ASJ series residual current action relays can be combined with low-voltage circuit breakers or low-voltage contactors to form a combined residual current protection device, which is mainly suitable for AC 50Hz, rated voltage 400V and below TT and TN system power distribution lines used to perform electrical circuits Ground fault protection can prevent equipment damage and electrical fire accidents caused by ground fault currents, and can also be used to provide indirect contact protection against personal electric shock hazards.
