Why Choose the IMO US10C1004A Supplementary Protector?
The IMO US10C1004A is a compact UL1077 supplementary protector designed to provide dependable overload and short circuit protection for electrical equipment and internal control circuits. Manufactured by IMO Precision Controls, this DIN rail-mounted protective device is ideal for industrial machinery, automation systems, OEM equipment and electrical control panels requiring reliable equipment-level protection.
Featuring a single-pole configuration, a 4 A rated current and a C curve tripping characteristic, the US10C1004A is ideal for protecting low-current circuits with moderate inrush requirements. Its thermal-magnetic operating mechanism provides dependable protection for PLCs, instrumentation, control devices, sensors, power supplies and other sensitive electrical equipment.
With a 10 kA short circuit breaking capacity, compact modular construction and DIN rail mounting, the US10C1004A delivers reliable fault protection while occupying minimal control panel space. It is designed for use as a supplementary protector alongside an appropriate upstream branch circuit protective device.

Reliable Protection for Control and Equipment Circuits
Supplementary protectors automatically disconnect electrical circuits when excessive current is detected. The thermal element responds to sustained overload conditions, while the magnetic element provides rapid operation during short circuit faults. This helps protect internal wiring, sensitive electronic components and connected equipment from electrical damage.
The C curve characteristic of the IMO US10C1004A allows moderate temporary inrush currents before magnetic tripping occurs. This makes it suitable for control equipment and electrical devices that experience brief start-up currents while maintaining dependable protection against genuine electrical faults.
Typical Applications
- Industrial control circuits.
- PLC and automation systems.
- Instrumentation and monitoring equipment.
- Low-current power supply circuits.
- Machine building and OEM equipment.
- Internal equipment protection.
