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.
