Technical informations

Selective residual current circuit-breakers are used in systems with stacked distribution boards. In case of a fault, the switch in whose system section the residual current is detected switches off. The selective RCCBs provide fire and fault protection (due to indirect contact), but no additional protection (direct contract, personnel protection).
