Why Choose the IMO UB10D2050A Miniature Circuit Breaker?
The IMO UB10D2050A is a robust 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions. Part of the IMO UB10 circuit protection range, this compact breaker is suited to industrial machinery, commercial distribution systems, OEM equipment and electrical control panels.
Featuring a D curve tripping characteristic, the UB10D2050A is designed for circuits that experience substantial temporary starting currents. This makes it particularly suitable for motors, transformers, solenoids and other inductive loads that may cause nuisance tripping when protected by a more sensitive breaker characteristic.
With a rated current of 50 A, a 2-pole configuration and a short-circuit breaking capacity of 10 kA, the UB10D2050A provides dependable circuit protection and simultaneous isolation of two conductors. Its DIN rail-mounted construction enables straightforward installation inside distribution boards, switchboards and industrial control cabinets.
Key Advantages
- Dependable overload and short-circuit protection.
- 50 A rated current for demanding industrial and commercial circuits.
- D curve tripping characteristic suitable for high-inrush electrical loads.
- 2-pole configuration for simultaneous switching and isolation.
- 10 kA breaking capacity for reliable fault-current interruption.
- Compact DIN rail-mounted design simplifies panel installation.
Key Features
- IMO UB10 series miniature circuit breaker.
- 50 A rated operational current.
- D curve instantaneous trip characteristic.
- Two-pole switching configuration.
- 10 kA short-circuit breaking capacity.
- Thermal protection against sustained overload currents.
- Magnetic protection against short-circuit faults.
- Compact construction for standard 35 mm DIN rail installation.
Reliable Protection for High-Inrush Electrical Circuits
Miniature circuit breakers automatically disconnect electrical circuits when excessive current is detected, helping protect wiring, machinery and connected equipment from damage. Thermal protection responds to prolonged overload conditions, while magnetic protection provides rapid disconnection during short-circuit faults.
The D curve characteristic of the IMO UB10D2050A permits higher temporary inrush currents than standard B curve or C curve breakers. This makes it particularly suitable for motors, transformers and industrial equipment that draw substantial current during start-up.
Typical Applications
- Industrial motors and motor control circuits.
- Transformers and power distribution equipment.
- Industrial machinery and automation systems.
- Commercial and industrial distribution boards.
- Solenoids, coils and other inductive loads.
- OEM control panels and electrical enclosures.
