Residual Current Circuit Breaker

The item is in accordance with standards of VDE 0664, CEE27 and BS4293 etc., applying
to the circuit of AC 50/60Hz, 240V single phase, 415V three phases and below
it for industrial and mining enterprise, building trade, commerce and family.
To mainly prevent electric fire and personal casuatly accident 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 accident. The item 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 lighting.The mutual inductor of the item is used to test vector differential
value of passing current, and produces are levant output power and add it 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.
