M8l Series 3p AC 60Hz 440V 630A MCCB Moulded Case Circuit Breaker

Summary

      Dvigi current-leakage module can be connected with NS100-630 circuit breaker to form the earth leakage circuit breaker. After connection, the circuit breaker has not only overload protection and short circuit protection functions, but also current leakage and grounding fault protection functions. It mainly used for the civil constructions and industrial distribution places to continuously observe the insulation condition of power equipment to prevent from fire and electric shock dangers caused by current leakage or grounding fault.
      Dvigi current-leakage module is applied with rated voltage up to 440V, rated current up to 630A, AC 50Hz or 60Hz, with the grounding type of TT, TN-S and TN-C-S grounding system's distribution network.
      Dvigi current-leakage module is vertically installed below the NS circuit breaker.
      It can directly operate the circuit break through its inner operation structure, which is convenient and easy for installation.
 

Main characteristics

 IEC60947-2 standard
 Minimum ambient temperature to -25C
 The installation of Dvigi with NS circuit breaker doesn't change the circuit breaker's original performance.
 The module doesn't need additional operation power and can be connected directly with electric power.  Supplied by 3-phase electric power, it can still work normally even lack 1 phase voltage.
Spot adjustable: Wide range of modulation of rated residual action current In. (5 steps). It can be used for industrial and civil  construction areas. Residual current delay action time is adjustable (4 steps) so as to ensure the match with under grade current leakage protection action time and continuity of power supply. The users can do the adjustment according to the practical situation of circuit.
 Wide operating voltage: when the phase voltage falls to 80V, the module can still work normally and its maximum operating voltage can be up to 440V.
Current leakage alarming indicating function: SDV auxiliary switch (additional attached) can be installed inside the module. When the circuit breaker trips caused by the circuit current leakage or grounding fault, it can indicate or alarm in a long-distance.
 Strong Anti-jamming: Its anti-jamming function accords with IEC 255 and IEC801-2 to -5's norms, which has the anti-jamming functions such as protections of instant over voltage, lighting strike, over voltage, static discharging, wireless blanketing of  structure closing operation. It is also not affected by DC distributary. (IEC947-2 appendix B, A series equipment)
