Description of Residual Current circuit breaker
ID 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
Features of earth leakage circuit breaker
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

OPERATION PRINCIPLE FIG.
30mA 100mA 300mA Rccb Circuit Breaker,Differential Circuit Breaker
A human being is able to sustain an electric shock to the extent of 30 mA. While upto 10 mA may just evoke a prickling sensation, 10 mA onwards may lead to muscular contraction, further leading to a respiratory paralysis at around 30mA. RCCBs are therefore designed to look for small changes in residual current. In cases where protection from fire is sought, RCCBs are also used to track higher changes in residual current of up to 300mA.
