The IMO UB10D1008A is a compact UL 489 miniature circuit breaker (MCB) designed to protect industrial control circuits, machinery and electrical installations against overloads and short circuits. Part of the established IMO UB10 series, this single-pole circuit breaker provides dependable branch circuit protection for industrial and commercial electrical applications.
Featuring a D curve tripping characteristic, the UB10D1008A is suitable for circuits supplying transformers, industrial power supplies, solenoids, contactors and other inductive equipment that can produce substantial temporary inrush currents. Its thermo-magnetic operating mechanism provides reliable fault disconnection whilst helping to reduce nuisance tripping during normal equipment energisation.
With an 8 A rated operational current, a single-pole configuration and a 10 kA short-circuit breaking capacity, the IMO UB10D1008A 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.
Miniature circuit breakers automatically disconnect electrical circuits when overload or short-circuit conditions occur. This helps protect conductors, control components and connected equipment from electrical damage whilst supporting safer operation, reducing downtime and simplifying circuit restoration after a fault has been corrected.
The D curve response of the IMO UB10D1008A allows correctly designed circuits to tolerate brief start-up currents of approximately 10 to 20 times the breaker's rated current before instantaneous magnetic tripping occurs. This makes it particularly suitable for inductive loads and other equipment that experiences substantial current surges during energisation.

It is used to protect 8 A industrial control, auxiliary and equipment circuits against overloads and short circuits.
The IMO UB10D1008A has a rated operational current of 8 A.
A D curve circuit breaker has an instantaneous magnetic trip range of approximately 10 to 20 times its rated current, making it suitable for correctly designed circuits with high temporary inrush currents.
The UB10D1008A has a rated short-circuit breaking capacity of 10 kA.
Its rated operational voltages include 277 V AC under UL, 230 V AC under IEC and 48 V DC for a single-pole installation.
It can be used in appropriately designed circuits supplying transformers, industrial power supplies, contactors, solenoids and other equipment with high energisation currents.
It is designed for mounting on a standard DIN rail inside a suitable industrial control panel, machinery cabinet or electrical enclosure.
