Leakage protection circuit breakers are suitable for use as leakage protection in circuits with AC 50Hz, rated voltage of 230V/400V, and rated current up to 63A . When someone is electrocuted or the leakage current of the circuit exceeds the specified value, the residual current circuit breaker can automatically cut off the power supply within 0.1 seconds, ensuring personal safety and preventing accidents caused by leakage current of the equipment. Leakage circuit breakers have overload and short circuit protection functions, which can be used to protect the circuit from overload and short circuit, and can also be used for infrequent replacement of the circuit under normal circumstances.
This product complies with the GB16917.1 standard.
