● The measurement of AC type after-current; ● The streamer display of current percentage; ● The setting of rated residual action current; ● The setting of non-driving time of limitation; ● Two-pair relay output; ● Possessing the function of on-the-spot and long-distance testing and resetting.
ASJ Series of action relay of after-current, low-voltage circuit break or low-voltage contactor can be made up for combined after-current production device, which is mainly applied for the TT and TN system distributing circuit with the alternating current 50Hz, the rated voltage 400V or below.
ASJ Series of action relay of after-current is applied in the earth fault protection for the electric circuit, so as to prevent the equipment damage and the fire accident of electric equipment caused by the ground fault current, moreover, it also can provide indirect contact protection against the electric shock risk.
