Cjl1-125-B 100A 4p RCCB ELCB MCB Residual Current Circuit Breaker

Short Description:

  • Cambered cover and handle make the operation be more comfortable and appearance be more beautiful.
  • The indication window of contact position.
  • Transparent clamshell with label.
  • Protect the circuit under the condition of overload, and the handle is tripped and stopped at the middle position, so as to repair the circuit with fault     quickly. The handle cannot be stopped at the position during manual operation.
  • lt has earthing fault, electric leakage and isolation and protection function.
  • High short circuit current tolerance.
  • It has earthing fault, electric leakage and isolation and protection function.
  • It is equipped with finger-protection wiring terminal.
  • The shell and components are made of high flame resisting, high temperature resisting and impact resisting engineering plastic.
  • lf the current of earthing fault or electric leakage exceeds the stipulated value, the circuit will be cut off automatically.
  • The dynamic and wire pressure are independent and are not affected by external disturbance and voltage fluctuation.

Tripping scope as per smooth DC residual current (type B shall meet following requirements on the premise of type A)

  • For sinusoidal AC residual current no more than 1000Hz, the trip current range between diferent frequencies according to the requirements of Table 2.With a sudden residual trip current in Table 2, the breaking time should be no more than 0.3s,The minimum no trip time of type S should be no less than 0.13s, and the maximum breaking time should not exceed 0.5s.
  • lf smooth residual current 0.4 time rated residual operation current (I△n) or 10 mA smooth DC residual current (the bigger shall prevail) is overlapoed on the rated frequency AC residual current. type B RCCB shall be operated. and the AC trippind current shall be no more than l△n.
  • If smooth DC residua current 0.4 tme rated residual operation current (I△n) or 10 mA smooth DC residua current (the biocer shaprevai) is overlapped on the pulse DC residual current. type B RCCB shall be operated. The tripping current of RCCB with l△n > 0.01A shall be no more than 1.4 l△n while the tripping current of RCCB with l△n≤0.01 A shall be no more than 2l△n.
  • For the pulse DC residual current which is stably increased and produced by two relative rectifying circuits, type B RCCB shall be actuated within the scope of 0.5 l△n to 22 1△n Type B shall trip within the time range specified according to the Table 1,With a sudden pulsating DC residual current applied to the rectifier circuit.
  • For the pulse DC residual current which is stably increased and produced by three relative rectifying circuits, type B RCCB shall be operated within the scope of 0.5 l△n to 22 1△n Type B shall trip within the time range specifed according to the Table 1,With a sudden pulsating DC residual current applied to the rectifier circuit.
