Eaton FNQ-3-2/10 Fuse - Time-Delay CE RoHS Compliant
Part Number: FNQ-3-2/10
Quick Summary
FNQ-3-2/10 fuse provides time-delay protection for motor circuits in automation panels. Engineers often face nuisance trips when motors start or when circuits endure inrush currents, which can drive unnecessary downtime. This Bussmann series fuse is CE marked and RoHS compliant, offering reliable interruption at 500 V with a 10 kAIC rating, while its ferrule-end connections simplify harnessing in compact enclosures. The 3.2 A rating targets small to medium control circuits without sacrificing safety. In practice, it supports cost-effective protection for drives, relays, and transformers. With standard packaging and a non-indicating fuse indicator, technicians can stock and install quickly, reducing downtime and procurement complexity across industrial facilities.

FNQ-3-2/10~FNQ-3-2-10~BUSS MIDGET FUSE
Time-Delay Protection → Reduces nuisance tripping during motor startup and inrush surges, improving line uptime and process continuity for automation panels. Applications include motor control centers and control cabinets where reliable start-up is critical. 3.2 A rating → Provides precise protection for small drive circuits while avoiding overkill that can increase equipment costs. Result: lower maintenance costs and extended component life in automation loops. High interrupt rating → 10 kAIC at 500 V ensures rapid fault clearing without cascading failures, safeguarding wiring and downstream devices in harsh industrial environments. This translates to improved safety margins and reduced risk of collateral damage in your electrical distribution. Ferrule-end connections → Simple, robust installation in tight spaces; compatible with standard wire ferrules for quick field termination in panel assemblies. Nickel-plated bronze endcaps → Enhanced durability and corrosion resistance for long-term reliability in harsh production environments.

FAQs
For FNQ-3-2/10 installations, use ferrule-end connections to ensure secure terminations in tight panel spaces. Confirm the fuse orientation and ensure the device fits within the 0.41 in by 0.41 in cross-section and 1.5 in height. With non-indicating status, rely on panel indicators and routine electrical checks to verify operation. Always follow manufacturer guidelines and local codes when mounting in Bussmann series compatible enclosures.
Yes. The FNQ-3-2/10 is a time-delay (slow-blow) fuse designed to tolerate brief inrush surges typical of motor starters and transformers. Its 3.2 A rating and 10 kAIC interrupt capability at 500 VAC provide reliable protection without nuisance trips during start-up, making it appropriate for automation equipment and control panels subject to transient currents.
This fuse is CE Marked and RoHS Compliant, aligning with European regulatory standards and low-toxicity material requirements. These certifications help streamline regulatory approvals for machinery and panel builds, enabling smoother integration into compliant industrial systems and reducing compliance risk in global supply chains.
FNQ-3-2/10 measures 0.41 in by 0.41 in with a height of 1.5 in. It uses ferrule-end x ferrule-end connections, which facilitate quick, reliable termination in standard control cabinets. The compact size supports dense panel layouts and retrofit projects, while nickel-plated bronze endcaps provide durability in industrial environments.
Using FNQ-3-2/10 delivers measurable ROI through reduced downtime from nuisance trips, improved uptime for motor-driven processes, and safer fault isolation with a 10 kAIC interrupt rating. Its CE RoHS compliance simplifies procurement and regulatory alignment, while standard packaging and compatibility with the Bussmann series streamline stocking and replacement in large-scale automation deployments.
