FAQs
The FNM-9 uses ferrule-end connections and a compact dual-element design, making it compatible with standard Bussmann series panel protection layouts. Its 0.39 in by 0.39 in by 1.44 in footprint fits into common DIN rail and enclosure slots, while the nickel-plated bronze endcaps provide durable mounting in vibration-prone environments. Ensure your panel wiring matches ferrule terminations and the 9 A, 250 V rating for proper protection.
The FNM-9 fuse offers an interrupt rating of 10 kAIC at 125 Vac and 200 AIC at 250 Vac. This means it can safely interrupt fault currents up to those levels at the specified voltages. Use this rating to assess protection coordination with upstream breakers and to prevent damage to feeders and devices during short-circuit events.
Yes. The FNM-9 is CE marked and RoHS compliant, signaling conformance to European safety standards and restrictions on hazardous substances. This makes it suitable for international projects, regulatory audits, and manufacturing environments that require compliance documentation and traceability for electrical components.
The time-delay, dual-element design accommodates temporary inrush currents typical of motors and power supplies, preventing nuisance tripping during startup while still providing fast fault clearing. This translates to higher line availability, reduced maintenance interruptions, and improved machine uptime in manufacturing environments where loads surge during startup.
With nickel-plated bronze endcaps and robust ferrule connections, the FNM-9 is designed for durability in vibration-prone or harsh environments. Routine checks should verify endcap integrity, ferrule seating, and enclosure sealing to prevent exposure to contaminants. Its compact profile also simplifies replacement during scheduled PM cycles, minimizing downtime and inventory complexity.
