Why Choose the IMO US10D2003A Miniature Circuit Breaker?

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.

Key Advantages

  • Dependable UL1077 supplementary circuit protection for industrial equipment.
  • 3 A rated current suitable for control and automation circuits.
  • 2 pole configuration for simultaneous protection and isolation.
  • D curve tripping characteristic for loads with high starting currents.
  • 10 kA short circuit breaking capacity for reliable fault interruption.
  • Compact DIN rail-mounted design simplifies control panel installation.

Key Features

  • IMO Precision Controls US10 series.
  • 3 A rated current.
  • 2 pole (2P) configuration.

Reliable Protection for Industrial Control Circuits

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.

Typical Applications

  • Industrial control panels and electrical cabinets.
  • Machine building and OEM equipment.
  • Transformer and power supply circuits.
  • Motor control and automation systems.
  • Solenoid and inductive load circuits.
  • Manufacturing and processing machinery.
