Rated 4.3 out of 5 stars.
Need to add a signal contact to your ABB circuit breaker? This is the MCB-10 auxiliary contact block. It's a 1 Normally Open (1NO) unit, brand new from ABB in its original packaging. This little module snaps onto compatible ABB miniature circuit breakers (MCBs) to give you an electrical signal when the breaker trips or is on. Super useful for control panels, alarm systems, or remote monitoring. If you're an electrician, panel builder, or doing industrial maintenance, having these on hand is a must for customizing your protection setups. Simple to install, just make sure it's compatible with your specific ABB breaker model. A small part with a big job!
