Why Choose the IMO US10C2003A UL1077 Miniature Circuit Breaker?
The IMO US10C2003A 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 US10C2003A combines reliable 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, relays, contactors, power supplies and other inductive electrical loads.
With a rated current of 3 A, a two-pole configuration and a 10 kA short circuit breaking capacity, the IMO US10C2003A provides dependable supplementary circuit protection while enabling simultaneous isolation of both poles.
Key Advantages
- Compact UL1077 supplementary protector for industrial control applications.
- 3 A current rating suitable for low-current control and automation circuits.
- Two-pole configuration for simultaneous isolation of both conductors.
- 10 kA breaking capacity for dependable short circuit protection.
- C curve tripping characteristic suitable for moderate inrush currents.
- Quick installation onto a standard 35 mm DIN rail.
Key Features
- IMO US10 UL1077 series.
- 3 A rated current.
