Why Choose the IMO UB10D2020A Miniature Circuit Breaker?
The IMO UB10D2020A is a compact and dependable 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions. Part of the IMO B10 circuit protection range, it is suitable for use in industrial machinery, commercial distribution systems, OEM equipment and electrical control panels.
Featuring a D curve tripping characteristic, the UB10D2020A is designed for circuits that experience high temporary starting currents. This makes it particularly suitable for motors, transformers, solenoids and other inductive equipment that could cause nuisance tripping when protected by a more sensitive breaker characteristic.
With a rated current of 20 A, a 2-pole configuration and a short-circuit breaking capacity of up to 10 kA, the UB10D2020A provides effective circuit protection and simultaneous isolation of two conductors. Its compact DIN rail-mounted construction enables straightforward installation inside distribution boards, switchboards and industrial control cabinets.

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 when a short-circuit fault occurs.
The D curve characteristic of the IMO UB10D2020A permits higher temporary inrush currents than typical B curve or C curve breakers. This makes it suitable for protecting motors, transformers and industrial machinery while helping to prevent 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.
