Why Choose the IMO UB10D1020A Miniature Circuit Breaker?
The IMO UB10D1020A is an industrial miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit faults. Manufactured by IMO Precision Controls, it provides dependable thermo-magnetic protection for machinery, automation equipment, control panels and OEM electrical systems.
As part of the IMO UB10 circuit breaker series, the UB10D1020A features a D curve tripping characteristic. This operating curve is suitable for circuits containing equipment with high start-up or inrush currents, including electric motors, transformers, solenoids and other inductive loads.
With a rated current of 20 A, a single-pole configuration and a 10 kA short-circuit breaking capacity, the UB10D1020A offers robust branch circuit protection for demanding industrial applications. Its compact DIN rail mounting format also supports efficient installation inside electrical cabinets and distribution assemblies.

Reliable Protection for Industrial Electrical Systems
Miniature circuit breakers automatically interrupt the electrical supply when an overload or short circuit is detected. Their thermal mechanism responds to sustained excess current, while the magnetic mechanism provides rapid disconnection during severe short-circuit conditions.
The D curve characteristic of the IMO UB10D1020A accommodates the temporary current surges generated when motors, transformers and other inductive equipment are energised. This helps reduce nuisance tripping while maintaining dependable protection for cables, equipment and electrical installations.
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.
