Why Choose the IMO UB10B1050A 50 A Type B Miniature Circuit Breaker?
The IMO UB10B1050A is a robust and compact single-pole miniature circuit breaker (MCB) designed to protect low-voltage electrical circuits against overloads and short circuits. Manufactured by IMO Precision Controls, it provides dependable circuit protection for industrial machinery, commercial electrical systems and control-panel installations.
This miniature circuit breaker features a Type B tripping characteristic, making it suitable for circuits where relatively low levels of inrush current are expected. It combines thermal overload protection with rapid magnetic short-circuit protection, helping prevent damage to cables, equipment and connected electrical components.
With a rated current of 50 A, a high 10 kA short-circuit breaking capacity and a space-saving single-pole configuration, the UB10B1050A is ideal for modular distribution boards, industrial control cabinets and OEM equipment. Its standard DIN rail mounting format enables straightforward installation alongside compatible switching and protection devices.
Key Advantages
- Reliable overload and short-circuit protection.
- 50 A rated current for higher-current electrical circuits.
- Type B tripping characteristic for circuits with limited inrush current.

Reliable Protection for Low-Voltage Electrical Circuits
Miniature circuit breakers such as the IMO UB10B1050A automatically disconnect an electrical circuit when excessive current is detected. The thermal element responds to sustained overload conditions, while the magnetic trip mechanism provides fast disconnection during high-current short circuits.
The Type B operating characteristic is intended for circuits that do not normally experience significant starting currents. This makes the UB10B1050A suitable for compatible resistive loads, distribution circuits, electrical heating systems and control applications requiring reliable 50 A protection.
Typical Applications
- Industrial electrical control panels.
- Commercial distribution boards.
- Resistive heating circuits.
- Machinery power and control circuits.
- Building-services electrical systems.
- OEM equipment and automation installations.
