DZ47LE-100 earth circuit breaker is used for the protection, against electrical leakage in the circuit of 50HZ or 60HZ, related voltage single -phase 240V, 2,3 and 4 phase 415V, rated current up to 100A. When somebody gets an electric shock or the residual current of circuit exceeds the fixed value, the ELCB can off the power within the time of 0.1s automatically to protect the personal safety and preventing the equipment form the fault resulted by the residual current. With this function, the ELCB can protect the circuit against switch over of the circuit under normal condition.
