    Cutler-Hammer Type DS LowVoltage Power Circuit Breakershave set the industry standard forover three decades. When reliabil-ity and customer service areparamount, Cutler-Hammer is themarket leader for ANSI/UL applica-tions

    There is a new generation of Cutler-Hammer Power Circuit Breakersthat are smaller with higher per-formance and more versatility.

    Magnum DS

    Magnum DS Low Voltage PowerCircuit Breakers are designed forultimate application flexibility,with the needs of both the powerdistribution equipment user andthe low voltage electrical equip-ment manufacturer in mind.

    For maximum safety, a modern,through-the-door design permitsaccess to the breaker levering sys-tem, trip unit, controls, and indica-tors with the door closed.

    High withstand and interruptingratings provide for maximum selec-tivity and system coordination tomeet the needs of the high avail-able fault currents on todays elec-trical power distribution systems.

    Field installable accessoriesminimize inventory and permit UL-approved field installation of cur-rent sensors, rating plugs, trip unitsand accessories.

    A compact and modular familyof breaker frame sizes makes thedesign of compact, economicaland versatile enclosures a reality.

    2 Overview

    Magnum DS The New Standard in Low Voltage Power Circuit Breakers

    Magnum DS circuit breakers areavailable in a family of threephysical frame sizes.

    The MDN narrow frame is thehighest performing power circuitbreaker of its size and rating class.Continuous current ratings areavailable from 800 to 1600amperes (drawout) and 800 to 2000amperes (fixed mounted).Withstand and interrupting ratingsare available from 42 to 65 kA at600Vac. The MDN compact sizeallows for application in compactenclosures of many types.

    The MDS standard frame is ideal-ly suited for the construction of ver-tically stacked modular ANSI/ULSwitchgear and Switchboards.Continuous current ratings areavailable from 800 to 3200 amperesin the same frame with uniform 5inch pole center spacing.Withstand ratings are available to85 kA and interrupting ratings to100 kA at 600 Vac for improved sys-tem coordination and service conti-nuity.

    The MDS double-wide frame isideal for application as main andtie breakers in high capacity powerdistribution systems. Continuouscurrent ratings are available in 4000and 5000 amperes. A 6000 rating isavailable when the breaker isapplied in a suitably designed andtested fan cooled enclosure.Withstand and interrupting ratingsare available to 100 kA at 600Vacfor maximum system coordinationwith down stream devices.

    The Magnum DS circuit breaker issignificantly smaller than previ-ous generation open type metalframe power circuit breakers. Highstrength, thermoset compositeresin materials used in the breakerframe provide increased strengthfor higher capacity ratings. Thisleads to the design of smaller andmore economic enclosuresusing far less critical floorspace.

    The modern, through-the-doordesign construction results inenclosures of shallower depth,while providing three position dra-wout levering and storage with theenclosure door closed.

    The modular design of theMagnum DS standard and double-wide frames is the key to designsimplification and more compactSwitchgear. Two columns of sin-gle-wide circuit breakers can bestacked over or under double-widebreakers with a common riser bus.

    Magnum DS circuit breakers havehigher levels of performancethan conventional metal framepower circuit breakers.

    Higher interrupting capacityallows Magnum DS to be appliedon power distribution systems withhigher available fault currents.

    Higher short time (withstand)current ratings along with selective(LS) Digitrip RMS trip units resultsin improved selectivity betweenmain, feeder, and branch circuitbreakers.

    The MDN narrow frame circuitbreaker is available in a compactcassette with horizontal primarystabs and terminals, making it idealfor single high compact enclosures.Optional vertical adapter kits areavailable for applications wherebus bar termination in the verticalplane or multiple stacking of break-ers is preferred.

    MDS standard and double-wideframe circuit breakers are avail-able in two types of cassettes; theuniversal and basic cassette. Bothhave vertical primary terminalstabs for interface with the breaker.A uniform 5 inch pole center spac-ing makes these cassettes ideal forapplications that require stacking ofmultiple circuit breakers in a singleenclosure structure.
