FNQ-4 TIME DELAY FUSE

Description

The FNQ-4 is a 4A time-delay (slow-blow) supplemental/Class CC fuse from the Eaton Bussmann FNQ series. It is designed for the protection of control transformers, relay circuits, lighting circuits, and meter circuits where temporary inrush currents occur during startup. The time-delay characteristic helps prevent nuisance fuse operation while maintaining reliable overcurrent protection.
