Why Choose the IMO UB10D1005A Miniature Circuit Breaker?
The IMO UB10D1005A is a compact UL 489 miniature circuit breaker (MCB) designed to protect industrial control circuits, machinery and electrical equipment against overloads and short circuits. As part of the established IMO UB10 series, this single-pole device provides dependable branch circuit protection for low-current industrial applications.
Featuring a D curve tripping characteristic, the UB10D1005A is suitable for circuits supplying transformers, power supplies, solenoids, contactors and other inductive equipment that can produce high temporary inrush currents. Its thermal-magnetic operating mechanism provides reliable fault disconnection while helping to reduce nuisance tripping during normal equipment energisation.
With a 5 A rated current, a single-pole configuration and a 10 kA short-circuit breaking capacity, the IMO UB10D1005A is well suited to control, auxiliary and equipment supply circuits. Its compact DIN rail mounted construction supports straightforward installation inside industrial control panels, machinery cabinets and electrical enclosures.

Reliable Protection for High-Inrush Control Circuits
Miniature circuit breakers automatically disconnect electrical circuits when overload or short-circuit conditions occur. This helps protect cables, control components and connected equipment from electrical damage while improving installation safety, reducing downtime and simplifying circuit restoration after a fault has been corrected.
The D curve response of the IMO UB10D1005A allows correctly designed circuits to tolerate brief start-up currents significantly above the normal operating current. This makes the breaker particularly suitable for inductive equipment and other devices that experience substantial current surges during energisation.
Typical Applications
- Industrial control and auxiliary circuits.
- Control transformers and industrial power supplies.
- Solenoid, relay and contactor circuits.
- PLC and factory automation panels.
- OEM machinery and production equipment.
- Electrical cabinets and distribution enclosures.
