RCCB YUANKY new arrival N7R series RCCB 63A 80A 100A 500ma residual current circuit breaker
N7R
RESIDUAL CURRENT CIRCUIT BREAKER
General
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 below 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 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 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 so that the item will take effect of protection.
