- HKKM1L residual current operated circuit breaker series:
- It protects the human being from indirect contact, also protects from any potential fire hazard cause by long existing ground fault which cannot 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 lf additional protector directly
