Through-the-door design: Thefollowing functions may be performedwithout the need to open the circuitbreaker doorlever the breakerbetween positions, operate manualcharging system and view the spring

charge status flag, close and openbreaker, view and adjust trip unit andread the breaker rating nameplate.

Through-the-Door Design

Cassette design: The breaker cassettesupports the breaker in the cell, as wellas on the movable extension railswhen the breaker is placed into orremoved from the cell. The extensionrails allow the breaker to be drawnout without having to de-energize theentire switchgear lineup.

Accessibility: When the door is open orremoved, each breaker compartmentprovides front access to isolated,vertical wireways, primary discon-nects, cell current transformers andother breaker compartment accessoriesfor ease of field wiring and trouble-shooting field connections.

Breaker Cell

Four-position drawout: Breakers canbe in connected, test, disconnected orremoved position. The breaker can bemoved between the connected, testand disconnected positions while thecompartment door is closed.

Closing spring automatic discharge:Mechanical interlocking automaticallydischarges the closing springs whenthe breaker is removed from itscompartment.

Optional safety shutters: Positive

acting safety shutters that isolate thebreaker connections to the main buswhen the breaker is withdrawn fromthe cell is an option offered for addi-tional safety beyond our standarddesign. They reduce the potentialof accidental contact with live bus.Insulating covers (boots) arefurnished on live main stationarydisconnecting contacts in compart-ments equipped for future breakers.

Breaker inspection: When withdrawnon the rails, breaker is completelyaccessible for visual inspection; tilting isnot necessary. The rails are permanent

parts of every breaker compartment.Interference interlocks: Supplied onbreakers and in compartments wherethe compartments are of the samephysical size. Interference interlocksensure an incorrect breaker cannotbe inserted.

Optional key interlock (switchgearmounted): This mechanism holds thebreaker cell mechanically trip-free toprevent electrical or manual closing.Breaker can be stored in compartment,and completely removed for mainte-nance or for use as a spare withoutdisturbing the interlock. Modification

of the breaker is not required. Anadditional single cylinder breakermounted key interlock is availableas an option.

Optional mechanical interlock:Available between adjacent breakersto ensure the proper sequence ofoperation between two circuit breakersor a circuit breaker and a fuse truck.

Bus Features

Buses and connections: Verticaland cross bus ratings in Magnum DSswitchgear are based on a UL andANSI standard temperature rise of

65 C above a maximum ambient airtemperature of 40 C. As an option,55C temp rise over a maximumambient air temp of 40 C is available.

Bus ampacities: Vertical and cross busratings in Magnum DS are 2000, 3200,4000 and 5000 A. In addition, a 6000,8000 and 10,000 A cross bus rating isavailable. Vertical section bus is sizedper main cross bus maximum ratingor by ANSI C37.20.1 Section 7.4.1.3.Table 11 to a maximum of 5000 A.

Bus bracing: Unique vertical busconfiguration provides an optionalindustry-leading short-circuit with-stand rating of 200,000 A. Standardbracing is 100,000 A. The U shaped

bar is the heart of the Magnum DS

vertical bus. This configurationprovides a much higher mechanicalstrength. To further demonstratethe strength and rigidity of this bussystem, it has been verified throughtesting to withstand 85,000 A short-circuit for a full 60 cycles.

Silver plating: Bolted, silver-platedcopper main buses are standard. Theplating is over the entire length of thebar, not just at the joints. Optionaltin-plated copper buses are available.

Bus joints: All joints are bolted andsecured with Belleville-type springwashers for maximum joint integrity.These washers reduce the potential ofjoint hardware loosening during thechange of joint temperature associatedwith variations of the loads. Optionalmaintenance-free hardware is alsoavailable.

Full neutral: For four-wire applications,the neutral bus is rated 100% of mainbus rating as standard. Neutral ratingsup to a maximum of 10,000 A areavailable as an option. Additionally,four-pole breakers can be used inconjunction with four-wire systems.

Ground: A ground bus is furnished

the full length of the switchgearassembly and is fitted with terminalsfor purchasers connections.

Glass reinforced polyester andUltramidstandoff insulation system:Glass reinforced polyester has beenused on both low and medium voltageswitchgear for decades. By combiningthis industry proven material withUltramid insulation, a total systemproviding exceptional mechanical anddielectric withstand strength, as wellas high resistance to heat, flame andmoisture, is produced. Substantialtesting to demonstrate acceleratedeffects of heating and cooling on the

mechanical and dielectric propertiesof this system prove it to providesuperior performance for decadesof trouble-free operation.

Magnum DS Arc-Resistant Switchgear

ArcGard Magnum DS Switchgear

Arc-resistant low voltage switchgearis a new development in the MagnumDS line that protects operating andmaintenance personnel from danger-ous arcing faults by channeling the arcenergy out the top of the switchgear.Arc faults, caused by human erroror insulation failure, can generatethermal energy as high as 35,000 Fand a blast equivalent to 20.7 lbs ofTNT. While arc-resistant gear does notprevent these arcs from occurring, itdoes safely redirect and contain thesearcs that do occur, regardless of theoriginating location of the arc. ArcGardMagnum DS switchgear has been

tested in all three compartments for afull 0.5 seconds, passing ANSI Type 2and Type 2B standards at 100 kA at508 V and 85 kA at 635 V.

Arc-Resistant SwitchgearAccessibility Types

Arc-resistant switchgear performanceis defined by its accessibility type inaccordance with IEEE test guideC37.20.7 as follows:

Type 1: Switchgear with arc-resistantdesigns or features at the freelyaccessible front of the equipment only.

Type 2: Switchgear with arc-resistantdesigns or features at the freelyaccessible exterior (front, backand sides) of the equipment only.(Type 2 incorporates Type 1.)

Type 2B: Switchgear with Type 2accessibility plus arc-resistant infront of the instrument/controlcompartment with the instrument/control compartment door opened.(Type 2B incorporates Type 2.)

Normal Operating ConditionsArc-resistant features are intendedto provide an additional degree ofprotection to the personnel performingnormal operating duties in close prox-imity to the equipment while

the equipment is operating undernormal conditions.

The normal operating conditions forproper application of arc-resistantswitchgear designs are as follows:

All doors and covers are properlyclosed and latched

Pressure relief devices are free tooperate

The fault energy available to theequipment does not exceed therating of the equipment (short-circuit current and duration)

There are no obstructions around

the equipment that could direct thearc fault products into an areaintended to be protected

The equipment is properlygrounded

The user should also refer todocuments such as NFPA 70E, forsafety training and safe work practicesand methods of evaluating safe workdistances from energized equipmentbased on the potential flash hazard,and use proper PPE when workingon or near energized equipmentwith the door/cover opened or notproperly secured.

Arc-Resistant SwitchgearProduct OfferingArc-resistant switchgear comesstandard with:

Up to 100 kA short circuit at 508 Vacmaximum and 85 kA short circuit at635 Vac maximum

Up to 10 kA horizontal main buscontinuous current

Up to 5 kA vertical buscontinuous current

Magnum DS power circuitbreaker frame ratings between

800 A and 6000 A Up to four high breaker configura-

tion with no additional layoutrestrictions (requires 10-footfloor to ceiling clearance)

Standard Features ANSI Type 2 arc-resistance: Type 2

arc-resistant switchgear regardlessof whether the arc originates thebreaker, bus or cable compartment

Stronger door and latch:The robustdoors are made of heavy 12 gaugemetal and secured with two-pointlatches

Bellows and Two-Point Door Latch

Breaker bellows:Bellows surroundthe breaker door, preventing arcgasses from escaping around thenose of the breaker while ensuringeasy racking of the breaker into thedisconnected position

Rear dynamic flap system:Theventilation openings in the breakermust be open during operation toallow proper equipment ventilation,but sealed off during an arc event.The rear dynamic flap system usesgravity to keep the flaps open

during normal operating conditionsand the arc pressure wave to closethe flaps during an arcing event. Itis a passively designed system sothere are no electrical or automatedparts that could break or fail

Magnum DS PowerCircuit Breakers

Eatons Type MDS power circuitbreakers constitute a complete,modern and rugged line of low voltage

power circuit breakers using EatonsDE-IONprinciple of arc extinction.The breaker family is distinguishedby its similarity of appearanceand operation frame to frame. Allframe sizes are either manually orelectrically operated. Refer to Tab 26for detailed information on MagnumDS low voltage power circuit breakers.

Breaker Features

Four Physical Frame Sizes

Narrow, standard, double narrow anddouble to promote breaker applicationin compact modular enclosures and to

improve enclosure density.

Contacts

Magnum DS has silver tungstenmoving contacts and silver graphitestationary contacts. The contactsprovide a long-wearing, low-resistancejoint. The contacts are protected fromarcing damage even after repeatedinterruptions by the heel-toe action,which causes the integral arcingcontacts to mate before the maincontacts part. The arcing contactsthen part last, striking the arc awayfrom the main contacts.

The main contacts are of the butt typeand are composed of multiple fingersto give many points of contact withoutalignment being critical.

Magnum DS Breaker Contacts(Arc Chutes Removed)

Stored-Energy Mechanism

A cam-type closing mechanismcloses the breaker. It receives itsenergy from a spring that can becharged by a manual handle on thefront of the breaker or by a universalelectric motor.

Release of the stored energyis accomplished by manuallydepressing a button on the frontof the breaker or electrically energizinga releasing solenoid.

Magnum DS Low Voltage Power CircuitBreakers have high withstand ratingsfrom 42 to100 kA to provide for maximumsystem coordination and selectivity.

Magnum MDSL Current Limiting PowerCircuit Breakers have integral currentlimiters to provide interrupting ratingsof 200 kA at 600 Vac.

Magnum MDSX Current Limiting PowerCircuit Breakers have fast openingcontacts to provide interrupting ratingsup to 200 kA at 480 Vac without fuses.

Magnum DS


Arc Chute

There are three basic means ofextinguishing an arc: lengtheningthe arc path; cooling by gas blast orcontraction; deionizing or physicallyremoving the conduction particles

from the arc path.The DE-ION principle is incorporatedin all Magnum DS circuit breakers.This makes possible faster arcextinction for a given contact travel,ensures positive interruption andminimum contact burning.

Levering Mechanism

The worm gear levering mechanismis self-contained on the breakerdrawout element and engagesslots in the breaker compartment.A standard 3/8-inch (10 mm) driveset is used to lever the breakerbetween the connected, test and

disconnected positions.

Mechanical interlocking is arrangedso that levering cannot be accom-plished unless the breaker is in theopened position.

Protection During Levering Operation

When levering the breaker betweenthe connected, test and disconnectedpositions, the operator is protectedfrom contact with live parts by thebreaker door.

True two-step stored energy closing:Refers to the sequence required tocharge and close the breaker.

1. The breaker closing springs arecharged either through themanual-charging handle or bythe optional charging motor.The breaker is mechanically inter-locked to prevent closing of thebreaker until the closing springsare fully charged.

2. With the closing springs fullycharged, the breaker can thenbe closed by pressing the manualclose pushbutton on the breaker,or by the optional spring releasecoil through a remote electricalsignal.

This means that the energy requiredto open the breaker is always restoredfollowing a closing operation.

Stored energy is energy held inwaiting, ready to open or close thebreaker within five cycles or less.The unique cam and spring designprovides necessary energy for a singleclose-open sequence as well as the

energy for multiple charge-closeoperations such as this possiblesequence: charge-close-recharge-open-close-open.

The closing springs are interlockedwith the breaker racking mechanismto ensure the closing springs aredischarged before the breaker canbe removed from the compartment.

Provisions for padlocking: All breakersinclude provision for padlocking opento prevent electrical or manual closing.This padlocking can secure the breakerin the connected, test or disconnectedposition by preventing levering of the

breaker.Ease of inspection and maintenance:Magnum DS breakers are designed formaximum accessibility and the utmostease of inspection and maintenance.

Manually operated breakers:Manually operated breakers areequipped with a manual charginghandle to charge the closing springs.Manual closing and tripping pushbut-tons are used to operate the breaker.Remote closing and tripping can beaccomplished by installing optionalelectric spring release and shunt tripcoils (see Tables 20.1-10and 20.1-11for

available control voltages, currentsand motor-operated spring chargingtimes). The breaker closing springsmust be charged manually, thenremote closing and tripping signalscan be sent to the breaker.

Electrically operated breakers:Electrically operated breakers areequipped with a spring charging motorand electrically operatedspring release and shunt trip coils(see Tables 20.1-10and 20.1-11foravailable control voltages, currentsand motor-operated spring chargingtimes). The breaker manual charginghandle can be used to charge theclosing springs when power is notavailable to the charging motor.

Magnum DS SwitchgearTrip Units

Digitrip RMS trip unit. EatonsDigitrip RMS trip units feature adependent curve that is depicted in

the nameplate by a blue shaded areaof the trip curve. The dependent curveaffords better protection flexibility.Additionally, all of the trip units have,as standard, thermal memory, 50/60 Hzoperation and thermal self-protectionat 90 C.

Digitrip RMS integral microprocessor-based breaker overcurrent tripsystems: Provide maximum reliabilitywith true rms sensing as standard,gives excellent repeatability andrequires minimum maintenance.No external control source isrequired for its protective functions.

Digitrip 1150+

Trip functions: Magnum DS trip unitsprovide the maximum in flexibility andare available in the following configu-rations: LSI, LSIG, LSIA (ground faultalarm only). In each case, either theshort delay or instantaneous (not both)

functions may be defeated. Thisreduces the need for spare breakerinventories and provides maximumusage of interchangeable breakers.

Digitrip RMS 520: Enables the useras many as nine phase and groundcurrent protection settings for maxi-mum flexibility in trip-curve shapingand multi-unit coordination, and addszone selective interlocking.

Digitrip RMS 520M: Adds phase,neutral and ground current meteringwith a four-character LCD displaywindow with 2% current meteringaccuracy and type LSIA alarm when

ground fault settings are exceeded.Digitrip RMS 520MC: Adds communi-cation of trip values and breaker status(open, close and tripped). AddsArcflash Reduction MaintenanceSystem (ARMS).

Digitrip RMS 1150+: Providesprogrammability for more sophisti-cated distribution systems. AddsArcflash Reduction MaintenanceSystem (ARMS).

Zone selective interlocking: TheDigitrip RMS zone selective interlocking(ZSI) capability provides positivesystem coordination without timedelays. ZSI allows the breaker closestto the fault to trip without any preset

time delay. The breaker closest to thefault trips first, while the remainderof the distribution system remainsonline, thus avoiding unnecessaryand costly downtime.

The use of ZSI in Spot NetworkSystems is not recommended byEaton. See the discussion in section 18for the technical reasons why Eatondoes not recommend ZSI in SpotNetwork Systems.

Arcflash ReductionMaintenance System

The Arcflash Reduction MaintenanceSystem Maintenance Mode functionof the Digitrip 520MC and 1150+ can

reduce arc flash incident energy that isgenerated on a fault condition. EatonsArcflash Reduction MaintenanceSystem employs a separate, dedicatedanalog trip circuit that eliminatesmicroprocessor latencies, resultingin clearing times that are faster thanstandard instantaneous tripping. Thisprovides superior arc flash reductionto competing systems that simplylower the standard instantaneouspickup set point.

There are three ways to arm theMaintenance Mode Arc FlashReduction setting. One method is

locally at the trip unit front panel. Forthe 520MC, the 2-position switch in theMaintenance Mode section of the tripunit is used. Turning the switch to theON position will arm the setting. Forthe 1150+, the local front keypad isused to enable the Maintenance Modesetting. The setting is located in theSYSTEM submenu of programmablesettings (PGM SET).

For the second method of arming theMaintenance Mode function, a remoteswitch wired through the breakersecondary contacts can remotelyarm the Maintenance Mode setting. Ahigh-quality gold-plated or palladium

contact is required in this application.A third method to arm the mainte-nance setting is via a communicationdevice. This can be accomplishedthrough a Power XpertGateway.A BIM (Breaker Interface Module),Power Xpert software or PowerNetsystem is another communicationmethod to arm the setting.

For Magnum DS breakers, the ArcflashReduction Maintenance System settinghas five unique settings (2.5, 4.0, 6.0, 8.0,10.0 x In). To adjust this setting, a rotaryswitch on the trip unit face is providedfor the 520MC while the 1150+ trip unit

uses its local keypad. For the SeriesNRX breakers, the Arcflash ReductionMaintenance System setting has aconstant setting of 5000 A.

For all three arming methods, the520MC provides a blue LED to confirmthe Maintenance Mode function is on.In addition, there is also a normallyopen breaker contact that allows theuser to wire in an external stacklight orannunciator for remote indication. Forthe 1150+, the message MaintenanceMode Enabled will be shown on itsLED display. The 1150+ also has analarm relay that can be programmedto track the Maintenance Mode state.

The Maintenance Mode function willprovide fast tripping even when theregular Instantaneous is set to OFF.The Instantaneous LED position isalso used to indicate a trip initiatedby the Maintenance Mode setting.

The 520MC LCD display, if powered,will indicate with four dashes whilethe 1150+ will display the messageMaintenance Mode Trip.

Arcflash Reduction Maintenance System

The Arcflash Reduction MaintenanceSystem can be wired out to a separatelockable switch/light combinationmounted on the switchgear for easeof operation. Additionally, the switchcan be wired out to a remote stationfor operation outside the arc flashboundary of the switchgear, and thealarm can be wired to an optionalbeacon or audible device.

Series NRXGeneral Description015

Series NRX

Series NRX Breakers Have a CompactBut Powerful Size to Provide InterruptingRatings up to 65 kA at 480 Vac

General Description

The Series NRX provides the perfor-mance of a power circuit breaker65 kA interrupting at 480 Vacin thecompact size of a molded case breaker.It offers the protection and features ofa power circuit breaker, along withincreased flexibility at a portion ofthe size.

All frame sizes are either electricallyor mechanically operated. The SeriesNRX is tested to 20,000 mechanicaloperations and 10,000 electricaloperationssignificantly higher thanindustry standards, such as UL andIEC, require or the capabilities of

equivalent products on the market.Thus, your maintenance personnelcan do what needs to be done, insteadof spending valuable time inspectingand maintaining the breakers inthe system.

In switchgear, its important that thebreaker be easily accessible duringscheduled equipment maintenance.The design of the breaker and cassetteenables full use of the breaker handleand cassette rails with a gloved hand,

allowing electricians to remain in theappropriate PPE protective gear.

The breakers ergonomic design alsomaximizes functionality. IndividualSeries NRX breaker door will open ina saloon or barn type of arrange-ment so that personnel can access oneof the side-by-side breakers withouthaving to interact with the other. Thebreakers handle allows the operatorto easily apply leverage across sevencomplete strokes (with an averageof only 21 lbs of force) chargingthe breaker quickly and easily, andmaking it easier to cycle when neededduring commissioning or scheduled

maintenance. Series NRX breakers usea true two-step stored energy mecha-nism similar to Magnum DS breakers.

The reduced weight of the Series NRXmakes it easier to handle during start-up and scheduled inspection. A three-pole, fully populated drawout breakerweighs only 54 lbs/24 kg.

The Series NRX enables twice as manyfeeder breakers in a standard structurefor a reduction in overall assembly sizeof up to 50%.

The small size, 10.00 inches (254.0 mm)wide by 10.70 inches (271.8 mm) deep

by 14.20 inches (360.7 mm) high, ofthe Series NRX allows for much higherdensities of power circuit breakersin a structureup to eight breakersin a 24.00-inch (609.6 mm) widestructureand a 2.50-inch (63.5 mm)customer wireway. This means that twoSeries NRX breakers can be mountedside-by-side in the same space typicallyused for one Magnum DS breaker.

The Series NRX breakers can also bemixed and matched with Magnum DSbreakers, increasing layout flexibilityand providing the ability to stackfeeder breakers around larger mainand tie breakers. See layout guide formore details.

All optional Magnum DS breakerattachments and accessories are alsoavailable for the Series NRX breakers.Series NRX accessories can be quicklyinstalled at the job site, without anyspecial tools. Each breaker comes

standard with an accessory tray; theneeded accessories simply plug andlock into the tray.

The Series NRX uses one CT for thebreaker frame. This eliminates theneed to match CTs and rating plugs tochange the continuous current ratingof the breaker. For example, changingfrom 1200 to 800 A on previous breakerdesigns required changing CT from1200 to 800 A and changing the ratingplug from 1200 to 800 A. The SeriesNRX breaker simplifies this processby only requiring changing the 1200 Arating plug to 800 A. This is accom-plished through the Series NRXs

Rogowski air core CT. The Rogowskicoil does not saturate like a traditionalferrous core CT, allowing the CT to beused across a broad current rangewith greater accuracy. One sensoraccommodates 2001200 A range.

A full range of trip units, ranging frombasic protection (LSI or LSIG) to meter-ing, system diagnostics, protectiverelay functions and communications,complement the breaker offering.Two of the trip unit models, theDigitrip 520M and 1150, include(optional) Eatons Arcflash ReductionMaintenance System, built to reduce

arc flash energy on a downstreamunit during system maintenance. Zoneselective interlocking is also available.

When communication capabilityis required, the Series NRX breakerhas cassette-mounted modules,eliminating the need for readdressingreplacement breakers. These DIN railmounted modules save space andtime during installation and areavailable for field mounting capability.Modules for Modus and EatonsINCOM system are available withfuture releases for PROFIBUS andEthernet compatible with EatonsPower Xpert Architecture protocols.

Monitors and displays parametersfrom Digitrip 1150+ circuit breakertrip unit. Supports as many as 50of these devices up to 10,000 ft

(3048 m) away Communicates the information from

these protective and energy moni-toring devices over a PowerNetnetwork to a computer or PLC

CommunicationsFor remote power monitoring andsoftware, see PowerNet Tab 2.

Low Voltage HighResistance GroundingSee Tab 36for more details.

C-HRG Wall-Mounted Unit(Separately Mounted Resistors Not Shown)

Where continuity of service is a highpriority, high-resistance grounding canadd the safety of a grounded systemwhile minimizing the risk of serviceinterruptions due to grounds. Theconcept is a simple one: provide a pathfor ground current via a resistance thatlimits the current magnitude, andmonitor to determine when anabnormal condition exists.

This provides for maximum continuityof service, because no tripping occursfor the resistance limited ground fault.

HRG can be installed as stand-aloneequipment (as shown in photo) or canbe integrated into Magnum DS lowvoltage switchgear; however, the useof HRG is restricted to systems thatdo not have single-phase or phase toneutral loads.

Notes: Full Load of Section or Breaker comes from the frame or bus ratings of the product.Actual Amperes is a loading profile over all the devices for the operating scenario of interest.Rating Factor is a value that appropriately weights the nominal losses at full load to the actual losses for the actual loading value.The formula is Rating Factor = (Actual Loading/Full Load Rating) x (Actual Loading/Full Load Rating).The Rating Factor is applied (multiplied) by the Full Load Loss Watts to get Net Watts for each item.See Table 20.1-7for Nominal heat loss data for devices and sections.

Magnum DS and Series NRX Low Voltage Power Circuit Breaker Family ANSI Rated for Switchgear Applications

Table 20.1-9. Magnum DS Switchgear Class UL 1066 Low Voltage Power Circuit Breakers

1 Interrupting ratings shown based on breaker equipped with integral Digitrip RMS trip unit. Interruption ratings for non-automatic breakers are equalto the published short-time withstand rating. These interruption ratings are based on the standard duty cycle consisting of an open operation, a15-second interval and a close-open operation, in succession, with delayed tripping in case of short-delay devices. The standard duty cycle forshort-time ratings consists of maintaining the rated current for two periods of 1/2 second each, with a 15-second interval of zero current betweenthe two periods.

2 Magnum MDSL current limiting power circuit breaker with integral current limiters. Current limiter selected determines short-time and fixedinstantaneous trip rating. Maximum voltage rating is 600 Vac.

3 Magnum MDSX current limiting power circuit breaker with fast opening contacts.4 Product to be tested. Contact Eaton for product rating.5 Series NRX uses the same sensors for all trip settings. No changes to sensors required.

Ratings

The narrow-band characteristic curveallows close coordination with DigitripRMS tripping devices. Repeatability iswithin 2%.

The maximum breaker current ratingfor any breaker frame size is deter-mined by the rating of the sensor used.

The breaker current rating for anyframe size can be changed by simplychanging the sensors and associatedrating plug, which are easily removedfrom the breaker drawout element.The wide range of long-delay pickupmakes one set of sensors more flexibleon a wider range of loads. The DigitripRMS itself need not be changed whenthe associated sensors and ratingplugs are changed.

Eatons Digitrip RMS can be suppliedin various combinations of fourindependent, adjustable, overcurrentprotection functions:

Long delay (L)

Instantaneous (I)

Short delay (S)
