DZ47NL 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 electirc shock or the residual current of the circuit exceeds the fixed value,the ELCB can cut off the power within the time of 0.1s automatically protecting the personal safely and preventing the equipement from the fault resuted from teh residual current.With this function, the ELCB can protect the circuit against overload and short circuit or can be used for the unfrequent switch over of the circuit under normal conditions,It conforms to IEC60898&IEC60755.
