Product Description


SRL5 - 63 series residual current action circuit breaker is suitable for AC 50Hz, rated voltage up to 400v, rated curent upto 63A in the line. When a person is electrocuted or the leakage current of the power grid exceeds the specifed value, the residual current operated circuit breaker can automatically cut off the power supply in a very short time to protect the safety of the person and prevent the equipment from accidents caused by leakage current.Residual curent action circuit breaker also has overload and short circuit protection function, can be used to protect the lineoverload and short circuit, can also be used as infrequent conversion of the line under normal circumstances.Applicable to industrial, commercial, high-rise and civil residential and other occasions.
