APPLICATION
Residual current circuit breaker is suitable to the circuit of AC50/60Hz.rated voltage 230V for 2 poles and 400V for 4 poles, and rated current up to 63A.When people get the electric shock, or the leakage current of the electrical network exceeds the fixed value, this RCCB can cut off the fault current in short period to protect people safty and the equipments. It is applicable to industrial area, commercial area, tall building and civil house. It complies with standard IEC/EN 61008.1 and GB1696.1
FEATURE
1).Provides protection against electric shock, earth fault, leakage current;
2).Fire resistant plastic casing endures abnormal heating and strong impact;
3). Improved mechanical and bimetallic system provides more precise tripping
4).Equipped with finger protected in connection terminals;
5). Both terminal wiring and busbar wiring are available
6). Small size and weight, easy installation and wiring high and durable performance.
