Why Choose the IMO US10D1004A Miniature Circuit Breaker?
The IMO US10D1004A is a compact and dependable UL1077 supplementary miniature circuit breaker (MCB) designed to protect industrial control circuits, OEM machinery and automation equipment against overload and short-circuit conditions. Manufactured by IMO Precision Controls, this single-pole circuit breaker combines reliable electrical protection with a space-saving DIN rail mounted format.
Developed for panel builders, machine manufacturers and automation engineers, the US10D1004A provides dependable supplementary circuit protection within industrial electrical enclosures. Its compact construction enables efficient control-panel layouts, while its thermo-magnetic operating mechanism provides automatic circuit isolation when excessive current or a short-circuit fault is detected.
With a rated current of 4 A, a D Curve tripping characteristic and a 10 kA short-circuit breaking capacity, the IMO US10D1004A is particularly suitable for circuits containing transformers, solenoids, contactor coils and other inductive loads that can generate high momentary inrush currents.
Key Advantages
- Compact supplementary miniature circuit breaker for industrial applications.
- 4 A rated current suitable for control and auxiliary circuits.
- D Curve tripping characteristic designed for high-inrush electrical loads.
- 10 kA breaking capacity for dependable short-circuit interruption.
- Single-pole design helps maximise available control-panel space.
- DIN rail mounting supports quick installation and straightforward maintenance.
Key Features
- IMO Precision Controls US10D series.
- 4 A rated current.
- Single-pole configuration.
- D Curve trip characteristic.
- 10 kA interrupting capacity.
- UL1077 supplementary circuit protection.
- Thermo-magnetic overload and short-circuit protection.
- Compact DIN rail mounted construction.
Reliable Protection for High-Inrush Control Circuits
The IMO US10D1004A automatically disconnects the protected circuit when an overload or short-circuit condition occurs. This helps prevent damage to wiring, control components and connected machinery while supporting improved system reliability and reduced unplanned downtime.
Its D Curve operating characteristic allows the breaker to tolerate higher momentary start-up currents than more sensitive trip curves. This makes it particularly suitable for transformers, coils, solenoids, contactors and industrial power supplies where normal energisation can produce a substantial temporary current surge.
Typical Applications
- Industrial control panels.
- OEM machinery and production equipment.
- Transformer protection circuits.
- Solenoid and contactor coil circuits.
- Industrial power supplies.
- Factory automation systems.
- Control and instrumentation circuits.
