Eaton FNQ-1/8 Fuse - 500 V, 10 kAIC, CE Marked
Part Number: FNQ-1/8
Quick Summary
Eaton FNQ-1/8 fuse is a time-delay device designed for motor control circuits facing inrush currents. In busy panels, nuisance trips during start-up drive downtime and maintenance costs. It carries CE marking for European safety compliance, with rugged nickel-plated bronze endcaps that withstand harsh industrial environments. The ferrule-end connections enable quick, reliable terminations, while the 500 V rating and 10 kAIC interrupt capability provide robust protection for demanding loads. Common use cases include motor control transformers and circuits with inrush currents in automation lines, conveyors, and panel installations. This combination supports faster commissioning and reduces the risk of nuisance trips in high-demand sectors such as packaging, material handling, and process automation.

FNQ-1/8~FNQ-1-8~BUSS MIDGET FUSE
Time-delay design reduces nuisance trips in motor start-up, delivering steadier protection and improved uptime. In busy industrial environments, brief surges are tolerated, preventing unplanned downtime and costly maintenance. This feature is ideal for motor control circuits, transformers, conveyors, and automation panels where start-up surges occur regularly. Precise electrical ratings—0.125 A, 500 V, 10 kAIC interrupt rating—balance protection with reliability, enabling fast fault clearing while safeguarding sensitive control circuits. Applications include low-current control logic, auxiliary circuits, and panel-mounted protection where a small fuse is required to maintain system availability. Ferrule end x ferrule end connections simplify installation, reducing crimping time and ensuring consistent terminations across production lines. Nickel-plated bronze endcaps offer durability and corrosion resistance in harsh environments, extending service life in metal processing, packaging, and automation settings. CE Marked packaging provides regulatory clarity and easy stocking for European projects, while non-indicating status helps avoid misinterpretation in crowded panels.

FAQs
Power must be off before work begins. Use ferrule-end terminations to connect the fuse into the designated control circuit, ensuring clean, straight crimps and proper seating. Confirm the 0.125 A rating matches the protected circuit, then secure the fuse in its holder. Avoid bending the fuse or applying excessive force to the endcaps to maintain reliability.
The FNQ-1/8 delivers a time-delay protection profile that tolerates brief startup surges, reducing nuisance trips. With a 0.125 A rating, 500 V operating voltage, and 10 kAIC interrupt capability, it reliably protects low-current control circuits without sacrificing rapid fault clearance. This balance is ideal for motor starters, control logic power, and small transformers in automation setups.
Yes, the FNQ-1/8 fuse is CE marked, signaling compliance with European safety standards for electrical equipment. The specification confirms suitability for European panel builders and integrators. There is no documented indication of other certifications in the provided data, so rely on CE conformity for regulatory alignment in corresponding markets.
Absolutely. The FNQ-1/8 features ferrule end x ferrule end connections, aligning with Bussmann FNQ series compatibility. This simplifies retrofits and new builds, enabling rapid integration into standard control cabinets and harnesses without custom connectors or adapters. This compatibility helps maintain consistent protection across an entire automation line.
By tolerating inrush surges, the FNQ-1/8 minimizes unplanned downtime, reducing maintenance costs associated with nuisance trips. The robust construction (nickel-plated endcaps, 500 V rating, 10 kAIC) extends service life in harsh environments, lowering replacement frequency and spare part inventory. Overall, expect improved line uptime and predictable protection for motor control circuits.
