Why Choose the IMO UB10D2001A Miniature Circuit Breaker?
The IMO UB10D2001A is an industrial UL 489 miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Manufactured by IMO Precision Controls, this two-pole circuit breaker uses thermo-magnetic protection to safeguard wiring, machinery, automation equipment and electrical control systems.
As part of the established IMO UB10 miniature circuit breaker series, the UB10D2001A features a D curve tripping characteristic. Its instantaneous magnetic trip range of approximately 10 to 20 times the rated current makes it suitable for circuits containing transformers, motors, solenoids and other inductive loads that can produce high starting currents.
With a rated operational current of 1 A, a two-pole configuration and a 10 kA short-circuit breaking capacity, the UB10D2001A provides dependable branch circuit protection in a compact DIN rail format. It is well suited to industrial control panels, machine-building applications and OEM automation systems.

Reliable Protection for Industrial Electrical Systems
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected. The thermal mechanism responds to sustained overload conditions, while the magnetic mechanism provides rapid interruption during severe short circuits, helping to protect conductors, machinery and connected equipment.
The D curve characteristic of the IMO UB10D2001A accommodates temporary current surges generated when inductive equipment is 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.
