The IMO UB10D2040A is a robust 2-pole miniature circuit breaker (MCB) engineered to provide dependable protection against overloads and short circuits in industrial, commercial and OEM electrical installations. As part of the proven IMO UB10 circuit protection range, this D curve MCB is specifically designed for applications with high inrush currents, including motors, transformers and other inductive loads.
Its D curve tripping characteristic allows temporary starting currents to pass without nuisance tripping while maintaining rapid disconnection during genuine fault conditions. Manufactured to recognised international standards, the UB10D2040A offers reliable thermo-magnetic protection in a compact DIN rail-mounted format for straightforward installation in control panels and distribution boards.
With a rated current of 40 A, a 2-pole configuration and a 10 kA breaking capacity, the UB10D2040A is ideal for protecting industrial machinery, automation systems and commercial electrical installations where dependable circuit protection is essential.
Miniature circuit breakers automatically disconnect electrical circuits whenever overload or short-circuit conditions occur, helping protect wiring, machinery and connected equipment from electrical damage. The thermo-magnetic design combines thermal overload protection with rapid magnetic fault interruption for dependable circuit safety.
The IMO UB10 series is widely used in industrial automation, machinery and commercial electrical installations. Its D curve characteristic makes it especially suitable for applications where motors, transformers and other inductive equipment generate high temporary starting currents.
