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. Thus it is suitable toavoid 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 notsuitable for use on DC pulse system.
