The IMO UB10D3003A is a compact 3-pole miniature circuit breaker (MCB) designed to protect three-phase electrical circuits against overloads and short circuits. Part of the IMO UB10 circuit protection range, it is suitable for industrial control panels, machinery, automation equipment and commercial distribution systems requiring reliable low-current circuit protection.
Featuring a D curve tripping characteristic, the UB10D3003A can tolerate the temporary inrush currents generated by transformers, motors, solenoids and other inductive equipment. This helps reduce nuisance tripping during normal start-up while maintaining dependable disconnection during sustained overload or short-circuit conditions.
With a rated current of 3 A, a 3-pole configuration and a 10 kA breaking capacity, the UB10D3003A provides simultaneous protection and isolation across three conductors. Its DIN rail-mounted construction supports straightforward integration into distribution boards, switchboards and industrial control enclosures.
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected, helping protect conductors, components and connected equipment from damage. Thermal protection responds to sustained overload conditions, while magnetic protection provides rapid disconnection during short-circuit faults.
The D curve characteristic of the IMO UB10D3003A allows higher temporary inrush currents than more sensitive trip curves. This makes it suitable for inductive equipment such as control transformers, motors, contactor coils and solenoids that may draw a significant current surge when energised.

It is used to protect low-current three-phase electrical circuits against overloads and short circuits, particularly where inductive equipment generates temporary starting currents.
The miniature circuit breaker has a rated current of 3 A.
A D curve circuit breaker tolerates relatively high temporary inrush currents before tripping, making it suitable for transformers, motors, solenoids and other inductive equipment.
The UB10D3003A has a 3-pole configuration, allowing three conductors or phases to be protected and isolated simultaneously.
It is designed for installation on a standard 35 mm DIN rail inside a suitable distribution board, switchboard or electrical control panel.
