AF1-B0-34-450-1G3-C Description

Short technical summary and product information.

The Littelfuse AF1-B0-34-450-1G3-C is a single-pole magnetic circuit breaker with hydraulic delay, rated for 5A continuous current and 277V AC/DC. It uses a magnetic (hydraulic delay) trip mechanism, providing time-delayed overcurrent protection suitable for applications with moderate inrush currents.

 

The breaker is equipped with a rocker actuator and is designed for panel mount installation. It has no illumination. This model is approved by CCC, CSA, and UL, making it suitable for use in various commercial and industrial equipment requiring reliable circuit protection.

 

The compact 1-pole design integrates easily into control panels and distribution boards. The hydraulic delay allows for tolerance of temporary current surges without nuisance tripping, while ensuring fast disconnect under sustained fault conditions.
