DZ47L residual current circuit breaker is used for the protection against electrical leakage in the circuit of 50/ 60Hz and rated voltages 240V (single pole) or 240/415V and below (3-phase), rated current up to 60A. When somebody gets an electric shock or the residual current of the circuit exceeds the fixed value, the R.C.C.B. can cut off the power within the time of 0.1s. Automatically protecting personal safety and preventing the equipment that from the fault, resulted the residual current. With this function, the R.C.C.B. can protect the circuit against overload and short circuit or can be used for the infrequent switchover of the circuit under normal conditions.
