The 1B50UR is a miniature circuit breaker manufactured by Altech Corporation. It is rated for 50A continuous current and 277V AC voltage, featuring a single pole configuration. The breaker uses a thermal magnetic trip mechanism to provide both overload and short circuit protection.
The actuator type is a lever for manual switching. This unit is designed for DIN Rail mounting, making it suitable for installation in standard industrial enclosures and distribution panels. The illumination is none, indicating no visual indication of trip status.
Typical applications include branch circuit protection in industrial control panels, lighting circuits, and power distribution systems. The compact 1-pole design saves space in multi-pole breaker assemblies.
