The IMO UB10D1004A is a dependable UL489 miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection for industrial control systems, machinery and electrical installations. As part of the trusted IMO UB10 series, this single-pole circuit breaker delivers effective branch circuit protection for low-current industrial applications.
Featuring a D curve tripping characteristic, the UB10D1004A is ideally suited to circuits supplying transformers, power supplies, solenoids, contactors and other inductive equipment that generate high inrush currents during energisation. Its thermo-magnetic operating mechanism provides rapid fault isolation while helping to minimise nuisance tripping during normal operation.
With a 4 A rated current, a single-pole configuration and a 10 kA short-circuit breaking capacity, the IMO UB10D1004A is ideal for protecting sensitive control circuits. Its compact DIN rail mounted design enables quick installation inside industrial control panels, machinery cabinets and electrical enclosures.
Miniature circuit breakers automatically disconnect electrical circuits when overload or short-circuit conditions occur, protecting wiring, industrial equipment and sensitive control components from damage. This improves operational safety, reduces downtime and enhances overall system reliability.
The IMO UB10D1004A is particularly suited to industrial automation systems, OEM machinery and electrical control panels where dependable low-current branch circuit protection is essential. Its D curve characteristic allows temporary inrush currents without unnecessary tripping when protecting inductive loads.
