Why Choose the IMO UB10D2005A Miniature Circuit Breaker?
The IMO UB10D2005A is an industrial UL 489 miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection for machinery, automation equipment and electrical control panels. Manufactured by IMO Precision Controls, this two-pole circuit breaker uses thermo-magnetic protection to safeguard conductors and connected equipment against excessive current.
As part of the established IMO UB10 miniature circuit breaker series, the UB10D2005A features a D curve tripping characteristic. Its instantaneous magnetic trip range of approximately 10 to 20 times the rated current makes it suitable for motors, transformers, solenoids and other inductive loads that can generate high starting currents.
With a rated operational current of 5 A, a two-pole configuration and a 10 kA short-circuit breaking capacity, the UB10D2005A delivers reliable industrial branch circuit protection in a compact DIN rail format. It is well suited to machine-building applications, OEM automation systems and electrical distribution assemblies.

Reliable Protection for Industrial Electrical Systems
Miniature circuit breakers automatically disconnect electrical circuits when overloads or short circuits occur. Their thermal mechanism responds to sustained excess current, while the magnetic mechanism provides rapid interruption during severe fault conditions, helping to protect wiring, machinery and connected electrical equipment.
The D curve characteristic of the IMO UB10D2005A accommodates temporary current surges generated when motors, transformers and other inductive equipment are energised. This helps reduce nuisance tripping during normal start-up while maintaining dependable protection against genuine electrical faults.
Typical Applications
- Industrial control panels and electrical cabinets.
- Transformers, solenoids and inductive loads.
- Motor control and machinery circuits.
- OEM automation equipment.
- Manufacturing and production machinery.
- Two-pole industrial branch circuit protection.
