Why Choose the IMO UB10D1030A Miniature Circuit Breaker?
The IMO UB10D1030A is a high-performance UL 489 miniature circuit breaker (MCB) designed to protect industrial electrical installations against overloads and short circuits. Manufactured by IMO Precision Controls, this single-pole circuit breaker provides dependable thermo-magnetic overcurrent protection for machinery, automation systems and electrical control panels.
As part of the established IMO UB10 miniature circuit breaker series, the UB10D1030A features a D curve tripping characteristic. Its instantaneous tripping range of approximately 10 to 20 times the rated current makes it particularly suitable for circuits containing motors, transformers, solenoids and other loads with high starting currents.
With a rated operational current of 30 A, a 10 kA short-circuit breaking capacity and a compact DIN rail mounting format, the UB10D1030A offers reliable branch circuit protection while supporting efficient installation inside industrial electrical enclosures and machinery cabinets.

Reliable Protection for Industrial Electrical Systems
Miniature circuit breakers automatically disconnect an electrical circuit when excessive current is detected. Thermo-magnetic operation combines thermal protection against sustained overloads with rapid magnetic tripping during severe short-circuit conditions, helping protect cables, equipment and electrical installations.
The D curve characteristic of the IMO UB10D1030A accommodates the temporary current surges produced when motors, transformers and other inductive equipment are energised. This helps minimise nuisance tripping while maintaining reliable protection against genuine electrical faults.
Typical Applications
- Industrial control panels and electrical cabinets.
- Electric motor and machinery circuits.
- Transformers, solenoids and inductive loads.
- OEM automation equipment.
- Manufacturing and production machinery.
- Industrial branch circuit protection.
