non-automatic (without integral trip unit protection). Select the current sensor and rating plug rating by circuit
breaker frame size. For 3-pole circuit breaker ground fault applications on 3-phase, 4-wire circuits, external neutral mounted current sensors must be
ordered separately.

Digitrip 520MC Trip Unit requires PowerNet Software version 3.2 or higher if PowerNet is used
Power Relay Module mounted integral to circuit breaker receives power from an external customer supplied source wired through the
breaker secondary contacts. The external source powers the trip unit digital display (520M, 520MC and 1150), communications functions
(520MC and 1150) and relays
No Power Relay Module provided for 520M trip unit when this catalog code is selected. The Digital display powered from current sensors
and the circuit breaker must carry 20% rated sensor current to power up the trip unit digital display.
Digitrip 1150 has programmable relay trip or contact A for trip unit protective and high load functions.
The maximum available instaneous interrupting rating for the Magnum DS Standard Frame Non-Automatic Switch is 85kA when the
breaker is used with a suitable external overcurrent protective device with instantaneous protection.
