Reliable Protection for Low-Current Three-Phase Circuits
Miniature circuit breakers automatically disconnect electrical circuits when overload or short circuit conditions occur. This helps protect cabling, equipment and electrical systems while improving safety and reducing the risk of downtime caused by electrical faults.
The IMO B10 series is designed for applications requiring a higher short circuit breaking capacity. The D curve characteristic makes the B10D3004A suitable for circuits where high starting currents may occur, while the 4A rating supports accurate protection of smaller three-phase equipment and control circuits.
Typical Applications
- Three-phase control circuits.
- Industrial automation panels.
- Specialist machinery and OEM equipment.
- Transformer and inductive load protection.
- Commercial distribution boards.
- Switchboards and electrical control systems.
