NB-DPNL Earth Leakage Circuit Breaker

NB-DPNL earth leakage circuit breaker is used for the protection, against electrical leakage in the circuit of 50Hz or 60Hz, rated voltage single-phase 230V, three-phase 400V, rated current up to 60A. When somebody gets an electric shock or the residual current of circuit exceeds the fixed value, the ELCB can cut off the power within the time of 0.1s automatically protecting the personal safety and preventing the equipment from the fault resulted from the residual current. With this function, the ELCB can protect the circuit against overload and short circuit or can be used for the unfrequent switchover of the circuit under normal conditions. It conforms to IEC 898 &IEC 755.
