Why Choose the IMO US10C2005A UL1077 Miniature Circuit Breaker?
The IMO US10C2005A is a compact UL1077 supplementary miniature circuit breaker (MCB) designed to protect industrial control circuits against overload and short circuit conditions. Manufactured by IMO Precision Controls, it provides dependable supplementary protection for automation equipment, machinery, OEM systems and industrial control panels.
Designed for panel builders, machine manufacturers and maintenance engineers, the US10C2005A combines thermal-magnetic protection with a space-saving DIN rail mounted design. Its C curve tripping characteristic accommodates moderate temporary inrush currents, making it suitable for transformers, contactors, relays, solenoids, power supplies and other inductive loads.
With a rated current of 5 A, a two-pole configuration and a 10 kA short circuit breaking capacity, the IMO US10C2005A provides reliable supplementary circuit protection while enabling simultaneous isolation of both poles.

Reliable Two-Pole Protection for Industrial Control Systems
The IMO US10C2005A automatically disconnects both poles of the protected circuit whenever an overload or short circuit occurs. Its thermal element responds to sustained overcurrent conditions, while the magnetic mechanism reacts rapidly to high fault currents, helping protect valuable industrial equipment and minimise unplanned downtime.
The mechanically linked two-pole design provides simultaneous switching and convenient circuit isolation. This makes the breaker suitable for control power supplies, instrumentation circuits, PLC systems and other industrial automation applications requiring dependable supplementary protection.
Typical Applications
- Industrial control panels.
- PLC and automation systems.
- Instrumentation and monitoring equipment.
- Control transformers and power supplies.
- Relays, contactors and solenoids.
- Machine building and OEM equipment.
