MCBH5-00

The ABB MCBH5-00 is a compact, plug-in auxiliary contact block designed for attachment to ABB System Pro M compact® S200 and S280 series miniature circuit breakers (MCBs) and residual current circuit breakers (RCCBs). It serves as a remote, electrically isolated signaling device, providing a reliable indication of the main breaker’s status (ON/OFF or TRIPPED).
