Residual Current Circuit Breaker (RCCB)

The RCCB is in conformity with the standard of IEC61008. The RCCB can cut off the fault circuit immediately on the occasion of shock hazard of earth leakage of trunk line. Thus, it is suitable to avoid the shock hazard and fire caused by earth leakage. The RCCB is mainly suitable for useing in varieties of plants and enterprises, buildings constructions. It can be used in circuits up to 1 phase 230V and 3 phase 400V 50/60Hz. RCCB is not suitable for use on DC pulse system.
