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 50/60Hz, 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.
