Product overview:
CZM18L series residual current circuit breaker is applicable to AC 50Hz lines with rated voltage of 230/400V and rated current of 63A. When the human body gets an electric shock or the leakage current of the power grid exceeds the specified value, the residual current operated circuit breaker can quickly cut off the fault power supply in a very short time, protect the safety of people and electrical equipment, protect the overload or short circuit of the line, and it can also be used for infrequent operation and conversion of the line under normal conditions. The product is suitable for industrial, commercial, high-rise buildings and civil residential and other occasions.
