safety and reliabilityc reduced, simple maintenance (maincontacts easily accessible, with wearindication feature);c double insulation from the front face;c positive contact indication;c auxiliary devices can be fitted on sitewithout adjustment;c fewer parts than conventional ranges (by afactor of 5-10);c a trip interlock ensures that the circuitbreaker is open during connection anddisconnection;c connection to top or bottom terminals;c fully tropicalised as standard.
stored energy operatingmechanismMasterpact circuit breakers are operated viaa stored energy mechanism forinstantaneous opening and closing.The mechanism is charged either manuallyor electrically. Closing and openingoperations can be initiated either from thelocal pushbuttons on the circuit breaker frontface, or by remote control.
common auxiliariesfrom 800 A to 6300 AAuxiliariesc accessible from the front, mounted in aseparate compartment insulated from powercircuits;c secured by a single screw;c adjustment-free;c can be fitted on site.
ccccc Source changeover systemFour solutions are available:v mechanical interlocking for 2 or 3 circuitbreakers, adaptable to various source-changeover configurations;v automatic source-changeover controller,easy to implement on any two suitablyequipped circuit breakers (electricallycharged operating mechanism, etc.) (for 3circuit breakers, consult us);v complete assembly including 2 or3 mechanically (rod assembly) interlockedcircuit breakers, adaptable to varioussource-changeover configurations;v complete assembly including2 mechanically (rod assembly) interlockedcircuit breakers and an automatic source-changeover controller, adaptable to varioussource-changeover configurations. Readyfor connection.
other possibilities ccccc Fixed circuit breakerThe fixed circuit breaker is derived from themoving part of the drawout circuit breaker byadding a fixing bracket on each side.
ccccc Switch versionThe switch (unprotected) version is deriveddirectly from the standard circuit breaker, butdoes not implement a control unit (or themagnetic trip units used with the DC circuitbreakers). Available models are:v standard: type HI and NI;v high performance: type HF, equipped witha protection system that instantaneouslyopens the circuit breaker in the event ofclosure under fault conditions.
ccccc Earthing switchA special short-circuit and earthing switch isavailable on request for the M08 to M32Hdrawout types, 3 or 4 poles. Please consultus.

Masterpact: presentation
Masterpact circuit breakers are the productof Merlin Gerin’s vast experience in the fieldof power circuit breakers. They incorporateall the qualities of traditional air circuitbreakers while drawing on certain of theadvantages specific to moulded-case circuitbreakers. In particular, they require nopreventive maintenance.
ease of installationMasterpact is a complete and rationallydesigned range.c 10 ratings;c 4 breaking-capacity levels;c 6 control units;c a complete range of auxiliaries andaccessories;c numerous versions (three and four-poledevices, fixed and drawout versions, etc.).
Masterpact circuit breakers are easy toincorporate in switchboards.c a single frame size from 800 to 3200 A,thus making for standardised columns;c an upper safety clearance equal to zerodue to the arc-chute cover, on both the fixedand drawout versions;c built-in measurement functions in thecontrol units;c auxiliaries are the same for the entirerange and may be easily implemented (onlya screwdriver is required).
Masterpact circuit breakers are easy toconnect to the main distribution system.c all types of connections are available(horizontal and vertical terminals, front andmixed connections);c connections are possible with bars of anythickness;c connection to the input power source ispossible on the upper or lower terminals ofthe circuit breakers.
Due to their small size, Masterpact circuitbreakers can replace most existingcircuit breakers.
continuity of serviceMasterpact circuit breakers are designedwith continuity of service in mind. Theresult is:c total time discrimination on the N1 and H1circuit breakers and maximum discriminationon H2 circuit breakers;c factory pre-setting of Masterpact circuitbreakers which never require any periodicmaintenance;c high electrical endurance: 10 000 cycles at1600 A and 30 cycles at 50 kA, withoutmaintenance;c preventive indications: load-sheddingindication switch, long-time thresholdoverrun alarm, etc.;c easy access to the main contacts fittedwith mechanical wear indicators. An optionalfunction on the STR68 control unit is theremote indication of contact wear, thusmaking possible continuous monitoring ofcircuit breakers during their service life.
operating safetyThe insulating casing of Masterpactcircuit breakers provides for:c user safety:v double insulation on the front face(class II),v auxiliary circuits in a compartmentinsulated from the power circuits;c switchboard safety when the circuitbreaker is in the open position:v each pole is effectively isolated in its ownhousing,v limitation of external disturbances.Positive contact indicationThe position indicator cannot indicate«open» unless the poles are effectivelyseparated by the required distance.The circuit breakers automatically openduring racking in and out .
reliabilityc Masterpact circuit breakers comprise tentimes fewer parts than traditional devices.They are easier to produce and morereliable.c the Masterpact circuit-breaker factory iscertified ISO 9002;c the design of Masterpact circuit breakersis modular with delayed differentiation(highest possible number of common partson all models). The result is shorter deliverytimes and enhanced reliability.

Standardised characteristics indicated onthe rating plate:Ui: rated insulation voltageUe: rated operational voltageIcu: ultimate breaking capacity, for variousvalues of the rated operational voltage UeIcs: service breaking capacityIcw: short-time withstand current
: suitable for isolation
Masterpact circuit breakers comply with allthe major international standards:c International standard IEC 947-2;c North American standards (please consultus):UL 489, ANSI C37-50, CSA C22-2,NEMA AB1 et SG3;c Japanese standards: JIS 160 and C 8372.
They also comply with the following nationalstandards:c France NF C 63-120;c Germany VDE 0660;c United Kingdom BS 4752;c Australia AS ;c Italy CEI.Masterpact circuit breakers comply with thespecifications of the marine classificationcompanies (Veritas, Lloyd's Register ofShipping, Det Norske Veritas, etc.).
IEC 947-2This standard replaces IEC 157-1,applicable since 1973.The circuit breaker selection criteria areunchanged, but the new standard providesthe user with a better guarantee concerningquality and performance.Circuit breakers are subjected to tests thatare more representative of real operatingconditions.IEC 947-2 also clarifies the notion ofbreaking capacity.c Icu : the ultimate breaking capacity, whichmust be greater than or equal to the 3-phaseshort-circuit current at the point ofinstallation of the circuit breaker, a valueunlikely to be reached under real conditions;c Ics : the service breaking capacity,generally expressed as a percentage of theultimate breaking capacity (25, 50, 75 or100 % of Icu). It corresponds to a short-circuit current that is more likely to bereached under real conditions. The circuitbreaker must continue to operate normallyafter having interrupted a current equal toIcs several times;c Icw : short-time withstand current forcircuit breakers belonging to category B(category B refers to circuit breakers withtime discrimination and category A to thosewithout time discrimination).Furthermore, IEC 947-2 takes into accountrecent technological advances:c suitability for isolation recognised forcircuit breakers having passed specialelectrical and mechanical tests;c industrial earth-fault circuit breakerscovered by an appendix;c definition of tests designed to ensurecoordination between two circuit breakers.
conformity with standards
tropicalisationAs standard, Masterpact circuit breakerscomply with NF C 63-100 standard level 2conditions (95 % relative humidity at 45 °Cor 80 % at 55 °C, hot and humid climateconditions). They also comply with thefollowing standards:c IEC 68-2-30 damp heat;c IEC 68-2-2 dry heat;c IEC 68-2-11 salt spray;c IEC 68-2-1 low temperatures during
storage.Corrosive atmospheres: Special grease orother surface coatings available (pleaseconsult us).
pollution degreeMasterpact circuit breakers are certified foroperation in pollution degree IVenvironments as defined byIEC standard 947 (industrial environments).

Masterpact: functions and characteristics
control unit selection
Masterpact M08 to M63 circuit breakers areequipped with microprocessor-basedelectronic control units.
All the protection functions are powered bythe AC system and no auxiliary powersupply is required. The same is true for mostof the complementary functions.
Each control unit of the Masterpact rangecorresponds to a certain type of application(instantaneous, distribution, selective,universal).All the STR control units measure the truerms value of the current and are thereforenot affected by harmonics that may bepresent on the system.

This earth fault protection is designed toprotect the installation against the risks offire due to high earth faults (not to beconfused with schemes designed for theprotection of persons against electricalshock).Two types of earth protection are availablefor Masterpact:c residual current type (T): the control unitcalculates the vector sum of the phase andneutral (if distributed) currents;c source ground return type (W): the controlunit acts directly on the signal received froman external current transformer installed onthe source earthing circuit.

A number of circuit breakers areinterconnected one after another by a pilot-wire. In the event of a short-time or earthfault, the control unit applies the set timedelay only if it receives a signal from adownstream circuit breaker. If not, it tripsinstantaneously (tripping time as 0.1 short-time setting). In this way, the fault is clearedrapidly by the nearest circuit breaker. Thethermal stresses in the installation areminimised while maintaining timediscrimination throughout the entire
installation.Opto-electronic outputsThe use of opto-transistors ensures totalisolation between the internal circuits of thecontrol unit and the circuits wired by theuser.
Other information that can be transmittedincludes the value of the interrupted current,the state of the thermal memory and themaintenance indications
c indication of type of fault (F);
c segregated alarm switch for selectedfault type (V) , wired in parallel with theopening button (MX), it disables circuitbreaker closing for the selected type of fault.

Shunt release (MX)This release instantaneously opens thebreaker when energised. The supply can bemaintained or automatically disconnected. Inthe latter case, the user can series connectan internal auxiliary contact (OF).
releasesTwo types of voltage releases can be usedfor remote opening of Masterpact circuitbreakers.
Undervoltage releasesc instantaneous (MN)This release instantaneously opens thebreaker when its supply voltage drops belowa value between 35 % and 70 % of its ratedvoltage.If the release is not energised, the breakercannot be closed (either manually ofelectrically). Any attempt to close will haveno effect on the main contacts.Closing is possible when the release voltagereaches 85 % of its rated value.c time delayed (MNR)To prevent the breaker tripping in the eventof transient voltage dips, this release has abuilt-in time delay.A special version, available on request,allows instantaneous tripping (from amushroom-head emergency off button) bythe wiring of an external contact.
closing release (XF)This device releases the breaker closingmechanism when the spring is charged.Energisation can be maintained, as theclosing release provides an antipumpingfunction.
Note: anti-pumping function:After the breaker has been opened, either byfault trip or by manual or electrical operation,anti-pumping is provided by requiringcancellation of the initial closing commandbefore reclosure of the breaker is possible.The closing release is supplied on requestwith the manual operating mechanism

automatic source-changeover systemscontroller option selection (cont.)
controller UA Controller UA can be used with Masterpactcircuit breakers to implement a source-changeover system offering the followingautomatic functions:c switching from one source to anotherdepending on the presence of voltage UNon the "Normal" source;c control of an engine generating set;c shedding and reconnection of non-prioritycircuits;c switching to the "Replacement" source inthe event of a failure on one of the phases ofthe "Normal" source.
Electrical characteristicsPower is supplied from the auxiliaries controlplate ACP. The same voltage must be usedto supply the ACP plate, the IVE unit and thecircuit breaker motor mechanisms. If thisvoltage is the same as the source voltage,the "Normal" and "Replacement" sourcescan be used directly for the power supply. Ifnot, a BC type or equivalent isolationtransformer must be used.
Control voltagesc 220 to 240 V 50/60 Hz;c 380 to 415 V 50/60 Hz - 440 V 60 Hz.
Operationc a four-position switch can be used toselect:v automatic operation;v forced operation on source N;v forced operation on source R;v stop (circuit breakers open and manualoperation);c adjustment of time delays in front:v t1 from 0.1 to 30 seconds;v t2 from 0.1 to 240 seconds;v t3 from 0.5 to 30 seconds;v t4 from 0.5 to 30 seconds;v t5 from 60 to 600 seconds;c circuit breaker status indication on thefront of the controller: on, off, fault trip;c test button on the front of the controllerto check the transfer from the “Normal”source to the "Replacement" source and thereturn to the "Normal" source;
c integrated terminal block for connection ofthe following signals:v inputs:– order for voluntary transfer to source R(e.g. energy management commands),– supplementary control contact: (notcarried out by the controller). Transfer to"Replacement" source only if contact closed(ex: UR frequency control),v outputs:– control of engine generator set,– load shedding of non-priority circuits,– indication of operation in automatic mode;c 3 switches provide the following functions:v selection of the type of "Normal" source,i.e. single-phase or three-phase;v enable or disable voluntary energymanagement transfer if the "Replacement"source is not operational;v selection of the maximum toleratedstarting time for the engine generator set("Replacement" source): 120 s or 180 s.
Batibus option for controller UAA communication function can be used tocheck the following from a remote location:c status of the circuit breakers (open,closed or fault trip);c voltage presence on the “Normal” and“Replacement” sources;c presence of an order forcing operation onthe “Replacement” source (e.g. for energymanagement purposes);c values of settings and configurations,c status of the non-priority circuits (whethersubject to load shedding or not).
In automatic mode, this communicationsoption also offers the possibility of remoteforced operation on the “Replacement”source.

Certain distances must be maintainedbetween a circuit breaker and otherelements such as panels, bars and othercircuit breakers. Taken together, thesedistances form the safety clearance for thecircuit breaker. The diagrams and the tablebelow indicate the required distances wheninstalling Masterpact circuit breakers.
These distances are the results of testscarried out in accordance with standardIEC 947-2 and are in part determined by theultimate breaking capacities.
