YCB3 Circuit Breaker


Application Technical Data
YCB3(DPN) is applicable to protect line-conductor against overload, and short circuit of small sealed motors. It is main for protection of circuits with AC 220V and 50Hz/60Hz, and for unfrequent conversion under normal conditions as well. Its action can be up to two poles with its only one pole volume and be used as a leakage breaker by assembling with leakage.
It is produced as IEC60898.
