Why Choose the IMO B10D2004A Miniature Circuit Breaker?
The IMO B10D2004A is a compact and reliable miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the IMO B10 circuit protection range, it provides dependable performance for industrial control panels, commercial distribution boards and machinery applications.
This circuit breaker features a D curve tripping characteristic, making it suitable for circuits with high inrush currents such as transformers, solenoids, motor control circuits and other inductive loads. Its 2 pole configuration enables simultaneous switching and protection across two conductors for improved circuit isolation.
With a rated current of 4 A and a 10 kA short-circuit breaking capacity, the B10D2004A is ideal for low-current circuits that require robust fault protection and reliable DIN rail mounted installation.

Reliable Protection for High Inrush Circuits
Miniature circuit breakers such as the IMO B10D2004A automatically disconnect a circuit when excessive current is detected. This helps protect cables, equipment and connected loads from damage caused by overloads or short-circuit faults.
The D curve response is designed for circuits where high starting currents may occur during normal operation. This makes the B10D2004A particularly suitable for transformer circuits, motor control equipment, solenoids and other inductive loads that require reliable protection without nuisance tripping.
Typical Applications
- Industrial control panels and automation cabinets.
- Transformer and inductive load circuits.
- Motor control and machinery protection.
- Commercial electrical distribution boards.
- Solenoid and coil circuits.
- Low-current circuits requiring high breaking capacity protection.
