AA1-B0-26-625-321-C Description

Short technical summary and product information.

The Littelfuse AA1-B0-26-625-321-C is a single-pole magnetic hydraulic delay circuit breaker rated for 25A continuous current at 277V AC/DC. It features a lever actuator and is designed for panel mount installation. The magnetic hydraulic delay mechanism provides precise overcurrent protection with time-delay characteristics suitable for handling inrush currents without nuisance tripping.

 

This circuit breaker is approved by CCC, CSA, and UL, ensuring compliance with international safety standards. The non-illuminated design simplifies installation in applications where visual indication is not required. The compact single-pole form factor makes it suitable for branch circuit protection in industrial control panels, power distribution units, and equipment requiring reliable overcurrent protection.

 

Panel mount configuration allows for easy integration into enclosures and control cabinets. The lever actuator provides clear visual indication of the breaker state and manual reset capability. With a 25A rating and 277V voltage rating, this breaker is well-suited for lighting circuits, motor protection, and general-purpose power distribution in commercial and industrial environments.
