Why Choose the IMO UB10D200.5A Miniature Circuit Breaker?

The IMO UB10D200.5A is a high-performance UL 489 miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection for industrial electrical installations. Manufactured by IMO Precision Controls, this 2-pole circuit breaker incorporates thermo-magnetic protection to safeguard machinery, automation equipment and electrical control systems. The model features a 0.5 A rated current, D curve tripping characteristic and a 10 kA short-circuit breaking capacity.

As part of the established IMO UB10 UL 489 miniature circuit breaker range, the UB10D200.5A is designed for applications where temporary inrush currents occur. The D curve characteristic provides instantaneous magnetic tripping at approximately 10 to 20 times the rated current, making it suitable for motors, transformers, solenoids and other inductive loads.

Its compact DIN rail mounting format, robust construction and recognised industrial approvals make the UB10D200.5A an excellent choice for machine builders, panel manufacturers and industrial automation engineers requiring reliable branch circuit protection.

Key Advantages

  • Industrial UL 489 miniature circuit breaker.
  • 0.5 A rated operational current.
  • 2-pole configuration for two-pole circuit protection.
  • D curve tripping characteristic for high inrush current loads.
  • 10 kA short-circuit breaking capacity.
  • Thermo-magnetic protection against overloads and short circuits.
  • Compact DIN rail mounting for industrial control panels.

Key Features

  • IMO UB10 UL 489 miniature circuit breaker series.
  • 0.5 A rated current.
  • 2-pole design.
  • D curve operating characteristic.
  • 10 kA breaking capacity.
  • Compliant with UL 489.
  • Contact position indicator.

Reliable Protection for Industrial Electrical Systems

Miniature circuit breakers automatically disconnect electrical circuits whenever overloads or short circuits occur. Thermo-magnetic protection combines thermal overload detection with rapid magnetic fault interruption, helping protect wiring, machinery and electrical equipment from damage.

The D curve characteristic makes the IMO UB10D200.5A particularly suitable for industrial applications involving motors and other inductive loads that generate temporary start-up currents, reducing nuisance tripping while maintaining dependable protection during fault conditions.

Typical Applications

  • Industrial control panels.
  • Machine building.
  • OEM automation equipment.
  • Motor and transformer circuits.
  • Industrial electrical distribution.
  • Automation systems.
