DZ47L ,C45L earth leakage circuit breaker is used for the protection ,against electrical leakage in the circuit of 50Hz or 60 Hz ,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 equipment from the fault resulted by the residual current overload and short circuit or can be used for the infrequent switchover of the circuit under the normal conditions. It conforms to IEC1009 standard
