AF1-B0-44-475-133-D Description

Short technical summary and product information.

The AF1-B0-44-475-133-D is a single-pole magnetic circuit breaker from Littelfuse Inc. featuring a hydraulic delay mechanism. It is rated for 7.5A continuous current at 250V AC/DC, making it suitable for overcurrent protection in a variety of applications.

 

The breaker uses a magnetic (hydraulic delay) trip mechanism, which provides predictable time-delay characteristics and is less sensitive to ambient temperature changes than thermal breakers. The rocker actuator allows for manual on/off control and manual reset after a trip event.

 

This component is designed for panel mount installation, offering a robust and secure fit for equipment enclosures. The non-illuminated rocker provides a clean, simple interface.
