Why Choose the IMO US10C200.5A UL1077 Miniature Circuit Breaker?
The IMO US10C200.5A is a compact UL1077 supplementary miniature circuit breaker (MCB) designed to protect low-current industrial control circuits against overload and short circuit conditions. Manufactured by IMO Precision Controls, it provides dependable supplementary protection for automation equipment, control panels, machinery and OEM electrical systems.
Designed for panel builders, machine manufacturers and industrial maintenance engineers, the US10C200.5A combines thermal-magnetic protection with a space-saving DIN rail mounted format. Its C curve tripping characteristic accommodates moderate temporary inrush currents while maintaining sensitive protection for low-current control and instrumentation circuits.
With a rated current of 0.5 A, a two-pole configuration and a 10 kA short circuit breaking capacity, the IMO US10C200.5A enables simultaneous disconnection of two conductors and helps reduce equipment damage, electrical downtime and maintenance requirements.

Sensitive Two-Pole Protection for Control Circuits
The IMO US10C200.5A automatically disconnects the protected circuit when excessive current is detected. Its thermal element responds to sustained overload conditions, while its magnetic mechanism provides rapid operation during high-current short circuits.
The mechanically linked two-pole design disconnects both poles together, providing convenient circuit isolation and improved protection for two-wire control supplies. Its low 0.5 A rating makes it particularly suitable for sensitive electrical equipment, instrumentation, PLC circuits and industrial control devices.
Typical Applications
- Industrial control panels.
- PLC and automation control circuits.
- Instrumentation and monitoring equipment.
- Low-current power supplies.
- Sensors, relays and control devices.
- Machine building and OEM equipment.
