HQR4
 

HQR4(F360)(electronic & electromagnetic) RCCB are applying to the circuit of Ac50/60Hz,230V single phase, 400V three phases and adapted for industrial mining enterprise, trade building, commerce and family. Mainly prevent electric fire and personal casualty 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. It is precise in 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 elecric 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.
