FNQ-1/4 Description

Short technical summary and product information.

The Eaton Bussmann FNQ-1/4 is a 250mA, 600VAC cartridge fuse designed for industrial and electrical applications. It features a slow blow response time to handle transient inrush currents without nuisance opening.

 

This fuse provides a high breaking capacity of 200kA at rated voltage, making it suitable for high-fault-current circuits. It is rated as Class CC and carries approvals from CE, CSA, and UL.

 

The fuse is housed in a 5AG package (10.3mm diameter x 38.1mm length) and requires a compatible fuse holder for installation. Its physical dimensions match the standard North American midget fuse footprint.
