FNA-3 Description

Short technical summary and product information.

The FNA-3 is a cartridge fuse manufactured by Eaton - Bussmann Electrical Division. It is rated for 3A continuous current at 250VAC, with a slow-blow response characteristic suitable for handling inrush currents. The fuse has a breaking capacity of 200A at rated voltage, ensuring safe interruption of overcurrents.

 

The fuse is housed in a cylindrical, alarm indicating package of 5AG size (10x38.1mm). It requires a holder for mounting, and the alarm indicator provides visual indication when the fuse has opened. This feature is useful for quick identification of blown fuses in industrial applications.

 

The FNA-3 is designed for electrical and industrial applications and carries approvals from CE, CSA, and UL, indicating compliance with relevant safety standards.
