The IMO US10C2040A is a compact, high-performance UL1077 supplementary miniature circuit breaker designed to protect industrial control circuits against overload and short-circuit conditions. Manufactured by IMO Precision Controls, this two-pole protective device is suitable for machine builders, panel manufacturers and automation engineers requiring dependable circuit protection in demanding electrical installations.
Featuring a C curve tripping characteristic, the US10C2040A is designed to tolerate the moderate inrush currents commonly associated with motors, transformers, contactors and switched-mode power supplies. Its thermal-magnetic operating mechanism combines dependable overload protection with rapid fault interruption, helping safeguard connected wiring and industrial equipment.
With a 40 A rated current, 2-pole configuration and 10 kA short-circuit breaking capacity, the IMO US10C2040A delivers reliable supplementary protection for industrial machinery and control systems. Its modular DIN rail-mounted design allows straightforward installation within control cabinets, distribution enclosures and OEM equipment.
The IMO US10C2040A automatically disconnects an electrical circuit when excessive current is detected. Its thermal element responds to sustained overload conditions, while its magnetic mechanism rapidly interrupts higher-current short circuits. This dual-action design helps reduce the risk of damage to cabling, machinery and electrical control components.
As a UL1077 supplementary protector, the US10C2040A is intended for installation within electrical equipment where suitable branch-circuit protection is already provided. Its compact modular construction makes it particularly well suited to industrial control panels and machinery enclosures where panel space is limited.

The US10C2040A provides supplementary overload and short-circuit protection for industrial control panels, machinery and automation equipment.
The IMO US10C2040A has a rated operational current of 40 A.
The US10C2040A has a 2-pole configuration, allowing two conductors to be protected and disconnected together.
The C curve magnetic trip operates at approximately five to ten times the rated current, making the breaker suitable for circuits with moderate start-up or inrush currents.
The two-pole breaker is rated for up to 480Y/277 V AC under UL specifications, 415 V AC under IEC specifications and 96 V DC.
The breaker is designed for mounting on a standard EN 60715 DIN rail inside an electrical control panel or machinery enclosure.
