The IMO UB10C3040A is a high-performance UL489 miniature circuit breaker (MCB) engineered to provide dependable overload and short circuit protection for industrial control panels, OEM machinery and commercial electrical installations. As part of the trusted IMO UB10 series, this three-pole circuit breaker delivers reliable protection for demanding three-phase applications.
Designed with a C curve tripping characteristic, the UB10C3040A is well suited to protecting circuits supplying motors, transformers, contactors and other inductive loads with moderate inrush currents. Its thermal-magnetic operating mechanism delivers fast fault isolation while reducing nuisance tripping during normal equipment start-up.
With a rated current of 40 A, a three-pole configuration and a 10 kA short-circuit breaking capacity, the IMO UB10C3040A provides dependable branch circuit protection. Its compact DIN rail mounted design allows quick installation within industrial control panels and electrical distribution systems.
Miniature circuit breakers automatically disconnect electrical circuits during overload and short circuit conditions, helping to protect wiring, machinery and connected equipment from damage. This improves operational safety, minimises downtime and enhances the reliability of industrial electrical systems.
The IMO UB10C3040A is widely used in industrial machinery, automation systems and OEM equipment where reliable three-phase circuit protection, consistent switching performance and compliance with recognised standards are essential.
