Why Choose the IMO US10D3020A UL1077 Miniature Circuit Breaker?
The IMO US10D3020A is a compact and dependable UL1077 supplementary protector miniature circuit breaker designed to provide reliable overcurrent protection for industrial control circuits, OEM machinery and automation systems. Manufactured by IMO Precision Controls, it helps protect internal equipment wiring and electrical components against overload and short-circuit conditions.
Featuring a D Curve tripping characteristic, the US10D3020A is suited to circuits containing equipment with high temporary starting currents, including motors, transformers, contactors, solenoids and other inductive loads. Its thermal-magnetic operating mechanism combines overload protection with rapid short-circuit interruption, while its compact modular construction supports space-efficient installation inside electrical control panels.
With a rated current of 20 A, a three-pole configuration and a 10 kA short-circuit breaking capacity, the IMO US10D3020A provides coordinated supplementary protection for three-phase equipment circuits. Its DIN rail mounting format enables straightforward integration into industrial automation systems, machine control cabinets and OEM electrical assemblies.
