Why Choose the IMO UB10C3020A Miniature Circuit Breaker?
The IMO UB10C3020A is a robust and compact three-pole miniature circuit breaker (MCB) designed to protect industrial electrical circuits against overload and short-circuit conditions. Part of the dependable IMO UB10 circuit breaker series, it provides reliable branch circuit protection for machinery, automation equipment and electrical distribution systems.
This miniature circuit breaker features a C curve tripping characteristic, allowing it to accommodate the moderate inrush currents commonly produced by motors, transformers, solenoids and industrial control equipment. Its thermal-magnetic operating mechanism provides effective protection against sustained overloads and high-current electrical faults.
With a rated current of 20 A, a three-pole configuration and a 10 kA short-circuit breaking capacity, the UB10C3020A is suitable for three-phase industrial applications. Its DIN rail mounted design allows straightforward installation within control panels, machinery cabinets and electrical distribution enclosures.

Reliable Circuit Protection for Industrial Systems
Miniature circuit breakers automatically disconnect an electrical supply when excessive current is detected. This helps protect cables, machinery and connected equipment from damage caused by overloads, short circuits and electrical faults while improving installation safety and reliability.
The C curve response of the IMO UB10C3020A makes it particularly suitable for equipment that produces temporary current surges during start-up. Its three-pole switching arrangement disconnects all protected phases together, providing coordinated protection for three-phase machinery and industrial power circuits.
Typical Applications
- Industrial control panels and electrical cabinets.
- Three-phase machinery circuits.
- Motor and transformer supply circuits.
- Factory automation and production equipment.
- Commercial and industrial distribution boards.
- OEM machinery and process-control systems.
