The IMO US10D2003A is a compact and dependable UL1077 supplementary miniature circuit breaker (MCB) designed to protect industrial control circuits, machinery and automation equipment against overload and short circuit conditions. Manufactured by IMO Precision Controls, this circuit protection device combines reliable electrical performance with a space-saving DIN rail-mounted format.
The US10D2003A features a 10 kA short circuit breaking capacity and a D curve tripping characteristic. This tripping profile allows the breaker to accommodate high temporary inrush currents, making it particularly suitable for transformers, motors, solenoids, power supplies and other inductive electrical loads.
With a rated current of 3 A and a 2 pole configuration, the IMO US10D2003A provides simultaneous protection and isolation of two conductors. Its robust construction and straightforward installation make it an effective choice for panel builders, machine manufacturers and industrial automation engineers.
Supplementary miniature circuit breakers protect electrical equipment by automatically interrupting the circuit when excessive current or a short circuit is detected. This helps reduce the risk of component damage, improve system reliability and minimise downtime within industrial installations.
The D curve response of the IMO US10D2003A is well suited to equipment that produces high inrush currents during start-up. It helps prevent nuisance tripping under normal operating conditions while maintaining dependable protection against sustained overloads and electrical faults.

The US10D2003A is a supplementary miniature circuit breaker used to protect industrial control circuits and electrical equipment against overloads and short circuits.
The IMO US10D2003A has a rated current of 3 A, making it suitable for low-current industrial control and automation circuits.
A D curve circuit breaker can tolerate relatively high temporary inrush currents, making it suitable for transformers, motors, solenoids and other inductive loads.
The US10D2003A has a 2 pole configuration, allowing two conductors to be disconnected simultaneously when the breaker operates.
The breaker is designed for installation on a standard DIN rail inside an industrial control panel, machine cabinet or electrical enclosure.
IMO supplementary miniature circuit breakers provide panel builders, machine manufacturers and automation engineers with compact, reliable protection for industrial control circuits and electrical equipment.
