AA1-B0-12-610-2B1-C Description

Short technical summary and product information.

The Littelfuse AA1-B0-12-610-2B1-C is a single-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in electrical systems. It is rated for 10A continuous current at 277V AC, making it suitable for branch circuit and equipment protection in commercial and industrial applications.

 

The breaker uses a magnetic (hydraulic delay) trip mechanism, which provides precise and reliable overcurrent protection while allowing for temporary inrush currents without nuisance tripping. The lever actuator offers clear visual indication of the breaker state and allows for manual reset.

 

This component is panel mounted, simplifying installation into control panels, distribution boards, and equipment enclosures. It is approved by CCC, CSA, and UL, indicating compliance with major international safety standards.
