FNQ-R-30 FUSE

Description

The FNQ-R-30 is a dual-element, current-limiting, time-delay fuse from the Eaton Bussmann FNQ-R series. It is designed to protect control circuits, small transformers, and industrial branch circuits while allowing normal inrush currents without nuisance tripping.

This fuse uses a rejection-style Class CC design, ensuring it only fits compatible fuse holders, improving safety by preventing incorrect replacements.
