FNA-3-1/2 Description

Short technical summary and product information.

The FNA-3-1/2 is a cartridge fuse from Eaton Bussmann Electrical Division, designed for overcurrent protection in electrical and industrial applications. It is rated for 3.5A continuous current at 250VAC with a breaking capacity of 200A at rated voltage.

 

The fuse features a slow blow (time-delay) response characteristic, making it suitable for circuits with inrush currents. It includes an alarm indicating function that provides visual or mechanical indication when the fuse has opened.

 

The fuse is housed in a cylindrical 5AG package measuring 10.31mm diameter by 38.10mm length. It requires a separate holder for mounting and is approved by CE, CSA, and UL agencies.
