Description:
Residual current circuit-breaker is applicable to the circuits under the following conditions: fixed AC voltage:50/60HZ, rated current:63A,1P+N 230V or 3P+N 400V.The residual current circuit-breaker can protect the safety of people and equipments, in the event that one gets an electric shock or the electric leakages excesses a set amount, by cutting off the fault power within a very short time. Besides, the residual current circuit-breaker can also be used to prevent the circuit and the motor from overloading and be used for infrequent line conversion and infrequent starting of motor as well.
