Why Choose the IMO UB10D3006A Miniature Circuit Breaker?
The IMO UB10D3006A is a compact 3-pole miniature circuit breaker (MCB) designed to protect three-phase electrical circuits against overload and short-circuit conditions. Part of the established IMO UB10 circuit protection range, it is suitable for industrial control panels, automation equipment, OEM machinery and commercial electrical distribution systems.
Featuring a D curve tripping characteristic, the UB10D3006A is designed for circuits containing equipment with high temporary starting currents. It can accommodate the inrush generated by motors, transformers, solenoids, contactor coils and other inductive loads while maintaining dependable protection against sustained overloads and short-circuit faults.
With a rated current of 6 A, a 3-pole configuration and a 10 kA breaking capacity, the UB10D3006A provides simultaneous protection and isolation across three conductors. Its DIN rail-mounted format enables straightforward integration into distribution boards, switchboards and industrial control enclosures.

Reliable Protection for Three-Phase Industrial Circuits
The IMO UB10D3006A automatically disconnects an electrical circuit when excessive current is detected. Its thermal element responds to sustained overload conditions, while the magnetic mechanism provides rapid disconnection during short-circuit faults, helping to protect conductors, machinery and connected electrical equipment.
The D curve characteristic permits a higher temporary inrush current than B or C curve breakers before magnetic tripping occurs. This makes the UB10D3006A particularly suitable for transformers, motors, solenoids, contactor coils and other inductive devices that may draw a significant current surge when energised.
Typical Applications
- Industrial control panels.
- Three-phase control and auxiliary circuits.
- Control transformers and power supplies.
- Motor starter circuits.
- Solenoids, contactor coils and inductive loads.
- Industrial automation systems.
- OEM machinery and electrical enclosures.
