Why Choose the IMO UB10D3005A Miniature Circuit Breaker?
The IMO UB10D3005A 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 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 UB10D3005A is intended for circuits containing equipment that generates a high temporary starting current. It can accommodate the inrush associated with motors, transformers, solenoids and other inductive loads while maintaining dependable protection against sustained overcurrent and short-circuit faults.
With a rated current of 5 A, a 3-pole configuration and a 10 kA breaking capacity, the UB10D3005A provides simultaneous protection and isolation across three conductors. Its compact DIN rail-mounted format supports straightforward installation inside switchboards, distribution boards and industrial control enclosures.
Key Advantages
- Dependable overload and short-circuit protection.
- 5 A rated current for low-current three-phase circuits.
- D curve tripping characteristic suitable for high-inrush inductive loads.
- 3-pole configuration for simultaneous three-phase protection and isolation.
- 10 kA breaking capacity for reliable fault-current interruption.
- Compact DIN rail-mounted construction for convenient panel installation.
Key Features
- IMO UB10 series miniature circuit breaker.
- 5 A rated operational current.
- D curve instantaneous trip characteristic.
- Three-pole switching configuration.
- 10 kA short-circuit breaking capacity.
- Thermal protection against sustained overload currents.
- Magnetic protection against short-circuit faults.
- Designed for standard 35 mm DIN rail installation.
Reliable Protection for Three-Phase Industrial Circuits
Miniature circuit breakers automatically disconnect an electrical circuit when excessive current is detected. Thermal protection responds to sustained overload conditions, while the magnetic mechanism provides rapid disconnection during short-circuit faults, helping protect conductors, machinery and connected electrical equipment.
The D curve characteristic of the IMO UB10D3005A allows a higher temporary inrush current than more sensitive breaker curves. This makes it particularly suitable for transformers, motors, contactor coils, solenoids and other inductive devices that can 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.
