HKKM1L residual current operated circuit breaker series

It is protects the human being from indirect contact,also protects from any potential fire hazard cause by long existing ground fault which can not be detected by over-current protector
When other protective devices are out of order, this residual current circuit breaker whose rated residual operated current is 30mA will play a role of additional protector directly
