Features Compactness with increased operational capacity
The smallest depth in the world with a 1 second Icw at 65 kA
The innovative design of theTemPower 2 double break contactssystem has eliminated any need foran intermediate flexible conductorin the moving contacts assembly.The result is a more compact maincontact design allowing theTemPower 2 ACB to have the worldssmallest depth for a 65 kA, 1 secondIcw ACB. Switchboard designbenefits in two ways especially, amore space saving ACB, plus alower temperature rise as result offewer moving parts associated withthe double break contacts assembly.
The TemPower 2 ACB has more than20 design patents registeredcovering it’s unique main contactsdesign.
The height and depth dimensions are identical in all sizes up to 3200 A, with only the width varyingaccording to the amp rating. There are two common width or frame sizes from 800-2000 A and from2500-3200 A. The panel cut out size is the same for all sizes of the TemPower 2 ACB, thus simplifyingfitting a variety of breaker sizes into a switchboard. The 4000A TemPower 2 ACB has an increasedwidth & depth, while the height is common with other sizes.
Maximum power from minimum volume was central to the design specification. With a depth of 345 mm, the TemPower 2 is one of the smallest ACBs in the world in terms of overall dimensions andone of the smallest when it comes to depth. TemPower 2 ACBs are available with draw-out carriages,with either front or rear terminal connections. A front connected ACB is especially suitable where aswitchboard has less depth available.

Increased accessibility from the front
No extra arc space required,allowing vertical stacking
Main contactreplacement
For easy wiring access,control voltage, auxiliaryand position switchterminals are all mountedat the front on the ACBbody for easy access. Dueto a general increase in thelevel of line harmonics inmodern power distributionsystems, the neutral phaseis fully rated as standard.
No extra arc space required
The TemPower 2 ACB dissipatesall arc energy within its unique“DoubleBreak” arc chamber.The internal energy dissipationwithin the ACB allows theclearance distance of the ACBto nearby earthed metal to bezero. “Temperature rise”constraints aside, TemPower 2ACBs can be stacked with noarc space clearance being
required. This will assist in minimising switchboard height,and generally saving costs.

Features High performance and reliability
11
Very fast interruption bythe “DoubleBreak” system
The unique“DoubleBreak” main contactssystem ensures very fast interruption of shortcircuit currents with a maximum clearing timeof 30 msec. The double contacts also sharethe arc energy, which substantially reducesmain contact wear. “DoubleBreak” maincontacts allow reverse power connection.
Simplified and strongermain circuit contactassembly
There are no clamp screws or flexible leadsin the main circuit contact units. Thissubstantially enhances the durability of themain circuit contact units and improves theACB’s reliability during its ON-OFFoperations.
AGR2 overcurrent relay closing/tripping circuitry - nomechanical contacts
When advanced TemPower 2 AGR21 or 22 OCRs are used, the internal closing/trippingoperation circuits employ electronic semiconductors for all switching. This ensures bothlonger life and increased reliability for the OCRs internal circuits.
Fully rated Neutral (4th) poleDevices such as UPS power backup systems and variable speed motor controllers, whichutilise inverters, generate a significant amount of line harmonics. Because these types ofdevices have become so common in recent years, the amount of harmonics generated inthe average distribution network has increased significantly. One result of this is higherneutral currents. To meet this requirement the new TemPower 2 ACB has a 100 % fully ratedneutral pole is standard.

New Selectivity capabilities
Terasaki are so concerned aboutselectivity that all AGR overcurrentrelays have ‘LSI’ characteristics asstandard.
This provides an adjustable timedelay on overload (L) and also the I2tramp characteristic (S). As shown(see diagram) these are essential toprovide selectivity when gradingwith other protective devices such asdownstream fuses and upstreamrelays. The standard ‘LSI’ curveprovides more than five millioncombinations of unique time currentcharacteristics.
Unlike the previous TemPower “AT”series, TemPower 2 “AR” ACBs havean identical rated breaking capacity,rated short-time withstand current,

Adjustable from 40–100 % of rated current. TrueRMS detection up to the 19th harmonic, a distantvision for the competition who rarely see past the7th. Neutral protection for all those Triple-Nharmonics, such as 3rd, 9th and 15th. Also in case we forgot to mention, a “thermal memory” as standard!
Reversed power trip function(S-characteristic)
This feature provides additional protection whenparalleling generators. The AGR21/22 OCR forgenerator protection with the reverse power tripfunction, negates the need for installation and wiringin an external reverse power relay. This feature isavailable using an AGR2 OCR with a specialgenerator “S” type characteristic only.

Two channel pre-trip alarmfunction (S-characteristic)
This function can be used to monitor and switch onadditional power backup to feed critical circuits. Forexample, the function can be set so that when a pre-tripalarm is activated, an emergency generator starts toensure a constant supply. This feature is only availableon some AGR21/22 OCR models with a generator “S”characteristic – refer features table pages 40-41.
N-phase protection function (optional)
In 3-phase, 4-wire systems that contain harmonicdistortion, the 3rd harmonic may cause largecurrents to flow through the neutral conductor. TheN-phase protection function prevents the neutralconductor from sustaining damage or burnout dueto these large currents. Available in all OCRs exceptfor generator “S” characteristic types.
Adjustable undervoltage trip function (UVT)
Available as a fixed type, or with adjustable voltagepick up and an adjustable time delay. 3 Phase, Phasefailure protection is also available. AGR11/21/22OCRs – refer features table pages 40-41.

Draw-out position indicators
This type of ACB consists of a breaker body and adraw-out carriage. The carriage is fixed into aswitchboard, and the breaker body can be inserted orremoved from the carriage via the racking in and outmechanism. There are stages or body positions in thewithdrawing out process. They are: CONNECTED, TEST,ISOLATED, and WITHDRAWN. The switchboard paneldoor can be kept closed during the CONNECTED, TEST,and ISOLATED stages (“shut-in three positions”).
Draw-out ACB Connection options
Carriage connection terminals
Three types of main circuit terminal arrangements areavailable. They are; vertical terminals, horizontal terminals,and front connect terminals. Additionally combinations ofvertical or horizontal terminal arrangements can bespecified for the line and load sides. Unless otherwisespecified by the user, horizontal terminals are standard ontypes AR208S, AR212S, AR216S and AR220S ACBs onboth the line and load sides. Vertical terminals arestandard on AR325S, AR332S and AR440S. Only verticalterminals are available for AR440S.
Control circuit terminals
• Terminal blocks (for auxiliary switches, position switches, and control circuits) are positioned on the top of the ACB front panel and can be easily accessed from the front for wiring purposes.
• M4 screw terminals are supplied on all control circuit devices. 0.5 mm-thick tab terminals are available on request.

Push-tab terminals (Optional) Screw terminals (Standard)
Both the main and control circuits are connected to the mainpower supply for normal service.
Both the main and auxiliary control circuits are fullyisolated. The switchboard door does not need to beopened.
The switchboard door can now be opened so the breakerbody can be fully withdrawn from the draw-out cradle.
Draw-out operation release buttonThe position indicator includes a safety “release button” which needs to be depressed to allow ACB insertion orwithdrawing from the carriage. When inserting the ACB, theracking-in action will be prevented once the ACB reaches the “test” position indicator. To allow further racking in, therelease button must be pressed. Similarly, when withdrawingthe ACB, further withdrawing will be prevented once the ACBreaches the test position. The button must then be pressed in to allow complete ACB withdrawal to fully “isolated” position.
The breaker body is fully withdrawn from the draw-outcradle.
The main power circuit is isolated,however the auxiliary control circuits remain connected. Thisposition permits operation testing without the need to openthe switchboard door.

Position switches
Position switches operate to give an indication of an ACBs status or position relative to the carriage. A position switch indicates the following positions: CONNECTED, TEST, ISOLATED, and INSERT. There are two contact arrangements: 2c and 4c. Connections to the switches are made screw terminals. Tab terminals are available as an option. The following table lists the switch types available.
Door interlock
The door interlock prevents the switchboard door from being opened unless the breaker body is in theISOLATED position. Only when the draw-out handle is removed from the ACB when the ACB is in theISOLATED position, is the door interlock released and the switchboard door allowed to open. When insertingthe ACB back into the carriage, the switchboard door must be closed once the breaker is in the ISOLATEDposition. When the door interlock is supplied a special draw-out handle is also supplied.Refer page 56 for draw out handle details.

For this type of ACB, the closing springs are charged by means of an internally mounted motor. ON/OFFoperation of the ACB can be performed remotely. A manual charging mechanism is also fitted to facilitateinspection or maintenance work.
A motor is used to charge the closing springs. When the closing springs are released to close the ACB, theyare automatically recharged by the motor for the next closing operation.
Turning on a “remote” ON switch enables the ACB to be remotely closed.
• Anti-pumping mechanismEven if the ON switch is kept on, the ACB closing operation is performed only once. To close the ACB again,turn off the ON switch to allow the motor to charge the springs, then activate the ON switch again.
• If ON and OFF signals are simultaneously given to the ACB, the ON signal is ignored.
(1) With an AGR-11 OCR or without OCR (Non Auto ACB).For opening the ACB remotely, specify a shunt trip device or an undervoltage trip.
(2) With an AGR-21 or AGR-22 OCR.By operating an external OFF switch, a tripping coil in the ACB called “TC” is activated, thereby opening the ACB. The “TC” tripping coil is fitted as standard.

34
The TemPower 2 over-current relay provides flexible protection functions within 3 different relay types: AGR-L L = General / Industrial & transformer protectionAGR-R R = Standard Inverse, Very Inverse, & Extremely Inverse curveAGR-S S = Generator / Marine protection type
In terms of features other than characteristic curves, AGR OCRs can be split into 3 general categories:Standard type: AGR-11 (L, R or S curve)Advanced type: AGR-21 (L, R or S curve)Advanced LCD display type: AGR-22 (L, R or S curve)AGR OCRs contain many overlapping features, meaning an OCR can be chosen for a particular application.
Protective functions
➀ Adjustable long time-delay trip function LT
RMS sensing is used to accurately read throughdistorted waveforms. In addition to the standard Land S-characteristics, the R-characteristic is availablewith five selectable characteristics in the long timedelay trip region. The R-characteristic can be used toprovide selectivity with other devices such as circuitbreakers or fuses. (refer page 10).
HOT start mode (applicable to the L-characteristic)
HOT or COLD start mode is user-selectable. Inresponse to an overload, when the OCR is the HOTstart mode, the OCR operates faster than when in theCOLD start setting. This OCR when switched to startin HOT mode provides extra protection, because ittakes into account that the load may be alreadyheated and the greater level of existing heat stress inthe system.
➁ Adjustable short time-delay trip function ST
The ST delay trip function has a "definite time delaycharacteristic" and "ramp characteristic". Thesecharacteristics are switch selectable on or off. Thisramp characteristic provides useful adjustabilitywhen seeking to obtain selectivity between anupstream ACB and downstream circuit breakers orfuses. In OCRs with an L/R characteristic, when a faultcurrent exceeds 10 times the rated current (In), theramp mode will be changed to the definite timemode. (5 times rated current for "S" type OCRs)
➂ Adjustable instantaneous trip function INST/MCR
There are two modes of instantaneous tripping. Theyare the INST and the MCR setting. Either function canbe selected by operating a switch on the OCR. The INST (instantaneous) trip function trips the ACBwhen a short circuit current exceeds its pickup currentsetting, irrespective of whether the ACB is closing orhas already closed. Alternatively, the Making CurrentRelease (MCR) trips the ACB when only if the shortcircuit current exceeds the pickup current settingduring the closing operation. After the ACB is closedthe MCR is inoperative. Note:The MCR requires separate control power. Should thisfail, the MCR will be inoperative. Power must either bereturned to the MCR or the OCR must be switched tothe INST trip position to obtain any instantaneous tripfunction.

➃ Adjustable pre-trip alarm function PTA
A single channel pre-trip alarm function provides analarm signal via the alarm contact (1N/O-contact).This signal occurs when the load current exceedinga pre-determined value lasts for a pre-determinedtime. The pre-trip alarm is automatically reset whenthe load current drops back to the pre-determinedvalue.A 2-channel pre-trip alarm function is also availablefor generator S-characteristic OCRs. This functioncan be used to adjust load feeding by order ofpriority. Note; both 1 & 2 channel types require acontrol power source.
➄ Ground fault trip function GF
The GF pickup current can be set between 10 % and 100 % of the CT rated primary current [ICT].
Altering ramp characteristics:The ramp and definite time characteristics are switchselectable. The GF trip function comes into operationwith the definite time characteristic when the loadcurrent reaches 100 % or more of the CT ratedprimary current [ICT]. The GF trip function is factory-set to a definite time characteristic. When using a 3-pole ACB in a 3-phase, 4-wiresystem, an external neutral CT for the neutral linemust be used, refer page 35.
Notes: 1: The GF trip function comes with operation output contacts and indication LEDs. If only ground fault indication is required, but noACB tripping function, please specify at the time ofordering.
➅ Reverse power trip function RPT
(For AGR-21 and AGR-22 only.)The RPT function protects 3-phase generatorsrunning in parallel against reverse power. The RPTpickup current can be set at any one of sevenincrements from 4 % to 10 % of the generators ratedpower. The applicable rated voltages are AC100 -120 V, AC200 - 240 V, and AC380 - 460 V. The RPTfunction comes usually with LED operation indicationand contact output.
Notes: 1: CT for RPT is not available for AR440S, 4000 AACBs.2. Indent item. Contact NHP for details.
➇ N-phase protection function NP
This NP function is available on 4-pole ACBs andprevents the neutral conductor from sufferingdamage or burnout due to overcurrent. The NP trippickup current can be set between 40 % and 100 %of the OCR rated primary current for OCRs witheither L or R-characteristics. The pick-up current isfactory set to a value specified at the time ofordering.
Notes: 1: The NP trip function comes as standard with LEDoperation indication and an output contact. The NPtrip pick-up CURRENT and trip TIME settings are afunction of the position of the OCRs LT trip functiondial. Note. The N phase protection option is notavailable for generator "S" type OCRs. 2: Indent item. Contact NHP for details.

➈ Adjustable undervoltage trip function UVT
(For AGR-21 and AGR-22 non-communication modelsonly.)AGR21/22 Phase failure protection is achieved byconnecting and monitoring all 3 phases.The UVTs are available in 4 models that can monitordifferent line voltages. They are: 100/120 V AC,200/240 V AC, 380/460 V AC, and 24 V DCThe UVT function trips the ACB when the UVTcontrol voltage drops to a value equal to 65 % of therated value. The operating time can be set at any oneof ten settings: Instantaneous trip through to a 1sdelay. The ACB can be closed 2 seconds after theUVT control voltage has returned to the pick-upvoltage.
Notes: 1: UVT control power is shared by the reverse powertrip function (if fitted).2: The UVT has LED operation indication and acontact output.3: It should be noted that the AGR11 OCR UVToption provides a UVT that responds to acontrol voltage signal obtained from any one of 3phases, rather than by monitoring all 3 phases. Asmentioned above, AGR21/22 OCRs will provide UVTdetection for all 3 phases.4: For "fixed" undervoltage trips as used on ACBswith AGR11 OCRs, or Non Auto ACBs(no OCR fitted) Refer to page 33.
NON setting and fail-safe feature
NON settingBy setting certain OCR setting dials to the "NON"position the corresponding protection functions canbe rendered inoperative. Those functions are: LT, ST,INST/MCR, and GF. The appropriate use of NONoperation setting can be a useful means for obtainingselectivity.
Fail-safe featureTemPower 2 OCRs come with fail-safe features if theOCR setting dials are improperly set to a NONoperation position.
If the ST and INST trip pickup current setting dialsare both set to NON, the fail-safe mechanism willactivate the INST trip function to trip the ACB when afault current equal to or more than 16 times the ratedcurrent [In] flows through the ACB. If the ST and MCR trip pickup current setting dialsare both set to NON, the fail safe mechanism willactivate the ST delay trip function to trip the ACBwhen a fault current equal to or more than 10 times(5 times for generator protection) the rated current[In] flows through the ACB.

Function: Checking the current and time settings foran overcurrent tripping relay Long time delay trip Ground fault trip
Short time delay trip Pre-trip alarm
Instantaneous trip
Applicable models: All models of OCRs for AR typeACBs Since an OCR can be powered from the checker,the OCR can be measured even if no control poweris applied to the OCR. The connection with an OCR can be made easilyusing a single connector. The function, output phase, output voltage, andtrip signal for the OCR during the testing areindicated on the LCD and with the LEDs. All theoperations can be performed easily usingpushbutton switches.Function of each switchThe function of each switch is described below:Fig. 1 illustrates the front panel of the checker. Thenumber preceding each switch corresponds to thenumber indicated in this figure.1 POWER switchThis switch is used to turn ON/OFF the checker.When the built-in battery is active, the switch isautomatically turned OFF (auto-OFF function) after ithas not been pressed for 1 minute or more.2 SELECT FUNCTION switch
This switch is used to select a measurement mode.Pressing this pushbutton switch toggles in the aboveorder and each measurement mode is indicatedboth on the LCD screen and corresponding LEDs onthe OCR checker. (fig. 1).If the measurement mode is changed, the outputphase is maintained, but the output voltagebecomes 0 V.3 SELECT PHASE switchThis switch is used to select a signal output phase.It is not valid during signal output. Even if theoutput phase is changed, the directly previousoutput voltage is maintained. This feature isconvenient when the same measurement isperformed continuously.
4 and 5 SIG. ADJUST UP/DOWN switchesThese switches are used to increase/decrease theoutput voltage value. A rough adjustment can bemade by holding down each switch and fine tuningcan be performed by pressing each switch. Theoutput value can be adjusted during output.6 OUTPUT switchThis switch is used to turn ON/OFF the voltageoutput. When a voltage value is output, the voltagevalue indicated on the LCD changes from a blinkingstate to an illumination state.4.2 Measurement procedure in the ST mode
The setting value and measurement procedure inthe ST mode are given below.Measurement of pickup current setting in the STmodeI. Press the SELECT FUNCTION ( 2 in Fig.1) andselect “ST P.U” on the LCD and with the LED.II. Using the SELECT PHASE switch ( 3 in Fig.1)select the phase to be measured.III. Press the OUTPUT switch ( 6 in Fig. 1) to outputthe voltage.IV. Press the SIG. ADJUST UP ( 4 in Fig.1 ) toincrease the voltage until tripping occurs. Whentripping occurs, the LED changes from a blinkingstate to an illumination state and “TRIP” appears onthe LCD indicating the voltage value at whichtripping has occurred. The output is automaticallycut with the trip signal.Measurement of time delay in the ST modeI. Press the SELECT FUNCTION switch ( 2 in Fig. 1 )and select “ST T” on the LCD and with the LED.II. Using the SELECT PHASE switch ( 3 in Fig. 1 )select the phase to be measured.III. Press the SIG.

Key lock
Two types of key locks are available, one that canlock the ACB in the closed position, and another forthe open position. When an ACB is fitted with a keylock, the operator cannot operate the ACB unlessusing a matched key.
Key types
NHP can fit the following lock types to TemPower 2ACBs: > L & F / Fortress
> Ronis> Castell
Unless specified otherwise, NHP will supply ACBsfitted with the Fortress type H31 lock device. A key isincluded. Multiple numbers of keys can be supplied,or even no keys on request. NHP can also supplylocks keyed to specific codes on request.
Note: Key locks, Off Padlocks and Key Interlocksoccupy the same mounting space on an ACB.Therefore only one can be fitted at any time. Offpadlock – page 56.
Key interlock
Key interlocking is a system of interlocking betweenACBs, with each ACB fitted with a key lock designedto lock the ACB in the OFF (contacts open) position. A key must be inserted to release the lock before
the ACB can be closed.
The ACB must be opened and locked in the OFF position before the key can be removed.
The other ACB that is not locked OFF can now be closed.
By utilising the ACB lock OFF key lock feature, andby providing users with a limited number of keys,this method by default provides an effective andreliable interlock system. Using the same keys alsoallows interlocking between an ACB and otherdevices (such as a switchboard door).
Note: Key locks, Off Padlocks and Key Interlocks occupy the samemounting space on an ACB. Therefore only one can be fitted atany time. Off padlock – page 56.

Mechanical interlock
TemPower 2 mechanical interlocks employ either cable or rod systems to provide positive interlockingbetween two or three ACBs. To further enhance the system, electrical interlocking can be used. Mechanical interlock types 2 way cable interlock for 2 ACBs
3 way cable interlock for 3 ACBs
2 way vertical side mounting rod interlock for 2 ACBs
3 way vertical, available as either a rod or cable type for 3 ACBs
1 CABLE Interlocking – horizontal, vertical or diagonal
Cable interlocking is the most flexible means of interlocking ACBs in terms of combinations and mountingflexibility. Cable Interlocking is possible between any 3 or 4 pole frame size or combination of different framesizes within the TemPower 2 range. This is achieved through the use of cable as the form of interlock. ACBscan be mounted diagonally, horizontally or vertically. Cable interlocking can be used to obtain a variety of switching combinations between 2 or 3 ACBs.• The simplest is between two ACBs using 2 cables. Either ACB "X" or "Y" can be closed. (Type C)• In the case of 3 ACBs, called "X", "Y" and "Z", by using 4 cables, interlocking can be obtained
between X and Y, Y and Z, but not X and Z. (Type A)• By using 6 cables, interlocking can be obtained
between "X", "Y" or "Z" in any combination. (Type B)
Distance between ACBs & Cable lengthCable lengths, or the distance the ACBs are apart can bespecified by customer order. Special pre-specifiedlengths can range from 1 m up to 7 m. Otherwise NHP will supplya “kit” consisting of two 3 meter cable lengths that can be cut tothe required length by the user. Multiple cable quantities can beordered for A & B interlocking.Bend radiusThe bend radius it the minimum diameter bend allowed thatmaintains functionality. If the bend is less than 150 mm, the cable can jam against the outer protective sleeve. The cable consists of a solid stainless steel wire inside a protective sleeve.
2 Vertical ROD interlocking
Rod interlocking is possible between any 3 or 4 pole frame size or combination ofdifferent frame sizes within the TemPower 2 range. Rod interlocking is for mountingACBs vertically above one another only. The minimum pitch can be 550 mm, the maximum 1200 mm. For any two ACBsthat require an exact pitch distance, please specify when ordering.
Rod interlocking can be used to obtain interlocking between 2 or 3 ACBs.• The simplest is between two ACBs. Either ACB "A" or "B" can be closed. • In the case of 3 ACBs, called "A", "B" and "C", interlocking can be
obtained between A and B, C and B, but not A and C. Contact NHP for additional details.

An ACB used as a mains earthing device
An earthing ACB is primarily a safety device forpersonnel performing electrical maintenance. When“live” main switchboards or associated downstreamdistribution systems require maintenance ormodification, it is a critical requirement that safeworking conditions exist for people, and thatelectrical equipment is protected.
ApplicationDuring a typical maintenance period, the switchboardsection being worked on will be isolated, or perhapsthe whole switchboard. There is always a risk that anunauthorised person may switch the power supplyback “ON”, which could have lethal results.Even though it is possible to lock switching devices“OFF” to ensure that voltage is not applied to thecircuit section being maintained, absolute safety canbe maximised only if that particular section isSOLIDLY EARTHED during the maintenance period.
A safe and relatively economical way to applysystem earthing during routine maintenance is via adedicated ACB that acts as an earthing path. TheACB would have a short circuit rating equal to thesystem potential fault level. An earthing ACBeffectively replaces the use of not so reliable safetydevices such as cables with “Alligator clips” etc beingused to connect busbar and other live parts to earthduring maintenance. To further clarify the point, an earthing ACB does not switch the main power off. Power is alreadyswitched off further upstream. An earthing ACBsimply acts as a solid, reliable, path for a potentialearth fault current. Terasaki have designed a rangeof TemPower 2 ACBs for system earthing applications.Either the incoming cables or busbars to theswitchboard can be grounded (figure 2) or the mainbusbars on the load side of the ACBs only (figure 1).

The modified TemPower 2 ACB - Earthing device (continued)
NHP can supply a completely modified dedicatedearthing ACB, parts and advice for on-siteconversion. The modified ACB is always awithdrawable type with modifications to the carriageand the ACB. The switchboard itself requires apermanent special earth connection to the earthingACB carriage. The modified earthing ACB includeseither a line or load phase shorting bar, and an earthterminal. The ACB carriage is fitted with a dedicatedearth terminal, which has a cluster connection similar
the main phase connections. If the ACB has an OCR,shunt trip or UVT, then they must be disabled whilethe breaker is acting as an earthing device. Howeverin most applications NHP will supply a breaker whichis "Non Auto". That is, there is no OCR, and becausethese are earthing breakers, no shunt or UVTs. Thestandard ACB "position indicator" is also modified togive the ACB two mechanically operated positionindicators, called "ISOLATED" and "EARTHCONNECT".
Obtaining the ACB from NHP or converting on site
NHP can supply a completely modified dedicatedearthing ACB or if an existing breaker that is on siterequires converting, some parts and instructions canbe supplied. Though the conversion of an existingstandard breaker can be performed on site, it isprobably more economical and practical to have amodified ACB on standby for regular use as an
earthing device. This is because making and thenundoing the modification will take a number ofhours, possibly using up valuable shutdown time.The carriage however is not such an issue, becauseonce modified for earthing applications it can beused with either a standard ACB or the modifiedearthing ACB.
Using the earthing ACB
When the ACB body that has the earthingmodifications is inserted into the earthing chassis, itmust be racked into the "EARTH CONNECT" position.Switching the ACB "ON" will then apply a solid earthto the system. Figs 1 and 2 (previous page) show anACB with incoming cables earthed and theswitchboard busbars earthed respectively. It is vitalthat the ACB cannot be tripped by unauthorizedpersonnel during the maintenance period. In fieldconverted ACBs where an OCR and shunt may befitted, in order to prevent the a trip occurring underany circumstances, the fitting of an earthing devicewill automatically make the OCR and shunt tripinoperative. This is achieved by shorting out the OCRcurrent transformer terminals and open circuiting theshunt trip. There is also a padlockable shutter overthe mechanical trip button. It is also not safe toinclude an under voltage trip (UVT) on an earthing
ACB, as the loss of control supply would cause theACB to trip. It is always possible that an unauthorized personmay switch "ON" an alternate feed into the sectionreceiving maintenance. In such cases it is necessaryfor the earthed ACB to remain solidly closed duringthe duration of the earth fault short circuit. This is sothat the other supply ACB will trip via its own OCR. It is for this reason the ACB and associated earthingconnections must have a short-time rating equal tothe system fault level. TemPower 2 earthing deviceshort time ratings are available on request from NHP. Following the completion of maintenance work, theearthing ACB can be removed. The same ACB can be left for further use, or have the earthingmodifications removed. A standard ACB can beinserted into the same carriage for normal service.

Altitude Below 2000 m
Atmosphere Excessive water vapor, oil vapor, smoke, dust, or corrosive gases must not occur. Sudden changes in temperature, condensation levels, or icing-up will affect the operation of the ACB.
For operating temperatures higher than those shownabove, refer to the temperature derating or busbarconnection chart found on page 81-86, or contactNHP with special requirements.

Example of an equipment enclosure climate control system using COSMOTEC/STEGO
products
Warning lamp(Sirena)
GNF grill and filter ventsthe warm air out of the enclosure (Cosmotec)
ThermostatsFZK 01140 switches thewarning lamp (Cosmotec)
KTS 01141 switches theGNV fan at the settemperature
KTO 01140 regulates theoperating temperature ofthe heater
HG PTC heater prevents condensation in theenclosure (Stego)
GNV fan, grill and filterdraws the cooler externalair into the enclosure andcools the internalequipment (Cosmotec)
COSMOTEC / STEGOStandard AR ACBs can operate without specialtreatment up to a relative humidity of 85 %. Formoisture conditions above this, other options suchas dehumidifiers, heating systems, fans and airconditioners, can be used to control theenvironment within a switchboard.Controlling the ambient temperature within thewhole switchboard may often be a preferablesolution compared to special “moisture proofing” or“cold climate” treatment of individual componentssuch as circuit breakers.For a wide range of cabinet cooling and heatingsystems, the NHP COSMOTEC & STEGO productrange could be considered. COSMOTEC & STEGOproducts are supported and stocked by NHP.COSMOTEC & STEGO products can be found in theNHP Part A catalogue.

The busbars to the ACB should be firmly supported near the ACB terminal. Fault current flow through thebusbars develops a large electromatic force between the busbars, and the support must be strong enoughto withstand such forces. The ACB terminals should not be relied upon as a busbar support.

In such an installation, reduction of the rated current of the ACB (derating) is necessary since ventilation isusually poor and because of the existence of other heat generating devices such as busbars.The degree to which ACB derating is necessary depends upon the size and arrangement of busbars and ACBconnections, the size of the switchboard compartment where the ACB is mounted, the switchboard enclosuresize, the degree of the enclosure ventilation, as well as other environmental factors.The following tables can be used as a general guide to rating ACBs in an enclosure. It is possible however thatvarying conditions or the addition of other heat producing devices or even obstructions within the enclosuremay require additional derating or an increased level at ventilation.As a guide for ACB derating, the rated current data is shown here for typical switchboard compartments, andthe data is based on the temperature rise limits specified below.
The following tables indicate the rated currents for ACBs when the enclosure internal temperature is unknown,but the external temperature is known. This data is based on the results of temperature tests carried out byinstalling AR ACBs into an enclosure 2300H x 700W x 1000D.The following is a typical example: ACB type: AR216S (1600 A) with horizontal terminals ACB position: Top, when 3 ACBs are installed vertically Ventilation area: 2400 cm2 for both the ACB and busbar zone (cut-out or vent size) Zone ventilation: Referring to the diagrams below, in this case the ventilation can be front or rear Outside temperature: 50 ºC

Result: The derating required for the AR ACB is 50 A, which reducesthe breaker to a 1500 A capability. By way of example, this derating issubstantially less than that which would have been required for theequivalent previous Terasaki series “AT” ACB (1330 A)
