Ambient temperatureMasterpact devices can operate under the following temperature conditions:c the electrical and mechanical characteristics are stipulated for an ambienttemperature of -5° C to +70° C;c circuit-breaker closing is guaranteed down to -35° C;Storage conditions are as follows:c -40 to +85°C for a Masterpact device without its control unitc -25°C to +85°C for the control unit.

Extreme atmospheric conditionsMasterpact devices have successfully passed the tests defined by the followingstandards for extreme atmospheric conditions:c IEC 68-2-1: dry cold at -55° C;c IEC 68-2-2: dry heat at +85° C;c IEC 68-2-30: damp heat (temperature +55° C, relative humidity 95%);c IEC 68-2-52 level 2: salt mist.Masterpact devices can operate in the industrial environments defined by standardIEC 947 (pollution degree up to 4).It is nonetheless advised to check that the devices are installed in suitably cooledswitchboards without excessive dust.

VibrationsMasterpact devices are guaranteed against electromagnetic or mechanicalvibrations.Tests are carried out in compliance with standard IEC 68-2-6 for the levels requiredby merchant-marine inspection organisations (Veritas, Lloyd’s, etc.):c 2 to 13.2 Hz: amplitude ±1 mm;c 13.2 to 100 Hz: constant acceleration 0.7 g.Excessive vibration may cause tripping, breaks in connections or damage tomechanical parts.

Electromagnetic disturbancesMasterpact devices are protected against:c overvoltages caused by devices that generate electromagnetic disturbances;c overvoltages caused by atmospheric disturbances or by a distribution-systemoutage (e.g. failure of a lighting system);c devices emitting radio waves (radios, walkie-talkies, radar, etc.);c electrostatic discharges produced by users.Masterpact devices have successfully passed the electromagnetic-compatibilitytests (EMC) defined by the following international standards:c IEC 60947-2, appendix F;c IEC 60947-2, appendix B (trip units with earth-leakage function).The above tests guarantee that:c no nuisance tripping occurs;c tripping times are respected.



Possible positions

Power supplyMasterpact devices can be supplied either from the top or from the bottom withoutreduction in performance, in order to facilitate connection when installed in aswitchboard.

Installation in switchboard

Mounting the circuit-breakerIt is important to distribute the weight of the device uniformily over a rigid mountingsurface such as rails or a base plate.This mounting plane should be perfectly flat (tolerance on support flatness: 2 mm).This eliminates any risk of deformation which could interfere with correct operationof the circuit breaker.Masterpact devices can also be mounted on a vertical plane using the specialbrackets.

Catch not supplied

Door interlock catch

Mounted on the right or left-hand side of the craddle,this device inhibits opening of the cubicle door whenthe circuit breaker is in «connected» or «test»position. It the breaker is put in the «connected»position with the door open, the door may be closedwithout having to disconnect the circuit breaker.


Cable-type door interlockConnection of MN, MX and XFvoltage releases

NT/NWCable-type door interlockThis option prevents door opening when the circuit breaker is closed and preventscircuit breaker closing when the door is open.For this, a special plate associated with a lock and a cable is mounted on the rightside of the circuit breaker.With this interlock installed, the source changeover function cannot beimplemented.

Wiring of voltage releasesDuring pick-up, the power consumed is approximately 150 to 200 VA. For lowcontrol voltages (12, 24, 48 V), maximum cable lengths are imposed by the voltageand the cross-sectional area of cables.Recommanded maximum cable lengths (meter)

Power connection

Busbars connectionsThe busbars should be suitably adjusted to ensurethat the connection points are positioned on theterminals before the bolts are inserted BThe connections are held by the support which issolidly fixed to the framework of the switchboard, suchthat the circuit breaker terminals do not have tosupport its weight C. (This support should be placedclose to the terminals).

Cables connectionsIf cables are used for the power connections, makesure that they do not apply excessive mechanicalforces to the circuit breaker terminals.For this, make the connections as follows:c extend the circuit breaker terminals using short barsdesigned and installed according to therecommendations for bar-type power connections:v for a single cable, use solution B oppositev for multiple cables, use solution C opposite.c in all cases, follow the general rules for connectionsto busbars:v position the cable lugs before inserting the boltsv the cables should firmly secured to the framework ofthe switchboard.

ClampingCorrect clamping of busbars depends amongst other things, on the tighteningtorques used for the nuts and bolts. Over-tightening may have the sameconsequences as under-tightening.For connecting busbars (Cu ETP-NFA51-100) to the circuit breaker, the tighteningtorques to be used are shown in the table below.These values are for use with copper busbars and steel nuts and bolts, class 8.8.The same torques can be used with AGS-T52 quality aluminium bars (Frenchstandard NFA 02-104 or American National Standard H-35-1).

Temperature derating

Temperature deratingThe table below indicates the maximum current rating,for each connection type, as a function of the ambienttemperature around the circuit breaker and thebusbars.Circuit breakers with mixed connections have thesame derating as horizontally connected breakers.For ambient temperatures greater than 60 °C,consult us.Ti: temperature around the circuit breaker and itsconnection

Power dissipation and input / outputresistanceTotal power dissipation is the value measured at IN,50/60 Hz, for a 3 pole or 4 pole breaker (values abovethe power P = 3RI2).The resistance between input / output is the valuemeasured per pole (cold state).

Factors affecting switchboard designThe temperature around the circuit breaker and itsconnections:This is used to define the type of circuit breaker to beused and its connection arrangement.Vents at the top and bottom of the cubicles:Vents considerably reduce the temperature inside theswitchboard, but must be designed so as to respectthe degree of protection provided by the enclosure.For weatherproof heavy-duty cubicles, a forcedventilation system may be required.The heat dissipated by the devices installed in theswitchboard:This is the heat dissipated by the circuit breakersunder normal conditions (service current).The size of the enclosure:This determines the volume for cooling calculations.Switchboard installation mode:Free-standing, against a wall, etc.Horizontal partitions:Partitions can obstruct air circulation within theenclosure.

Fixing points are identical for Masterpact (M08 to M32) and Masterpact (NW08 to NW32),except for the four-pole craddle.

It is possible to replace a Masterpact (M08 to M32) with a new Masterpact (NW08to NW32) with the same power rating.Substitution is possible for the following types of circuit breakers:c N1, H1, H2 for both fixed and drawout versionsc L1 for drawout versions up to 2000 A.
