AA1-B0-24-625-5D7-C Description

Short technical summary and product information.

The AA1-B0-24-625-5D7-C is a single-pole magnetic (hydraulic delay) circuit breaker manufactured by Littelfuse Inc. This component is designed for overcurrent protection in electrical circuits, utilizing a hydraulic-magnetic mechanism that provides precise and reliable tripping characteristics. The hydraulic delay feature allows for tolerance of temporary inrush currents without nuisance tripping, making it suitable for applications with inductive or capacitive loads.

 

Key electrical specifications include a current rating of 25A and a voltage rating of 277V. The breaker is actuated by a lever mechanism and is designed for panel mount installation with a snap-in feature for secure and convenient mounting. It is approved by CCC, CSA, and UL, indicating compliance with major international safety standards.

 

This circuit breaker is commonly used in power distribution, industrial control panels, and equipment requiring reliable overcurrent protection. Its magnetic trip mechanism ensures fast response to short circuits while the hydraulic delay provides time-delayed tripping for overload conditions.
