Why Choose the IMO US10D101.6A Miniature Circuit Breaker?
The IMO US10D101.6A is a compact UL1077 supplementary miniature circuit breaker (MCB) designed to protect industrial control circuits, OEM machinery and factory automation equipment against overload and short-circuit conditions. Manufactured by IMO Precision Controls, this single-pole breaker combines thermo-magnetic protection with a space-efficient DIN rail mounted construction.
Designed for panel builders, machine manufacturers and automation engineers, the US10D101.6A provides reliable supplementary protection for low-current circuits inside industrial electrical enclosures. Its modular format supports straightforward installation alongside relays, contactors, PLC equipment and power supplies.
Featuring a 1.6 A rated current, a D Curve tripping characteristic and a 10 kA short-circuit breaking capacity, the IMO US10D101.6A is particularly suitable for transformers, solenoids, contactor coils and other inductive loads that can produce high momentary inrush currents during energisation.
Key Advantages
- Compact UL1077 supplementary miniature circuit breaker.
- 1.6 A rated current for low-current industrial circuits.
- D Curve tripping characteristic suitable for high-inrush loads.

Reliable Protection for High-Inrush Control Circuits
The IMO US10D101.6A automatically disconnects the protected circuit when an overload or short-circuit condition occurs. This helps protect conductors, control devices and connected industrial equipment from electrical damage while supporting reliable machine operation and reduced unplanned downtime.
Its D Curve characteristic provides instantaneous magnetic tripping at approximately 10 to 20 times the rated current. This allows the breaker to tolerate short-duration start-up surges from inductive equipment without unnecessary nuisance tripping, while still providing dependable fault protection.
