Why Choose the IMO US10C2004A UL1077 Miniature Circuit Breaker?
The IMO US10C2004A 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 delivers dependable supplementary protection for machinery, automation equipment, OEM systems and industrial control panels.
Designed for panel builders, machine manufacturers and maintenance engineers, the US10C2004A 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 motors, transformers, contactors, relays and other inductive electrical loads.
With a rated current of 4 A, a two-pole configuration and a 10 kA short circuit breaking capacity, the IMO US10C2004A provides reliable supplementary circuit protection while simultaneously isolating both poles of the protected circuit.
