The IMO US10D3030A is a compact UL1077 supplementary protector miniature circuit breaker designed to provide dependable overcurrent protection within industrial control equipment, OEM machinery and automation systems. Manufactured by IMO Precision Controls, it helps protect internal wiring and electrical components against sustained overload and short-circuit conditions.
Featuring a D Curve tripping characteristic, the US10D3030A is suitable for circuits containing equipment with relatively high temporary starting currents, including motors, transformers, contactors, solenoids and other inductive loads. Its thermal-magnetic operating mechanism combines overload protection with rapid fault interruption, helping minimise nuisance tripping during normal equipment start-up.
With a rated current of 30 A, a three-pole configuration and a 10 kA short-circuit breaking capacity, the IMO US10D3030A provides coordinated supplementary protection across three conductors. Its compact DIN rail-mounted construction supports straightforward integration into industrial control panels, machine cabinets and OEM electrical assemblies.
The IMO US10D3030A automatically disconnects protected circuits when excessive current is detected. This helps safeguard equipment wiring, control components and connected electrical devices from damage caused by overloads and short circuits while supporting reliable machine operation.
Its D Curve operating characteristic allows the breaker to tolerate brief energisation currents without unnecessary tripping, making it particularly suitable for inductive industrial loads. The three-pole arrangement provides simultaneous protection and isolation across three conductors in automation equipment and three-phase machinery circuits.
