DZ47L, C45L Earth Leakage Circuit Breaker is used for the protection against electrical leakage in the circuit of 50Hz or 60Hz, rated voltage single-phase 240V, 3 phase 415V, rated current up to 60A. When somebody gets an electric shock or the residual current of the circuit exceeds the fixed value, the ELCB can cut off the power within the time of 0.1 seconds automatically to protect the personal safety andpreventing the equipment from the fault resuted by the residual current. With thisfunction, the ELCB can protedt the circuit against overload and short circuit or can beused for the unfrequent switch over of the circuit under normal conditions, it conformsto IEC898-87 & IEC755.
