FNA-2-1/2 Description

Short technical summary and product information.

The FNA-2-1/2 is a cartridge fuse manufactured by Eaton - Bussmann Electrical Division. It is rated for 2.5A at 250VAC with a slow blow response time, making it suitable for applications requiring tolerance of inrush currents. The fuse has a breaking capacity of 200A at rated voltage and includes an alarm indicating feature to signal a blown fuse.

 

This fuse is packaged in a cylindrical, alarm indicating 5AG case measuring 10x38.1mm (0.406" diameter x 1.500" length). It requires a holder for mounting, typical of 5AG cartridge fuses. The design is intended for electrical and industrial overcurrent protection applications.

 

The fuse carries approvals from CE, CSA, and UL, ensuring compliance with international standards. The alarm indicating feature provides visual or remote indication when the fuse opens, aiding in maintenance and troubleshooting.
