Eaton FNQ-6 Fuse - 10 kAIC @ 500V CE RoHS Compliant
Part Number: FNQ-6
Quick Summary
FNQ-6 fuse provides reliable protection for motor control circuits in industrial panels. Varying inrush currents and nuisance trips can disrupt production, so a time-delay design helps absorb startup surges without sacrificing safety. This fuse is CE marked and RoHS compliant, with a 10 kAIC interrupt rating at 500 V, and it features nickel-plated bronze endcaps for durability in harsh environments. As part of Eaton's Bussmann series, the FNQ-6 offers standard ferrule-to-ferrule terminations and straightforward installation, delivering efficient protection with minimal downtime. By selecting FNQ-6, engineering teams can simplify panel design while maintaining robust regulatory compliance and reliable protection for motor-driven loads.

Feature → Business Impact → Application: Time-delay operation reduces nuisance trips during motor start-up, improving line uptime and equipment longevity in high-inrush applications like conveyors and pumps. This means fewer unplanned outages and lower maintenance costs in manufacturing lines. Feature → Application compatibility → The FNQ-6 uses ferrule end connections for quick field installation, compatible with standard panel wiring practices and widely used control transformers, speeding up commissioning. Feature → High interrupt rating → A 10 kAIC at 500 Vac capability provides strong fault clearance, protecting downstream equipment and reducing the risk of arc flash incidents in electrical cabinets. Feature → Durable construction → Nickel-plated bronze endcaps resist corrosion and blistering in humid or dusty environments, extending service life in harsh industrial settings. Feature → Compliance and labeling → CE Marked and RoHS compliant ensures global regulatory alignment, supporting cross-border product deployment and supplier audits. Feature → Non-indicating status → Non-indicating design reduces cost and panel space, with clear maintenance planning through routine testing and replacement schedules. Feature → 500 V rating → Suitable for general purpose motor control and power electronics in low- to mid-voltage industrial systems, enabling broad applicability without component swaps.

FAQs
The FNQ-6 uses ferrule end x ferrule end connections, a common termination compatible with standard panel wiring. Installation is straightforward in control cabinets and motor starter assemblies, supporting quick field replacements with minimal downtime.
FNQ-6 is rated for 6 A, 500 V with an interrupt rating of 10 kAIC at 500 V. This combination supports robust fault interruption for motor control circuits while tolerating startup inrush currents typical of pumps and conveyors.
Yes. Its time-delay characteristic accommodates startup surges common in motor loads, reducing nuisance trips and enabling smoother operation of drives, transformers, and motor control circuits without compromising protection.
FNQ-6 is CE marked and RoHS compliant, aligning with European regulatory requirements and responsible supplier practices, ensuring suitability for global product deployments and audits.
Because FNQ-6 is non-indicating, schedule periodic replacement based on panel maintenance cycles and fault history. Maintain proper inventory, use compatible ferrule-term fuses, and verify panel integrity to minimize downtime during replacements.
