Why Choose the IMO UB10C2003A Miniature Circuit Breaker?
The IMO UB10C2003A is a compact UL 489 miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the IMO UB10 circuit breaker series, it provides dependable branch circuit protection for industrial control panels, machinery, automation equipment and electrical distribution systems.
Featuring a 3 A rated current, a two-pole configuration, a C curve trip characteristic and a 10 kA short-circuit interrupting capacity, the UB10C2003A is well suited to control, auxiliary and instrumentation circuits that may experience moderate start-up currents. Its mechanically linked two-pole construction enables both connected conductors to be disconnected simultaneously when a fault occurs.
The UB10C2003A combines thermal overload protection with rapid magnetic short-circuit protection, helping to safeguard wiring, power supplies and connected control equipment. Its compact DIN rail mounting format supports efficient installation in industrial machinery panels, OEM equipment and electrical distribution enclosures.

Reliable Protection for Industrial Control Circuits
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected. The thermal trip mechanism responds to sustained overload conditions, while the magnetic trip mechanism provides rapid isolation during high-current short circuits. This combined operation helps reduce the risk of damage to wiring and connected electrical equipment.
The C curve operating characteristic allows the UB10C2003A to tolerate moderate momentary inrush currents while maintaining effective overload and short-circuit protection. Its two-pole construction makes it suitable for circuits where simultaneous disconnection of both conductors is required.
Typical Applications
- Industrial control and auxiliary circuits.
- PLC and automation systems.
- Instrumentation and monitoring equipment.
- Control transformers and power supplies.
- OEM machinery and electrical control panels.
- Commercial and industrial distribution equipment.
