BA1-B0-22-450-221-D Description

Short technical summary and product information.

The Littelfuse BA1-B0-22-450-221-D is a single-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in a variety of applications. It is rated for 5A continuous current at 250V AC/DC, providing reliable circuit interruption under fault conditions.

 

The breaker uses a magnetic (hydraulic delay) trip mechanism, which offers precise and repeatable trip characteristics while being less sensitive to ambient temperature changes than thermal breakers. The lever actuator allows for manual reset and on/off control.

 

This component is designed for panel mount installation, making it suitable for use in control panels, power distribution units, and industrial equipment where a robust, front-accessible circuit protection device is required.
