RCCB ID Earth Leakage Breakers Function This EBS2L Residual current circuit breaker is in conformity with the withstand of IEC 61008. The RCCB can cut off the fault circuit immediately on the occasion of shock hazard or earth leakage of trunk. It is suitable to avoid the shock hazard and fire caused by earth leakage. The RCCB is mainly suitable for use in varieties of plants and enterprises, building construction 1 phase 230V and 3 phase 400V 50/60Hz. RCCB is not suitable for use on DC pulse system.
