Eaton BK/FNQ-R-1/4 Fuse - Class CC Time-Delay, 200 kAIC @ 600 Vac
Part Number: BK/FNQ-R-1/4
Quick Summary
The Eaton BK/FNQ-R-1/4 fuse provides current-limiting time-delay protection for control panels and small motor circuits. In busy automation environments, nuisance tripping and undersized protection can interrupt production and increase maintenance costs. This FNQ-R series device is CE marked for European safety compliance and features ferrule-end terminations for secure, field-proven connections. With a 0.25 A rating, Class CC construction, and a high 200 kAIC interrupt rating at 600 Vac, it is well-suited to modern 600 V systems. For procurement efficiency and reliable uptime, its bulk packaging and Bussmann lineage offer familiar form factor and predictable performance across critical automation applications.

FAQs
BK/FNQ-R-1/4 uses ferrule end x ferrule end terminations, rated for 600 V. It performs with a 0.25 A amperage rating and a 200 kAIC interrupt capacity, making it suitable for 600 V control circuits and panel protection in industrial environments.
The fuse is a current-limiting time-delay device with a 0.25 A rating, Class CC form factor, and a 12-second response at 200% overload. It also offers a high interrupt rating of 200 kAIC at 600 Vac, ensuring fast fault clearance while accommodating normal inrush in control circuits.
Yes. Its current-limiting, time-delay characteristics are designed for panel protection and automation circuits. The ferrule terminations provide secure wiring, and the bulk packaging supports OEM and panel-builder needs for scalable installations in 600 V systems.
The data indicates CE marking for compliance with European safety standards, supporting regulatory requirements for European markets. No additional certifications are listed in the provided specifications.
Plan for ferrule-end terminations in standard Bussmann-series form factors, with bulk packaging to reduce stocking costs. The 600 V rating and 0.25 A rating suit discrete protection in control panels, and the high interrupt rating helps with future-proofing against possible fault currents.
