The IMO US10C1005A is a compact UL 1077 miniature circuit breaker designed to provide supplementary overload and short circuit protection for electrical equipment and internal control circuits. Manufactured by IMO Precision Controls, this DIN rail-mounted protective device is suitable for industrial machinery, automation systems, OEM equipment and electrical control panels.
Featuring a single-pole configuration, a 5 A rated operational current and a C curve tripping characteristic, the US10C1005A is well suited to circuits that may experience moderate temporary inrush currents during normal operation. Its thermo-magnetic protection mechanism helps safeguard control devices, power supplies, instrumentation and other electrical loads against sustained overloads and short circuit faults.
The US10C1005A offers a 10 kA rated short circuit breaking capacity, a UL operational voltage rating of up to 277 V AC for single-pole applications and an IEC operational voltage rating of 230 V AC. Its compact construction and standard DIN rail mounting help minimise panel space while supporting straightforward installation and maintenance.
The IMO US10C1005A combines thermal and magnetic tripping technologies within one compact protective device. The thermal element responds to prolonged overload conditions, while the magnetic element operates rapidly during high-current short circuit faults. This dual-action design helps reduce the risk of damage to internal wiring, electrical components and connected equipment.
Its C curve characteristic provides instantaneous magnetic operation at approximately five to ten times the rated current. This makes the US10C1005A suitable for circuits containing control transformers, power supplies, contactor coils and other equipment that may produce a moderate start-up current without indicating a fault.

The US10C1005A is used to provide supplementary overload and short circuit protection for electrical equipment, control circuits, automation systems and internal panel wiring.
The IMO US10C1005A has a rated operational current of 5 A.
The C curve characteristic provides instantaneous magnetic tripping at approximately five to ten times the rated current, allowing the device to tolerate moderate temporary inrush currents.
The US10C1005A has a rated short circuit breaking capacity of 10 kA.
For single-pole applications, the device is rated up to 277 V AC under UL specifications, 230 V AC under IEC specifications and 48 V DC.
The US10C1005A is a UL 1077 supplementary protector intended for equipment-level protection. It should be installed with suitable upstream branch circuit protection wherever required by the applicable electrical regulations.
