Masterpact: presentation
Masterpact circuit breakers are the product
of Merlin Gerins 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 circuit
breakers. In particular, they require nopreventive maintenance.
ease of installationMasterpact is a complete and rationallydesigned range.c10 ratings;c4 breaking-capacity levels;c6 control units;ca complete range of auxiliaries andaccessories;
cnumerous versions (three and four-poledevices, fixed and drawout versions, etc.).
Masterpact circuit breakers are easy toincorporate in switchboards.ca single frame size from 800 to 3200 A,
thus making for standardised columns;can upper safety clearance equal to zerodue to the arc-chute cover, on both the fixedand drawout versions;cbuilt-in measurement functions in thecontrol units;cauxiliaries are the same for the entirerange and may be easily implemented (onlya screwdriver is required).
Masterpact circuit breakers are easy to
connect to the main distribution system.
call types of connections are available(horizontal and vertical terminals, front andmixed connections);cconnections are possible with bars of anythickness;cconnection to the input power source is
possible 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:ctotal time discrimination on the N1 and H1circuit breakers and maximum discrimination
on H2 circuit breakers;cfactory pre-setting of Masterpact circuitbreakers which never require any periodicmaintenance;chigh electrical endurance: 10 000 cycles at1600 A and 30 cycles at 50 kA, withoutmaintenance;cpreventive indications: load-sheddingindication switch, long-time thresholdoverrun alarm, etc.;ceasy access to the main contacts fitted
with mechanical wear indicators. An optionalfunction on the STR68 control unit is theremote indication of contact wear, thus
making possible continuous monitoring ofcircuit breakers during their service life.
operating safetyThe insulating casing of Masterpactcircuit breakers provides for:cuser safety:vdouble insulation on the front face(class II),vauxiliary circuits in a compartmentinsulated from the power circuits;cswitchboard safety when the circuitbreaker is in the open position:
veach pole is effectively isolated in its ownhousing,vlimitation of external disturbances.
Positive contact indicationThe position indicator cannot indicateopen unless the poles are effectively
separated by the required distance.The circuit breakers automatically open
during racking in and out.
reliabilitycMasterpact 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;cthe design of Masterpact circuit breakers
is modular with delayed differentiation(highest possible number of common partson all models). The result is shorter deliverytimes and enhanced reliability.

Masterpact circuit breakers comply with allthe major international standards:
cInternational standard IEC 947-2;
cNorth American standards (please consult
us):UL 489, ANSI C37-50, CSA C22-2,NEMA AB1 et SG3;
cJapanese standards: JIS 160 and C 8372.
They also comply with the following national
standards:
cFrance NF C 63-120;
cGermany VDE 0660;
cUnited Kingdom BS 4752;
cAustralia AS ;
cItaly CEI.Masterpact circuit breakers comply with the
specifications 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 are
unchanged, but the new standard providesthe user with a better guarantee concerningquality and performance.Circuit breakers are subjected to tests thatare more representative of real operating
conditions.IEC 947-2 also clarifies the notion ofbreaking capacity.
cIcu :the ultimate breaking capacity, whichmust be greater than or equal to the 3-phase
short-circuit current at the point ofinstallation of the circuit breaker, a value
unlikely to be reached under real conditions;cIcs :the service breaking capacity,generally expressed as a percentage of the
ultimate 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 normally
after having interrupted a current equal toIcs several times;
cIcw :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:
csuitability for isolation recognised for
circuit breakers having passed specialelectrical and mechanical tests;
cindustrial earth-fault circuit breakerscovered by an appendix;
cdefinition of tests designed to ensure
coordination between two circuit breakers.
conformity with standards
tropicalisationAs standard, Masterpact circuit breakerscomply with NF C 63-100 standard level 2
conditions (95 % relative humidity at 45 Cor 80 % at 55 C, hot and humid climateconditions). They also comply with thefollowing standards:
cIEC 68-2-30 damp heat;
cIEC 68-2-2 dry heat;cIEC 68-2-11 salt spray;cIEC 68-2-1 low temperatures during
storage.Corrosive atmospheres: Special grease or
other 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 are
equipped with microprocessor-basedelectronic control units.
All the protection functions are powered by
the 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.

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

In addition, three bargraphs provide animmediate visual indication of the load oneach of the three phases.

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 a
downstream 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. In
the 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 releases
cinstantaneous (MN)This release instantaneously opens thebreaker when its supply voltage drops below
a 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 have
no effect on the main contacts.Closing is possible when the release voltagereaches 85 % of its rated value.
ctime 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 by
fault trip or by manual or electrical operation,anti-pumping is provided by requiringcancellation of the initial closing command
before reclosure of the breaker is possible.The closing release is supplied on requestwith the manual operating mechanism
