Functionsand characteristicsRemote operation 0Remote ON / OFFPB100797-23PB100808-32Electric motor (MCH)The electric motor automatically charges and recharges the spring mechanism whenthe circuit breaker is closed. Instantaneous reclosing of the breaker is thus possiblefollowing opening. The spring-mechanism charging handle is used only as a backupif auxiliary power is absent.The electric motor (MCH) is equipped as standard with a limit switch contact (CH)that signals the "charged" position of the mechanism (springs charged).CharacteristicsPower supply V AC 50/60 Hz 48/60 - 100/130 - 200/240 - 277- 380/415 - 400/440 - 480V DC 24/30 - 48/60 - 100/125 - 200/250Operating threshold0.85 to 1.1 UnConsumption (VA or W) 180Motor overcurrent2 to 3 In for 0.1 sCharging timemaximum 3 s for Masterpact NTmaximum 4 s for Masterpact NWOperating frequencymaximum 3 cycles per minuteCH contact10 A at 240 VDB101179Electric motor (MCH) forMasterpact NT.Electric motor (MCH) forMasterpact NW.Voltage releases (XF and MX)Their supply can be maintained or automatically disconnected.Closing release (XF)The XF release remotely closes the circuit breaker if the spring mechanism ischarged.Opening release (MX)The MX release instantaneously opens the circuit breaker when energised. It locksthe circuit breaker in OFF position if the order is maintained (except for MX"communicating" releases).Note: whether the operating order is maintened or automatically disconnected (pulse-type), XFor MX "communicating" releases ("bus" solution with "COM" communication option) always havean impulse-type action (see diagram).Characteristics XF MXPower supply V AC 50/60 Hz 24 - 48 - 100/130 - 200/250 - 277 - 380/480V DC 12 - 24/30 - 48/60 - 100/130 - 200/250Operating threshold 0.85 to 1.1 Un 0.7 to 1.1 UnConsumption (VA or W) Hold: 4.5Pick-up: 200 (200 ms)Circuit-breaker response time at Un 55 ms ±10 (Masterpact NT) 50 ms ±1070 ms ±10 (NW y 4000A)80 ms ±10 (NW > 4000A)Hold: 4.5Pick-up: 200 (200 ms)PB100809-16PB100818-16XF and MX voltage releases."Ready to close" contacts (PF)."Ready to close" contact (PF)The "ready to close" position of the circuit breaker is indicated by a mechanical indicatorand a PF changeover contact. This signal indicates that all the following are valid:b the circuit breaker is in the OFF positionb the spring mechanism is chargedb a maintained opening order is not present:v MX energisedv fault tripv remote tripping (second MX or MN)v device not completely racked inv device locked in OFF positionv device interlocked with a second device.CharacteristicsNT/NWMaximum number 1Breaking capacity (A) StandardMinimum load: 100 mA/24 Vp.f.: 0.3V AC 240/380 5AC12/DC12480 5690 3V DC 24/48 3125 0.3250 0.15Low-levelMinimum load: 2 mA/15 V DCV AC 24/48 3240 3380 3V DC 24/48 3125 0.3250 0.1549
