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.

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.
