RDB9-63(MCB) 6KA/10KA

The RDB9-63 miniature circuit breaker is designed for residential wiring, commercial circuits and industrial power distribution systems. Compatible with AC 50/60Hz grids, it fits 1-pole (230V/240V) and 2/3-pole (400V) setups. It works as a switch for infrequent line switching, and automatically cuts power during overloads and short circuits to protect wiring and electrical devices, preventing equipment damage and electrical hazards.
