| The item is in accordance with standards of IEC1008,VDE 0664,CEE 27 and BS 4239 etc,applying to the circuit of AC 50/60Hz, 240V single phase, 415V three phases and below it for industrial and mining enterprise, trade building, commerce and family. To mainly prevent electric fire and personal casual accident caused by personal electric shock or leakage of electrified wire netting, this RCCB 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 precisein structure, less elements, without auxiliary power and high working reliability. The function of the switch won''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 arelevantoutput power and add it to the tripper in secondary winding, if the current of vectordifferentialvalue of protected circuit of personal electric shock is up to or over leakage operating current, the tripper will act and cut off so that the item will take effect of protection. | |||||||||
