OVERVIEW
CIDAC373 Series
Two-Pole RCBO for Single-Phase Ac Systems
The CIDAC373 Series is a compact residual current circuit breaker with overcurrent protection (RCBO), designed to protect railway and industrial electrical systems against overloads, short circuits and residual current faults. Combining an Airpax IAL circuit breaker with a current imbalance detector, it provides protection for critical electrical circuits.
Designed for single-phase AC applications, the CIDAC373 offers current ratings up to 50 A, multiple trip delay options and auxiliary contact outputs. Its compact, panel-mounted design supports integration into railway vehicle electrical systems and industrial installations.
