The IMO UB10D1050A is a high-performance UL 489 miniature circuit breaker (MCB) engineered to provide reliable overload and short-circuit protection for industrial control panels, machinery and OEM electrical installations. Manufactured by IMO Precision Controls, this single-pole circuit breaker delivers dependable thermo-magnetic protection for demanding industrial applications.
Part of the proven IMO UB10 series, the UB10D1050A features a D curve tripping characteristic, making it ideal for circuits supplying motors, transformers, solenoids and other inductive loads with high inrush currents. Its compact DIN rail mounting design enables quick installation and seamless integration into modern electrical enclosures.
With a 50 A rated current, 10 kA short-circuit breaking capacity and compliance with UL 489, IEC 60947-2 and IEC 60898-1, the UB10D1050A delivers dependable branch circuit protection for industrial automation, machine building and commercial electrical systems.
Miniature circuit breakers automatically disconnect electrical circuits when overloads or short circuits occur, protecting wiring, machinery and connected equipment from damage. Thermo-magnetic protection combines thermal overload protection with rapid magnetic fault interruption to maximise system reliability.
The IMO UB10D1050A is particularly suited to industrial applications where motors and other inductive loads generate high start-up currents. Its D curve characteristic helps prevent nuisance tripping while maintaining dependable protection during genuine fault conditions.
