AA1-B0-34-610-221-C Description

Short technical summary and product information.

The Littelfuse AA1-B0-34-610-221-C is a single-pole magnetic hydraulic delay circuit breaker designed for overcurrent protection in electrical systems. It is rated for 10A continuous current at 277V AC, making it suitable for branch circuit protection in commercial and industrial applications.

 

The breaker uses a magnetic hydraulic delay mechanism, which provides precise and reliable trip characteristics. The hydraulic delay allows for momentary inrush currents without nuisance tripping, while still providing fast protection against sustained overloads and short circuits. The lever actuator offers a clear visual indication of the breaker state.

 

This circuit breaker is panel mounted, allowing for secure installation in control panels and distribution enclosures. It is certified by CCC, CSA, and UL, ensuring compliance with international safety standards.
