Detailed Product Description

A type RCCB:
BF62/BF64 is an usually used AC and DC circuit. This item is in accordance with standards of IEC, applying to the circuit of AC 50 / 60Hz, 240V single phase, 415V three phases and bellowing it for industrial and mining enterprise, trade building, commerce and family. 

To mainly prevent electric fire and personal casual-ty accidents caused by personal electric shock or leakage of electrified wire netting, this ELCB is a current-operated, fast leakage protector of pure electromagnetic type, which can break off fault circuit rapidly in order to avoid occurrence of accidents. This item is precise in structure, less elements, without auxiliary power and high working reliability. 

The function of this switch will not be influenced by ambient temperature and lighting. 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. 

Specifications:
1) Rated current: 6 - 100A
2) Rated leakage current: 30, 100, 300, 500mA
3) Pole: 2P, 4P
