Eaton FNQ-1-6/10 Fuse - 10 kAIC at 500 Vac
Part Number: FNQ-1-6/10
Quick Summary
The Eaton FNQ-1-6/10 fuse provides time-delay protection for motor control circuits in industrial equipment. Inrush currents and nuisance trips can drive maintenance costs and downtime unless protection is paired with appropriate delay. CE marking and RoHS compliance support global deployments, while the 10 kAIC interrupt rating ensures fast fault clearing across 500 V systems. Together with its nickel-plated bronze endcaps and ferrule-end connections, it integrates with standard panels while delivering measurable reliability. Professionals appreciate the compact form factor, with a 1.5 in length and ferrule-end connections for quick field replacement and lower installation labor. For engineers designing motor starters, drives, and transformers, FNQ-1-6/10 provides a familiar, standards-based protection solution that reduces risk in critical applications. Overall, this fuse helps meet reliability targets and support uptime across international facilities.

FAQs
FNQ-1-6/10 is designed for motor control circuits, transformers, and other equipment that experience startup surges. It fits in standard protection panels using ferrule-end terminations, with a compact 1.5 in body length and standard packaging for easy retrofits. Engineers typically pair this fuse with contactors and overload devices to balance protection and uptime.
Interrupt rating of FNQ-1-6/10 is 10 kAIC at 500 Vac, providing ample margin for fault isolation in high-inrush applications. This specification ensures fast clearing of faults while protecting downstream devices such as drives and transformers, reducing the likelihood of cascading failures. In practice, the rating supports panel builders seeking robust protection in mid-size industrial systems.
Yes. The FNQ-1-6/10 is CE marked and RoHS compliant, aligning with European and global regulatory requirements. These certifications help ensure traceability, safe materials, and minimized hazardous substance exposure in assembled equipment. For OEMs and integrators, this reduces compliance risk when shipping to multi-region installations and simplifies supplier qualification processes globally.
It uses a controlled delay to tolerate brief startup surges while still interrupting sustained faults. In motor and transformer circuits, the delay prevents nuisance trips during normal acceleration, while the fuse remains responsive to actual fault conditions beyond the inrush. This balanced behavior helps maintain uptime and protects downstream devices.
Select ferrule-end terminations that match panel cables and use clean ferrule pins to avoid loose connections. Ensure proper mounting with standard packaging and verify the 500 V rating suits your system; keep breakers and fuses within the 1.6 A rating to avoid nuisance trips. Regular inspection of nickel-plated bronze endcaps helps prevent corrosion in harsh environments.
