Why Choose the IMO US10D3004A UL1077 Miniature Circuit Breaker?
The IMO US10D3004A is a compact and dependable UL1077 supplementary protector miniature circuit breaker designed to protect industrial control circuits, automation equipment and electrical machinery against overload and short-circuit conditions. Manufactured by IMO Precision Controls, it provides reliable supplementary circuit protection for panel builders, machine manufacturers and industrial maintenance applications.
This supplementary protector features a D Curve tripping characteristic, allowing it to accommodate the temporary high inrush currents commonly produced by motors, transformers, solenoids, contactors and other inductive loads. Its thermal-magnetic operating mechanism provides effective overload and short-circuit protection, while its compact modular construction helps conserve valuable space inside electrical control cabinets.
With a rated current of 4 A, a three-pole configuration and a 10 kA short-circuit breaking capacity, the US10D3004A is suitable for low-current three-phase control and equipment circuits requiring dependable supplementary overcurrent protection. Its DIN rail mounting format enables straightforward integration into industrial control panels, automation systems and OEM machinery.
