          Application

          The item is in comply with standard of IEC61008-1, applying to the circuit of AC 50/60Hz, 230V single phase, 400V  three phases or b
          elow it for industrial and mining enterprise, trade building, commerce and family. It is mainly used  for preventing electric fire and personal
          casual accident caused by personal electric shock or leakage of electrified wire net, this is a current operated, fast leakage protector of pure
          electromagnetic type, which can break off fault circuit rapidly in order to avoid occurrence of accident.
          The item is precise in structure , less elements,  without auxiliiary power and high working  reliabiility.
          The function of the switch wonl't be influenced by ambient temperature  and lightning. The mutual inductor of the  item is used to test vector
          differential value of passing current, and produces a relevant output power and add it to the tripper in secondary winding, if the current of
          vector differential value of protected circuit of personal electric shock is up to or oveir leakage operating current, the tripper will act and cut off
          so that the item will take effect of protection.
