AA1-B0-14-650-5B1-C Description

Short technical summary and product information.

The AA1-B0-14-650-5B1-C is a single pole magnetic hydraulic delay circuit breaker from Littelfuse. It is rated for 50A continuous current at 277V AC. The breaker features a lever actuator and is designed for panel mount installation.

 

Magnetic hydraulic delay circuit breakers provide reliable overcurrent protection with a time delay characteristic that allows for temporary inrush currents without nuisance tripping. The hydraulic delay mechanism uses a solenoid and dashpot to provide inverse time-current curves.

 

This circuit breaker is approved by CCC, CSA, and UL, ensuring compliance with international safety standards. The compact 1-pole design is suitable for a variety of industrial and commercial applications requiring branch circuit protection.
