Other Safety Features

AMPGARD starters include manyadditional features designed toprotect operating personnel. Thesefeatures include:

■

Provision for a padlock onthe isolating switch handle inOFF position

■

Shutter barrier between lineterminals and isolation switchstabs is mechanically driven

■

Distinctive marking on back ofswitch assembly appears whenshutter barrier is in position andstarter is completely isolated fromthe line

■

Grounding clips provide a positivegrounding of the starter and mainfuses when the isolating switchis opened

■

High and low voltage circuits are

compartmentalized and isolatedfrom each other

■

The drawout isolation switch iseasily removed by loosening twobolts in the back of the switch.The shutter remains in placewhen the switch is withdrawn

A remote operator for the starterisolation switch is an available option.The AMPGARD Remote Operator (ARO)enables users to open or close theswitch through the use of a pushbuttonstation operated up to 30 feet awayfrom the starter. Users can mount theARO on the front of the starter, plug it

into any available 120 Vac source, theneasily operate the isolation switch fromoutside the starter arc flash boundary.

Eaton’s Type JMT-4/8 and JMT-15 areeach a drawout, lightweight, three-pole,manually operated isolating switchmounted in the top of the starterenclosure. They may be easilyremoved by loosening two bolts in therear of the switch. The JMT-4 is rated400A continuous while the JMT-8 israted 800A continuous. The JMT-15is rated 250A continuous at 15 kV. Allisolation switches have a mechanicallife rating of 10,000 operations.

The component-to-component circuitryconcept includes the mountings forthe current limiting fuses as part of theisolating switch.

Features

A positive mechanical interlockbetween the isolating switch handlemechanism and contactor preventsthe isolating switch from beingopened when the contactor is closed

or from being closed if the contactoris closed.

An operating lever in the isolatingswitch handle mechanism is designedto shear off if the operator usestoo much force in trying to open thenon-loadbreak isolating switch whenthe contactor is closed. This featureensures that the operator cannot openthe switch with the main contactorclosed, even if excessive force isused on the operating handle.

To operate the isolating switch, theoperating handle is moved througha 180º vertical arc from the ON to the

OFF position. In the ON position, anoperator on the back of the handlehousing extends through a bracket onthe rear of the starter high voltagedoor, preventing the door from beingopened with the switch closed. Whenthe high voltage door is open, a doorinterlock prevents the handle frombeing inadvertently returned to theON position.

When the operating handle is movedfrom ON to OFF, copper stabs arewithdrawn from incoming line fingers.As the stabs withdraw, they arevisible above the top of the fuses

when viewed from the front, andsimultaneously grounded. As thefingers are withdrawn, a spring-drivenisolating shutter moves across theback barrier to prevent front accessto the line connections. As theshutter slides into position, distinctivemarkings appear on the back barrier,making it easier to check the positionof the shutter.

400A, 7.2 kV VacuumContactor, Type SL

400A Bolt-in Contactor 7200 Volt Maximum

General Description

Eaton’s Type SL Vacuum Contactorswere designed and engineeredspecifically for use in AMPGARDstarters. 7.2 kV SL 400A VacuumContactors are self-supporting,compact, drawout, three-pole, DCmagnet closed contactors. To permitapplication matching of the starter tothe motor rating, the SL Contactor isavailable in 400A standard and highinterrupting ratings.

SL Contactors are available in thestandard bolt-in configuration andoptional stab-in design. Either bolt-inor stab-in designs can be supplied in atwo-high configuration, with a startermaximum of 400 full load amperes. Thetotal NEMA 1 structure rating cannotexceed 720A for a combination oftwo starters. Refer to Table 10.1-4 onPage 10.1-17 for other ratings.

Design

Eaton Vacuum Contactors are highlyversatile, low-chop contactors that havebeen designed to meet all applicableNEMA standards and are UL® recog-nized components. The contactors

accommodate mechanical interlocksthat function with the starter isolationswitch and with other contactors.These interlocks provide unmatchedsafety and service protection.

The contactors consist of a moldedframe with moving armature, magnetand vacuum interrupters. The contac-tor is easily positioned into the starterand long-life vacuum interruptersprovide many operations with aminimal maintenance program. TheSL operating coils are energized by acontrol board that provides a pulse-width-modulated DC output. Controlvoltages and contactor dropout timesare programmed using a DIP switchlocated on the control board. Thecontrol board is mounted in aprotected cavity in the moldedcontactor frame to prevent inadvertentaccess to the voltage and dropoutDIP switch. Four auxiliary contacts(2NO, 2NC) are supplied with eachcontactor and are wired to terminalblocks on the starter control panel.

The vacuum interrupters employspecial main contact materials thatexhibit a low chop current plus otherspecially engineered characteristicsthat minimize switching surges. Surge

protection is therefore not requireddue to the use of the vacuum contac-tor. Surge protection may be requiredfor other reasons such as the highprobability of lightning strike, etc.

Maintenance

Reduced maintenance is one of theoutstanding features of Eaton’sVacuum Contactor line. The specialcontact material in the vacuuminterrupters provides long life even

under severe operating conditions.The main coils operate with a verylow temperature rise to maximizeinsulation life. Steel bearings onthe main shaft provide long, trouble-free operation.

A simple go/no-go gauge is used forchecking contact wear. Wear can bechecked without removing the contactorfrom the starter. The vacuum contactoris much lighter than previous generationairbreak or vacuum contactors, whichallows for easier insertion and removalfrom the starter structure.

available in a one-high configurationand is rated at 250A enclosed. The250A contactor is available with astab-in type connection only. The 250Acontactor is mounted on wheels andhas similar features to the 800A 7.2 kVcontactor. While the contactor israted at 250A enclosed, the maximumstarter current is 200 full load amperesdue to the maximum availablefuse size.

250A Stab-in Contactor 15 kV Maximum

Current Limiting Fuses

7.2 kV AMPGARD starters use Eaton’sType CLS power fuses with specialtime/current characteristics for motorservice. Type CLE or Type HLE powerfuses are applied with the 15 kV starteror when the 7.2 kV starter is used tofeed a transformer. The fuse is coordi-nated with the contactor and overloadrelay characteristics to provide maxi-mum motor/transformer utilizationand protection. The standard mountingmethod for power fuses is bolted withan option for fuse clips in the 400Astarter. 800A 7.2 kV and 250A 15 kVfuses are supplied as bolted only.

Interruption is accomplished withoutexpulsion of gases, noise or movingparts. Type CLS/CLE/HLE fuses aremounted in a vertical position to ensuremaximum rating reliability, properoperation and to eliminate the possibil-ity of dust and dirt collecting, resultingin a deterioration of dielectric proper-ties. When a fault has been cleared, aplastic indicator in the top of the fuse,normally depressed, pops up to givevisible blown fuse indication. Thisindicator also operates the optionalblown fuse mechanism (availablewith bolted 7.2 kV fuses only) on theisolation switch that gives a contactclosure to allow use in the startercontrol circuit.

The control circuit primary fuses arealso current limiting.

Blown fuses may be removed andreplaced without removing or drawingout the contactor.

Reduced Voltage Starters

General DescriptionEaton offers traditional electrome-chanical reduced voltage starters inaddition to reduced voltage solid-statestarters. Unless otherwise specified,reactors and autotransformers areNEMA medium duty rated. They aredesigned for three 30-second startsper hour. Heavy-duty reactors andtransformers can be supplied whenspecified. Locked rotor current mustbe specified when ordering reducedvoltage starters to ensure that thereactors or autotransformers areproperly sized.

Reduced Voltage Reactor Starter

Reactor Starter

Table 10.1-1. Type 502 Reactor StartingCharacteristics

Factory set on 65% tap.

Advantages

■ Reduces starting currents

■ Least costly reduced voltagestarting method

Disadvantages

■ Large footprint: 1-1/2 structuresat 400A

■ “Bump” on transition to full voltage

■ Not as efficient as autotransformer

■ Due to reduced torque duringstarting, motor must typically beunloaded during the start sequence

Sequence of Operation

■ Main contactor (M) closes

■ Current flows through reactorreducing voltage to motor (basedon tap setting)

■ When motor current reaches~125%, the run contactor (R) closesproviding full voltage to the motor

Reduced VoltageAutotransformer Starter

Auto Transformer Starter

Table 10.1-2. Type 602 Auto-transformerStarting Characteristics


Advantages

■ Produces the most torque perincoming line ampere of anyreduced voltage starting method

■ Less costly than RVSS

Disadvantages

■

Large footprint: 1-1/2 structuresat 400A

■ More costly than reactor

■ “Bump” on transition to full voltage

■ Due to reduced torque duringstarting, motor must typically beunloaded during the start sequence

Note: Care should be taken when selectingthe motor for reduced voltage starting toensure that there is sufficient torque toaccelerate the load at reduced voltage.Motors that do not fully accelerate atreduced voltage will generate high voltagesat transition that can damage the autotrans-former and void the factory warranty.

Sequence of Operation■ Shorting contactor (S) closes

■ Main contactor (M) closes

■ Current flows through autotrans-former reducing voltage to motor(based on tap setting)

■ When motor current reaches ~125%,the shorting contactor (S) opens andthe run contactor (R) closes provid-ing full voltage to the motor

Note: Because the motor is neverdisconnected from the supply voltage,the starting is closed transition.

Solid-State Reduced VoltageAMPGARD MV4S

Eaton offers reduced voltage solid-state soft starters in 400A and 720Aconfigurations. Horsepower ratings

are available through 5000 hp. The400A AMPGARD soft starter requiresone full height structure with a fullvoltage starter in the upper compart-ment bus connected to a soft start truckassembly in the lower compartment.The 720A soft starter requires twofull height structures (total 72 inches(1829 mm) wide). The soft startcomponents are fixed mounted in the720A starter. Both soft starters includeinternal fault protection and built-inbasic motor protection. The standardassembly includes an EMR-3000 motorrelay for advanced motor protection.

Why is Solid-State ReducedVoltage “Soft” Starting Desirable?

■ Eliminate shock to your mechanicalcomponents

■ Avoid coupling and shaft damage

■ Prevent rotor and winding failure

■ Stop drive belt squeal and breakage

■ Prevent water hammer in pipes

■ Soft stop the pump motors

■ Reduce pressure so valves close gently

■ Avoid the surge wave

■ Reduce peak starting currents

■ Reduce voltage drop on motor start

Ratings

■ 2300–4160 Vac grounded systems

■ 60 kV BIL impulse rating

■ Horsepower: to 5000 hp

Refer to Table 10.1-19 on .1-32 for more detailed ratings information.

The AMPGARD solid-state soft starteris recommended for application onlyon power systems that are solidlygrounded or resistance grounded.Ungrounded systems are notrecommended.

Industry Standards

The AMPGARD solid-state starter isdesigned and built to meet all applicableindustry standards. The 400A starter isavailable as a UL listed assembly.

■ NEMA ICS3

■ UL 347

■ CSA

■ EEMAC E14-1

■ Manufactured in an ISO® 9001and ISO 14001 certified facility

Starting CharacteristicsThe soft start controller providesa number of selectable startingcharacteristics as standard:

Kick Start

Provides an initial boost of current toovercome motor and system inertia.

Ramp Start

Operator sets the initial startingvoltage and ramp time. Factorysetting for starting voltage is 20%.Range is 0 to 100%. Factory settingfor starting time is 10 seconds. Rangeis 0 to 120 seconds.

Current Limit

Limits the maximum starting current.Used in long start time applicationsand motor protection applications.Factory setting is 350% of motor FLA.

Range is 200 to 600%.Solid-State Soft Stop

Provides a slow decrease in outputvoltage. Extends the stopping time ofthe motor. Typically used with pumps.

MV4S Keypad and Display

Application with CapacitorsCapacitors of any kind may not beconnected to the load of the solid-statestarter. When power factor correctioncapacitors are required, the capacitorsare connected ahead of the RVSS truckand are switched with a separatecapacitor contactor. If multiple starterswith capacitors are supplied in thesame lineup, all capacitors areswitched off while the solid-statestarter ramps. At the completion ofthe ramp cycle, the capacitors forall energized starters are sequencedback on. Long cable runs may createenough capacitance to be of concern.Capacitance connected to the startermotor connections must not exceed0.3 ufd.

400A MV4S Roll-out Truck

Design

Soft start components and bypasscontactor are mounted in a easy-

to-remove roll-out truck assembly.Maintenance can be performed withthe truck on a bench away from thestarter cubicle.

720A MV4S with Doors Open

How It Works

1. At the time of start, the bypasscontactor is open and all currentpasses through the SCRs thatramp the voltage per the pre-programmed starter settings.

2. After start is complete, the runcontactor closes, taking the SCRsout of the circuit.

3. The SCRs are on for only a shorttime therefore no MCC venting orcooling is required.

4. When a stop command isreceived, the SCRs can beprogrammed to ramp down,providing a soft stop.

Main Breaker Ratings

Table 10.1-10. Available VCP-W Vacuum Circuit Breaker Types Rated on Symmetrical Current Rating Basis, Per ANSI Standards

For reclosing service, there is No Derating necessary for Eaton’s type VCP-W family of circuit breakers. R = 100%. Type VCP-W breaker can performthe O-C-O per ANSI C37.09; O-0.3s-CO-15s-CO per IEC 56; and some VCP-Ws have performed O-0.3s-CO-15s-CO-15s-CO-15s-CO; all with no derating.Contact Eaton for special reclosing requirements.

For three-phase and line-to-line faults, the symmetrical interrupting capability at an operating voltage, Vo = (Rated Short-Circuit Current)But not to exceed KI.Single line-to-ground fault capability at an operating voltage, Vo = 1.15 (Rated Short-Circuit Current)But not to exceed KI.The above apply on predominately inductive or resistive three-phase circuits with normal-frequency line-to-line recovery voltage equal to theoperating voltage.

4000A continuous rating is available for 5/15 kV. Contact Eaton for details. 3-cycle rating available. Tripping may be delayed beyond the rated permissible tripping delay at lower values of current in accordance with the following formula:

T (seconds) =Y

The aggregate tripping delay on all operations within any 30-minute period must not exceed the time obtained from the above formula. Included for reference only. Asymmetrical interrupting capability = “S” times symmetrical interrupting capability, both at specified operating voltage. Non-standard breakers with high momentary rating available for special applications.

Note: Contact Eaton for capacitor switching, low inductive switching, and cable charging ratings.

Contactor-Fuse CoordinationThe AMGARD starter providesensured coordination between itsfuses, contactor, current transformers,protective relays, and the motor itis controlling.

One of the most critical coordinationissues is between the contactor andthe starter fuses. The fuses mustinterrupt faults greater than theinterrupting rating of the contactor.The AMPGARD 400A high interruptingcontactor (SL400A-HI) has an 8-cycledropout time factory setting asstandard and will interrupt at 8500A.The maximum size fuse used with anSL400A-HI contactor is a 450-24R. Bycomparing the fuse curve with thecontactor rating, it can be observedthat for faults greater than 8500A, thefuse will open before the contactor.

With faults less than 8500A, thecontactor may clear the fault beforethe fuse blows, depending on thesettings of the protective relays. Referto Figure 10.1-4 for an illustration ofAMPGARD coordination.

Other vacuum contactors availabletoday may have lower interruptingratings than the AMPGARD Type SLvacuum contactors. Dropout timesalso vary, and may be as short as twocycles on other starter designs. Lowerinterrupting ratings and shorter drop-out times can result in fault currentlevels where the contactor may berequired to interrupt a fault greater

than its rating. This can resultin equipment failure. Refer toFigure 10.1-5 for an illustration ofan improperly coordinated starter.

AMPGARD starters also ensurecoordination between other startercomponents. The current transformersand protective relays are selected towork properly with each other, andto protect the motor. Protective relayslike Eaton’s EMR-3000 provide optimalmotor protection, while also rapidlyopening the contactor during faultconditions. This rapid opening signalcannot open the contactor in less thanits set dropout time, but it will takethe motor off-line in the shortestpossible time. This will help minimize

mechanical damage to the motor andmay prevent the starter fuses fromblowing by allowing the contactor toclear the fault (only if the fault is lessthan the contactor interrupting rating).

AMPGARD starters use 400A standard

interrupting contactors (SL400-SI)when the contactor is not requiredto coordinate with the starter mainfuse. An example of this applicationis the run contactor of a reducedvoltage starter.

Protection ConsiderationsCoordinated with the motor’scharacteristics, the protective devicesin the AMPGARD starter providemotor protection from overload tofull system capacity faults.

AMPGARD starters are supplied withan adjustable thermal overload relayas standard.

Multi-function solid-state motorprotection relays are a commonoption on AMPGARD starters. TheEMR-3000 is typically provided whena multi-function relay is specified.The EMR-3000 provides many types ofprotection including overload, lockedrotor, ground fault and phase loss/ phase unbalance. The EMR-3000 alsoprovides start control logic to protectthe motor against excessive starting.The relay may be applied to either

across-the-line or reduced voltagestarters. On reduced voltage starters,the EMR-3000 can control thetransition from reduced to full voltage,offering the greatest protection for themotor and starter. An optional RTDmodule can be supplied for motorswith built-in RTDs. The EMR-4000 canbe supplied when voltage monitoringand protection are required.

Eaton’s MD-3000 can be supplied whenmotor differential protection is required.

EMR-3000 Motor Protective Relay

InsulGard™ relays are an availableoption on AMPGARD starters. TheInsulGard provides early warning ofincreasing partial discharge levels in

the starting equipment, cables andmotor. This early warning will help theuser to better schedule maintenanceand avoid unplanned downtime.

AMPGARD SC 9000Adjustable Frequency Drive

AMPGARD SC 9000

General DescriptionEaton’s AMPGARD SC 9000 mediumvoltage adjustable frequency drive(AFD) family provides precise controland protection of medium voltagemotors and equipment rated 2400V,3300V and 4160V nominal.

Application DescriptionAMPGARD SC 9000 AFD has acomplete offering:

■ Precise control of medium voltagemotors up to 6000 hp

■ A smaller footprint, 24-pulse frontend, and integrated assembly directcoupled through a common powerbus to the entire AMPGARD productfamily as Integrated Control-Gear

■ Fully integrated package withisolation switch, main contactor,multi-pulse isolation transformer,rectifier and inverter

Features, Benefits and FunctionsPersonnel safety: Positive mechanicalisolating switch with visible discon-nect completely grounds and isolatesthe AFD from the line power with amechanically driven isolating shutter,

leaving no exposed high voltage.Medium voltage door is mechanicallykey locked closed with the isolationswitch; low voltage section has aseparate door and is segregatedfrom the medium voltage section.

Ease of installation: Current limitingfuses, contactor assembly, inverterassembly, and isolating switchassembly are easily removed from theenclosure; line and load terminals arecompletely accessible from the front.

Ease of maintenance: All componentsare front accessible, facilitating routineinspection and/or parts replacement.

The low Mean Time To Repair (MTTR)means a time and cost savings.

Smallest industry footprint: TheSC 9000’s specialized design and highdensity packaging makes it the small-est footprint per hp in the industry as afully integrated drive. This size benefitensures installations in space limitedelectrical rooms, eliminates the needfor additional cable and conduit instal-lations, and in some cases, eliminatesthe need for additional feedersrequired by our competitors.

Clean and quiet: The SC 9000’s inte-grated 24-pulse converter coupledto a 3-level inverter topology resultsin minimum component usage andensures compliance with IEEE 519no matter what the power source is.Heat pipe technology improves coolingefficiency and allows the SC 9000 torun at a 75 dB noise level or less,making it the quietest drive in theindustry. Output filters are requiredfor non-inverter duty motors withcable lengths greater than 100 feetand for inverter duty motors withcable lengths greater than 300 feet.See Table 10.2-2 on Page 10.2-22 for detailed output filter applicationrecommendations. Noise pollution isminimized with the quiet operation.

Easy AMPGARD integration: Availableas a fully integrated drive, the SC 9000can be supplied as a stand-alone drive

or directly connected to other AMPGARD products in a configuration known asIntegrated Control-Gear. This integratedsolution aligns the SC 9000 with a hostof other motor control products, suchas motor starters, load break switchesand main breakers all connected via acommon bus.

Protection through technology: Theencapsulated roll-out inverter employsa patented insulation system, whichreduces the potential of environmentalcontamination. This modular inverterdesign coupled with a spare inverteroption reduces MTTR and results in

maximum uptime.

Adjustable Frequency Drives Synchronous Transfer Systems


Synchronous Transfer Control with AMPGARD SC 9000

Synchronous Transfer Control System

General DescriptionThe sequence of operation outlined isof an Adjustable Frequency Drive/Pro-

grammable Logic Controller (AFD/PLC)synchronous transfer control system.Included in this system is an AFD persystem, a PLC per system, a bypasscontactor and a motor select contactorper motor. The AFD output contactorfeeding the AFD bus is an option andis illustrated for this example.

Application Description

The basic principle is to adjust the AFDoutput voltage, frequency and phaseto match the utility. By matching theseparameters, the system can transfer themotor to the utility in a “bump-less”manner. The AFD and PLC system is

programmed to follow these generalcommands.

■ Start/Stop

■ Sync Up/Sync Down

Once the system bus is energized, theAFD and Feeder Bus are energized.See Figure 10.2-7.

Figure 10.2-7. AFD and Feeder Bus Energized

The Start command will start thesynchronous transfer process. Firstthe PLC will close the appropriatemotor select contactor and then startthe AFD. The AFD will operate at apreset speed or a reference speed.See Figure 10.2-8.

Figure 10.2-8. Synchronous Transfer Process

When the motor is required to transferto the utility line, the PLC will sendthe Sync Up command to the AFD. TheAFD will adjust the output to matchthe line voltage, frequency and phaseangle. Once synchronization is locked,the bypass and motor select contactorare closed and opened such thatparalleling is minimized. The output

reactor dampens transient currents.See Figure 10.2-9.

Figure 10.2-9. Voltage, Frequency andPhase Angle Synchronization

The AFD is shut down and waits foranother Start command for the nextmotor. The first motor is running onbypass. See Figure 10.2-10.

Figure 10.2-10. AFD Shut Down and Waiting

If the PLC receives a command to syncdown, the PLC will start the AFD andclose the motor select contactor; how-ever, the AFD output contactor doesnot close initially. See Figure 10.2-11.

Figure 10.2-11. PLC Receives Command toSync Down

The AFD output will adjust to matchthe utility voltage, frequency andphase. Once these parameters arelocked in, the AFD output contactorwill close and the bypass contactor

will open such that paralleling is mini-mized. The output reactor will dampentransient currents. See Figure 10.2-12.

Figure 10.2-12. AFD Adjusts to Match theUtility Voltage, Frequency and Phase

The AFD will operate at a set speedpoint or follow a reference speed.See Figure 10.2-13.

Figure 10.2-13. AFD Operating Speed

These sequences can be commandedfor any of the motors (1–5) illustrated

and are not limited to just five motorsin a system; however, only one motorat a time can be on the AFD. Eachsystem can be configured to start anynumber of motors, keeping in mindequipment size and layout.

Adjustable Frequency Drives Component Details


Modular Roll-in/Roll-outStab-in Three-Phase Inverter

Plug-n-Play 2500 hp Three-Phase Inverter

General DescriptionThe roll-out three-phase invertermodule employs a patented insulationand buswork system to obtain thehighest power density rating in themarket. Heat pipe technology is usedto cool the active power componentsin the inverter.

Figure 10.2-19. Heat Pipe ThermalManagement System

This method of heat removal fromthe inverter is up to 10 times moreefficient than traditional air-coolingmethods, resulting in less requiredairflow for quieter and more efficientoperation. The thermal managementsystem has been subjected to temper-atures of –50ºC to model cold weathertransport without the rupture of anyheat pipes. It is also important to notethat thermal management performancewas unaffected by the extremecold storage.

Figure 10.2-20. Heat Pipe Construction

This cooling methodology and theencapsulation of the medium voltagecomponents result in a harsh-environ-

ment inverter that protects the activepower devices and circuit boards fromthe environment and airborne contam-inants eliminating potential causes offailures. The encapsulation systemalso protects other components fromflying debris and collateral damage inthe event of a device failure.

In the event of a failure, the modularroll-in/roll-out design of the inverterwill minimize downtime. In traditionalmedium voltage drives, only the devicethat fails is replaced. This can result infuture downtime due to latent failuresof other devices that were damaged inthe original incident. The SC 9000 usesan inverter replacement system thatminimizes mean-time-to-repair (MTTR)and is designed exclusively for thepurposes of inverter module exchange.The system removes the existinginverter safely and effectively and thenallows for the insertion of a replace-ment inverter that is on-site or shippedfrom the factory where spare invertersare stocked.

Type SL Vacuum ContactorStab-in with Wheels, Fuses,and Line and Load Fingers

400A Stab-In Contactorand Fuse Assembly

General Description

400A Vacuum ContactorsA stab-in version of the SL Contactoris standard. The stab-in contactor ismounted on wheels and rolls into theAMPGARD SC 9000 AFD structure.Contactor line and load fingers engagecell-mounted stabs as the contactoris inserted into the SC 9000 AFDincoming cell. The contactor is heldin position by a bolt and bracket com-bination. It can be easily withdrawn

from the SC 9000 AFD incoming cellby removing the bolt holding thecontactor against the bracket anddisconnecting the isolation switchinterlock. The contactor can beremoved from the SC 9000 AFDafter disconnecting the mediumvoltage cables going to the controltransformer.

800A Vacuum ContactorsThe 800A SL Contactor is available inthe SC 9000 Frame D AFD andis rated at 720A enclosed.

The 800A contactor is also stab-in. The

800A contactor is mounted on wheelsand has similar features to the stab-in400A contactor.

Stab-In Contactor Mechanical Interlock and Fingers

Current Limiting Fuses

AMPGARD SC 9000 AFDs use Eaton’sType HLE power fuses with specialtime/current characteristics. The fuseis coordinated with the contactor toprovide maximum motor/transformerutilization and protection. The standardmounting method for power fuses isbolted onto the contactor assembly.

Interruption is accomplished withoutexpulsion of gases, noise or moving

parts. Type HLE fuses are mounted ina horizontal position. When a fault hasbeen cleared, a plastic indicator in thefront of the fuse, normally depressed,pops up to give visible blown fuseindication.

The control circuit primary fuses arealso current limiting.

Blown Fuse Indicating Device

See Page 10.1-4 for detailed informa-tion on current limiting fuses.

See Page 10.1-21 for detailed informa-tion on contactor-fuse coordination.

Isolated Low Voltage ControlThe low voltage door has four cutoutsas standard.

AMPGARD SC 9000 AFD Low VoltageDoor Closed

The Device Panel and optional EatonMP Series Motor Protection Relays fitin the same size low voltage door cut-out. The standard SC 9000 keypad canbe removed for plug-in of a laptop viaa serial connection. A standard view-ing window allows visual verificationof the AMPGARD SC 9000 AFD status.The low voltage control panel isbehind the low voltage door and iscompletely isolated from the mediumvoltage compartment. The mediumvoltage door is locked closed andinterlocked with the isolation switch.

Pre-Charge Circuit

Patented SC 9000 Pre-Charge Circuit

Unlike other pre-charge methods, theinnovative pre-charge circuit in theAMPGARD SC 9000 protects the trans-former, rectifier and DC bus components from high in-rush currents. The designuses the control power circuit for DClink capacitor charging. This featureeliminates the risk of componentor transformer failure during thepre-charge cycle and lengthens thelife of the affected components.

Standards and Certifications

UL and CSA Certification

AMPGARD SC 9000 AFDs are

designed, assembled and tested tomeet all applicable standards: NEMAICS6, NEMA ICS7, IEEE 519, IEEE 1100,UL 347 and CSA C22.2. The majorcomponents (contactor, isolatingswitch, fuses, transformer and inverteractive devices) are UL recognized.

UL or CSA labeling of a specific AFDrequires review to ensure that allrequested modifications and auxiliarydevices meet the appropriate standards.Refer to factory when specified.

Seismic Certification

SC 9000 AFDs are seismically testedper the requirements of the 2009

International Building Code (IBC).SC 9000 AFDs require the use ofspecial keyed door latches on themedium voltage doors to ensurethat the doors do not open duringa seismic event.
