NM8L, NM8SL series residual current operated circuit breaker
Residual current operated circuit breaker
The NM8 or NM8S plastic case circuit breakers are conveniently assembled with the residual current protection module to provide the NM8L and NM8SL residual current operated circuit breakers. The NM8L and NM8SL series residual current operated circuit breakers are mainly suitable for circuits with AC 50Hz, rated voltage up to 400V and rated current up to 630A. Its main function is to provide indirect contact protection for personal shocks that are fatal, and to prevent electrical fires caused by ground fault currents. It can also be used to protect the line from overload, short circuit and under voltage, and can also be used as infrequent conversion of the line. Meet the standard: GB/T 14048.2, IEC 60947-2.
