FNQ-6 Description

Short technical summary and product information.

The Eaton - Bussmann Electrical Division FNQ-6 is a 6A slow-blow cartridge fuse designed for overcurrent protection in electrical and industrial applications. It offers a voltage rating of 500VAC and a breaking capacity of 10kA at rated voltage. The slow-blow (time-delay) characteristic allows it to tolerate temporary inrush currents without nuisance opening, making it suitable for circuits with capacitive or inductive loads.

 

This fuse is housed in a 5AG midget package with dimensions of 10.30mm x 38.10mm (0.406" diameter x 1.500" length) and requires a separate fuse holder for installation. It is approved by CE, CSA, and UL, confirming its compliance with North American and European safety standards. The FNQ-6 is a direct replacement part for many industrial equipment fuse blocks.
