FNQ-12 Description

Short technical summary and product information.

The FNQ-12 is a cartridge fuse manufactured by Eaton's Bussmann Electrical Division. It is rated for 12A continuous current at 500VAC with a slow blow response time, making it suitable for applications with inrush currents. The fuse offers a breaking capacity of 10kA at rated voltage, providing robust overcurrent protection.

 

This fuse uses a 5AG (10mm x 38mm) package size, also known as a midget fuse, and requires a holder for mounting. Its physical dimensions are 0.406 inches diameter by 1.500 inches length (10.30mm x 38.10mm). The FNQ-12 is designed for electrical and industrial applications, including motor circuits, power supplies, and control panels.

 

The fuse carries approvals from CE, CSA, and UL, indicating compliance with relevant safety standards. Note that RoHS, REACH, and MSL compliance statuses are unverified and should be confirmed with the manufacturer.
