Eaton FNQ-R-1-1/4 Fuse - Class CC, 200 kAIC
Part Number: FNQ-R-1-1/4
Quick Summary
The Eaton FNQ-R-1-1/4 fuse is a time-delay, current-limiting protection device designed for line protection and small-control circuits. Finding a fuse that withstands inrush currents while guarding critical electrical panels in compact control environments can be challenging. Two key certifications—CE Mark and RoHS compliant—support regulatory alignment for regional and global deployments, while its 200 kAIC interrupt rating at 600 V adds robustness for fault scenarios. Beyond compliance, the FNQ-R’s Class CC construction, ferrule-end connections, and current-limiting behavior deliver reliable protection with a compact footprint, reducing panel size and maintenance needs. This makes it a strong fit for line protection, small transformers, and branch circuits in industrial control panels, delivering ongoing uptime and safety.
