Why Choose the IMO UB10D1016A Miniature Circuit Breaker?

The IMO UB10D1016A is a reliable UL 489 miniature circuit breaker (MCB) designed to protect electrical installations against overloads and short circuits. Manufactured by IMO Precision Controls, this industrial circuit breaker provides thermo-magnetic overcurrent protection for machinery, automation equipment and electrical control panels.

As part of the IMO UB10 series, the UB10D1016A features a D curve tripping characteristic with an instantaneous operating range of approximately 10 to 20 times the rated current. This makes it particularly suitable for circuits supplying equipment with high starting or inrush currents, including motors, transformers and inductive loads.

With a rated current of 16 A, a single-pole configuration and a 10 kA short-circuit breaking capacity, the UB10D1016A delivers dependable branch circuit protection in industrial environments. Its compact DIN rail mounting format enables straightforward installation inside control cabinets and distribution panels.

Reliable Protection for Industrial Electrical Systems

Miniature circuit breakers automatically disconnect a circuit when excessive current is detected, helping protect electrical wiring and connected equipment against overload and short-circuit damage. Thermo-magnetic operation combines thermal overload protection with rapid magnetic tripping during severe fault conditions.

The D curve characteristic of the IMO UB10D1016A allows equipment with high start-up currents to operate while maintaining dependable circuit protection. This makes the breaker well suited to industrial machinery, transformers, motor circuits and other inductive applications where a faster trip curve could cause unnecessary interruptions.

Typical Applications

  • Industrial control panels and electrical cabinets.
  • Electric motor and machinery circuits.
  • Transformers and inductive electrical loads.
  • OEM automation equipment.
  • Manufacturing and production machinery.
  • Branch circuit protection in industrial installations.
