FNQ-R-4/10 FUSE

Description

The FNQ-R-4/10 is a rejection-type, current-limiting, dual-element fuse from the Eaton Bussmann FNQ-R series. It is engineered to provide reliable protection against overloads and short circuits while allowing normal inrush currents from transformers and control loads without nuisance blowing.

This fuse is widely used in industrial automation panels, PLC systems, control transformers, and branch control circuits where high interrupting capacity and precise coordination are required.
