The item is in accordance with the IEC, VDE, CEE, and BS standards. This circuit breaker with AC 50/60Hz, 240V single phase, 415V three phases and below is for industrial and mining purposes, large buildings, and commercial usage. To mainly prevent electric fire and personal accident caused by personal electric shock or leakage of electrified wire netting, this RCCB is a current-operated, fast leakage protector, and is purely electromagnetic, which can break off fault circuits rapidly in order to avoid accidents.
The item is precise, with fewer elements, without auxiliary power, of 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 values of passing currents, and to produce 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 over leakage operating current, the tripper will act and cut off for protection.
