AA1-B0-34-450-1G1-C Description

Short technical summary and product information.

The Littelfuse AA1-B0-34-450-1G1-C is a single-pole magnetic hydraulic delay circuit breaker designed for reliable overcurrent protection. It is rated for 5 amps continuous current at 277 volts AC/DC. The magnetic hydraulic actuation provides precise time-current tripping characteristics with immunity to ambient temperature variations.

 

The circuit breaker features a panel mount installation with a lever actuator for manual reset. It offers a compact single-pole form factor suitable for branch circuit protection and control panel applications. The housing is non-illuminated and designed for robust industrial use.

 

This breaker is part of the AA1 series from Littelfuse, a leading manufacturer of circuit protection components. The hydraulic-magnetic mechanism allows for fast interruption of high fault currents while maintaining high reliability in demanding environments.
