MAGNUM DSLOW VOLTAGE POWER CIRCUIT BREAKERSHighest ANSI Interrupting and Short Time (Withstand)Ratings in the Industry

MAGNUM DS LOW VOLTAGE POWER CIRCUIT BREAKERSNew through-the-doordesign provides clearand safe access to thetrip unit and all breakercontrols and indicators.Even breaker levering isaccomplished with thebreaker compartmentdoor closed.Only Two Physical Frame Sizes■Six continuous current frame sizes, 800 through5000 amperes, are covered by two physicalsizes that have the same heights and depths.AmperesDimension – InchesH D* W800-3200 16.40 15.40 16.304000-5000 16.40 15.40 34.20A Selection of Trip Units Provide ExpandedProtection and Information Capabilities■ A new family of proven, industry-leadingCutler-Hammer Digitrip RMS Trip Units.■ Accuracy of 1% of metered values and 2%of energy and power.MAGNUM DIGITRIP TRIP UNITSHighest Interrupting and Short Time (Withstand)Ratings…in the Smallest Physical SizeDesign innovations provide opportunities thatare unique in an ANSI power breaker:■■■■A system design that can withstand largeravailable fault currents, increasing systemreliability.Improved coordination with downstreamdevices, increasing system uptime.Elimination of limiters in most instances,reducing cost and floor space.Smaller switchgear footprint, reducingfloor space.Highest ANSI Ratings Available WithoutCurrent Limiters■■Up to 100 kA at 600 V AC interrupting capacity.Up to 100 kA 1.0 second at 600 V AC shorttime (withstand) capacity.Breaker Cassette■Secondary contacts arelocated at the top providingfor easy access.Primary disconnects aresafely located at the rearof the breaker.Electrical accessories areplug-in mounted in specialcavities, saving installationtime and cost. Uniquewindows in the breakercover enable accessoriesto be quickly viewed byname and rating.Integrally designed breaker cassette fordrawout breakers provides clear indicationof connect, test and disconnect positions.*Drawout breaker with finger clusters.MAGNUM DS WITHOUT CURRENT LIMITERSBreaker Ratings at 240, 480 and 600 VoltsMaximum Breaker Interrupting Short TimeAmperes Designation Rating RatingRigid Frame Housing■■Provides the strength and stability required byan operating mechanism during arc interruption.Thermoset composite resin housingprovides excellent structural properties,dielectric strength, and arc track resistance.Two-Step Stored Energy Mechanism■■Energy is held in waiting to close the breakerin 5 cycles or less. Energy required to openthe breaker is always pre-stored following aclosing operation.After closing, the charging spring can berecharged to provide energy for reclosingafter a fault for high continuity of service.Ease-of-Maintenance■■800 MDS-408 42 kA 42 kAMDS-608 65 kA 65 kAMDS-808 85 kA 85 kAMDS-C08 100 kA 85 kA1600 MDS-616 65 kA 65 kAMDS-816 85 kA 85 kAMDS-C16 100 kA 85 kA2000 MDS-620 65 kA 65 kAMDS-820 85 kA 85 kAMDS-C20 100 kA 85 kA3200 MDS-632 65 kA 65 kAMDS-832 85 kA 85 kAMDS-C32 100 kA 85 kA4000 MDS-840 85 kA➀ 85 kAMDS-C40 100 kA➀ 100 kA5000 MDS-850 85 kA➀ 85 kAMDS-C50 100 kA➀ 100 kA➀ Interrupting rating is 130 kA at 240 volts.Visual contact wear indicator shows whencontact replacement is necessary.Stored energy mechanism, control devices,accessories, and secondary contacts areeasily and safely accessible (in the withdrawnand disconnect positions) by removing thefront cover.Functions 220 520 520M 1150LSIG Protection Yes➀ Yes Yes YesDisable (I) No Yes Yes YesGF Protection No Yes Yes YesGF Alarm No No Yes YesDisplay No No Yes➁ Yes➂Programmable No No No YesMetering No No Yes➃ YesPower andEnergy ValuesNo No No YesPower Quality No No No YesCommunication No No No Yes➀ Long and Instantaneous only.➁ One-line, (four characters per line) LCD display.➂ Three-line, (eight characters per line) LED display.➃ Phase, neutral, ground, and high load current only.100 Percent Rated…Meets or ExceedsANSI and UL Standards■ Magnum DS Breakers are 100 percentrated, UL listed, and are built and tested inan ISO 9000 certified facility to applicablestandards including ANSI C37.13, C37.16,C37.17, C37.50, NEMA SG3, and UL 1066.■ Suitable for use in UL 1558 LV Switchgear.■ Suitable for use in UL 891 LV Switchboards.■ Suitable for use in UL CSA 22.2.31LV Assemblies.Global ApplicationsFor information and specifications on MagnumCircuit Breakers designed to meet global standards,please contact your local Cutler-Hammerrepresentative.More InformationAdditional literature about this innovative nextgeneration product is available from authorizedCutler-Hammer distributors or sales engineers.For more information on Cutler-Hammerproducts and services, call 1-800-525-2000or 1-732-417-5660, or visit our website atwww.cutlerhammer.eaton.comCopyright Cutler-Hammer Inc., 1998.All Rights ReservedPA22F01SEPittsburgh, Pennsylvania Pittsburgh, PennsylvaniaPublication No. PA.22F.01.S.EMay, 1998Printed in U.S.A. / CMS 2271
