Why Choose the IMO B10-F3 MCB Auxiliary Contact?

The IMO B10-F3 is a compact MCB auxiliary contact designed for use with compatible IMO B10 miniature circuit breakers. It provides a practical way to monitor the open or closed status of a protection device, supporting clear indication, remote signalling and integration into control panel circuits.

As an auxiliary switch accessory, the B10-F3 helps panel builders and electrical engineers improve visibility of circuit breaker status within industrial and commercial installations. Its slim modular design allows it to be fitted neatly alongside the associated MCB, helping maintain efficient use of DIN rail space.

With a 1 pole changeover contact, 6 A rating at 230 V AC / 24 V DC, 3 A rating at 400 V AC and a compact 9 mm width, the IMO B10-F3 is ideal for signalling applications in electrical panels, automation systems and distribution boards using compatible B10 C curve and D curve MCBs.
