Why Choose the IMO UB10C2010A Miniature Circuit Breaker?
The IMO UB10C2010A is a compact UL 489 miniature circuit breaker (MCB) designed to protect electrical installations against overloads and short circuits. Part of the IMO UB10 Series, this two-pole device provides dependable branch circuit protection for industrial control panels, machinery, automation systems and electrical distribution equipment.
Featuring a 10 A rated current, two-pole configuration, C curve operating characteristic and 10 kA short-circuit breaking capacity, the UB10C2010A is suitable for circuits with moderate start-up currents. Its linked two-pole construction enables both conductors to be disconnected together when an overload or short-circuit fault occurs.
The thermal-magnetic trip mechanism combines sustained overload protection with rapid interruption of high fault currents. A contact-position indicator supports straightforward status checking, while the compact DIN rail mounting format helps simplify installation in control cabinets, machinery enclosures and distribution boards.

Reliable Thermal-Magnetic Circuit Protection
The IMO UB10C2010A uses two complementary tripping methods. Its thermal element responds to sustained overload currents that could otherwise overheat wiring or connected equipment, while its magnetic element provides rapid disconnection during high-current short circuits.
The C curve operating characteristic trips magnetically between five and ten times the breaker’s rated current. This makes the UB10C2010A suitable for many industrial circuits containing equipment that can draw a brief, moderate inrush current during start-up.
Typical Applications
- Industrial control panels.
- PLC and automation systems.
- Control transformers and power supplies.
- Machinery and production equipment.
- OEM electrical assemblies.
- Commercial and industrial distribution boards.
- Branch circuit protection.
