Application
KEZ9-63 residual current circuit breaker can cut off the fault circuit immediately on the occasion of shock hazard or earth leakage of trunkline. Thus it is suitable to avoid the shock hazard and fire caused by earth leakage. It can be used in circuits up to 2 poles 230V, 4poles 400V, 50 or 60Hz. It is in conformity with the standards of IEC61008.1
