Circuit Breaker>>Earthlake Circuit Breaker>>DZL4 RCD/RCCB



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.
