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.

Reliable Status Monitoring for Circuit Protection Devices
The IMO B10-F3 allows the status of a compatible miniature circuit breaker to be monitored by an external signalling or control circuit. This enables operators, control systems or panel indicators to identify whether the associated breaker is open or closed.
Its changeover contact design makes the accessory suitable for a wide range of indication and monitoring requirements, including alarm circuits, PLC inputs, building management systems and electrical panel status feedback.
Typical Applications
- Electrical control panels.
- Distribution boards.
- Remote MCB status indication.
- PLC and automation signalling circuits.
- Alarm and monitoring systems.
- Commercial and industrial electrical installations.
