AA1-B2-11-630-3B2-C Description

Short technical summary and product information.

The Littelfuse AA1-B2-11-630-3B2-C is a 1-pole magnetic hydraulic delay circuit breaker designed for overcurrent protection. It is rated for 30A continuous current at 277V AC, making it suitable for applications requiring reliable circuit interruption.

 

The breaker uses a magnetic hydraulic delay mechanism to provide time-delayed tripping, which helps avoid nuisance tripping during temporary overloads. The lever actuator allows manual reset and on/off control. It is panel mounted, simplifying installation in control panels and distribution boards.

 

This component is part of Littelfuse's AA1 series. It is listed as RoHS compliant, but this has not been verified from official documentation. The distributor part number is 432-AA1-B2-11-630-3B2-C-ND.
