GFA-1 Description

Short technical summary and product information.

The Eaton GFA-1 is a subminiature board mount fuse designed for through hole mounting with axial leads. It is rated for 1A of current at 125VAC and features a fast blow response time for sensitive circuit protection.

 

This fuse has a breaking capacity of 50A at rated voltage, suitable for protecting subminiature devices from overcurrent conditions. The glass tube construction with tinned wire leads allows for reliable soldering into circuits and can withstand high-shock and vibration environments.

 

The GFA-1 is part of the GFA series and comes in a cartridge, non-standard (axial) package measuring 0.146" diameter by 0.299" length (3.70mm x 7.60mm). It is color-coded for amp rating identification, with this 1A variant featuring yellow and green color bands.
