1.Application
DZL4 RCCB is in conformity with the standard of IEC61008. The RCCB can cut off  the faultcircuit immediately on the occasion of shock hazard or earth leakage  of trunk. Thus, it is suitableto avoid the shock hazard and fire caused by  earth leakage.The RCCB is mainly suitable for use in varieties of plants and  enterprises, building construction1 phase 230V and 3 phase 400V 50/60Hz. RCCB  is not suitable for use on DC pulse system.
