Why Choose the IMO B10D2050A Miniature Circuit Breaker?
The IMO B10D2050A is a high performance two pole miniature circuit breaker (MCB) designed to protect electrical installations against overloads and short circuits. As part of the robust IMO B10 Series, this MCB provides dependable protection for commercial, industrial and control panel applications where reliable fault interruption is required.
Featuring a D curve tripping characteristic, the B10D2050A is suitable for circuits with high inrush currents, including motors, transformers, solenoids and industrial equipment. Its compact modular design makes it easy to install in distribution boards, switchgear assemblies and machinery control panels.
With a 50 A current rating, 10 kA short circuit breaking capacity and suitability for 230/400 V AC systems, the IMO B10D2050A delivers reliable circuit protection whilst supporting straightforward DIN rail installation in demanding electrical environments.

Reliable Protection for High Inrush Circuits
Miniature circuit breakers automatically disconnect the supply when overload or short circuit conditions occur, helping protect cables, equipment and connected devices from electrical damage. The IMO B10D2050A combines thermal and magnetic protection to provide effective circuit isolation in demanding installations.
The D curve characteristic is particularly useful where equipment may draw a high starting current during energisation. This makes the B10D2050A suitable for industrial machinery, motor circuits and transformer-fed loads where standard B or C curve devices may trip too readily.
Typical Applications
- Industrial control panels.
- Commercial distribution boards.
- Motor and transformer circuits.
- Machinery electrical systems.
- Automation and OEM equipment.
- High inrush power distribution applications.
