Why Choose the IMO UB10D2015A Miniature Circuit Breaker?
The IMO UB10D2015A is a compact and reliable 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit faults. Part of the IMO B10 circuit protection range, it is suitable for industrial machinery, commercial distribution systems, OEM equipment and electrical control panels.
The breaker features a D curve tripping characteristic, enabling it to tolerate the temporary high starting currents commonly produced by motors, transformers, solenoids and other inductive equipment. This helps minimise nuisance tripping during normal start-up while maintaining effective protection against genuine overcurrent conditions.
With a rated current of 15 A, a 2-pole configuration and a short-circuit breaking capacity of up to 10 kA, the UB10D2015A provides dependable circuit protection and simultaneous isolation of two conductors. Its compact DIN rail-mounted format supports straightforward installation inside distribution boards and electrical enclosures.

Reliable Protection for High-Inrush Electrical Circuits
Miniature circuit breakers protect electrical wiring and connected equipment by automatically disconnecting the supply when excessive current is detected. Thermal protection responds to prolonged overload conditions, while magnetic protection provides rapid interruption during short-circuit faults.
The D curve characteristic of the IMO UB10D2015A permits higher temporary inrush currents than standard B curve or C curve breakers. This makes it particularly useful for protecting motors, transformers and inductive machinery without unnecessary tripping during normal equipment start-up.
Typical Applications
- Industrial motors and motor control circuits.
- Transformers and power supply equipment.
- Machinery and industrial automation systems.
- Commercial and industrial distribution boards.
- Solenoids, coils and other inductive loads.
- OEM control panels and electrical enclosures.
