Eaton FNM-2 Fuse - Time-delay 2A, CE Marked for Protection
Part Number: FNM-2
Quick Summary
The Eaton FNM-2 fuse provides reliable time-delay overcurrent protection for control panels and industrial equipment. Nuisance tripping during motor starts and frequent cycling can drive unplanned downtime and maintenance costs. CE Marked compliance aligns with European safety standards, and the device is rated for 250 V systems. With a 2 A amperage and an interrupt rating of 100 AIC at 250 Vac (and 10 kAIC at 125 Vac), it protects conductors while tolerating inrush. Its nickel-plated bronze endcaps and ferrule-end terminations simplify installation in modern control cabinets, delivering predictable performance and extended asset life. This makes it a practical choice for automation projects seeking reliable protection with easy serviceability.

FNM-2~BUSS MIDGET FUSE
Datasheet - FNQ-30
Time-delay operation provides controlled response to inrush currents, reducing nuisance trips during motor starts in conveyors and automated panels. This translates to measurable uptime gains and lower maintenance costs in demanding environments. Use the FNM-2 in motor drives, automation controllers, and heater circuits where brief surges are expected, and dependable protection is critical for production continuity. With a 2 A amperage rating and high interrupt ratings, it safely interrupts fault currents while tolerating startup surges. The 100 AIC at 250 Vac rating protects power feeds in standard European-style control cabinets, while the 10 kAIC at 125 Vac supports mixed-voltage assets. This enables reliable protection where feeders experience brief inrush or short transients. End connections are ferrule end x ferrule end, with nickel-plated bronze endcaps delivering secure, corrosion-resistant terminations in tight panels. The compact Bussmann midget fuse footprint fits standard protection layouts, allowing quick swaps during maintenance without rewiring. Non-indicating design keeps panel aesthetics clean while operators rely on planned replacement intervals for predictable uptime. CE Marked compliance and a 250 V rating ensure the FNM-2 aligns with European electrical safety requirements, simplifying procurement and spec alignment for mixed-site deployments. Standard packaging and ferrule terminations support quick stocking, qualification testing, and straightforward integration into new or retrofit projects across panels and enclosures. Special features include superior overload and cycling capabilities, enabling repeated protection cycles in challenging environments. The non-indicating, dual-element construction reduces signal interference in control architectures while providing precise discrimination with other fuses in the Bussmann family. For technicians and engineers, this translates to lower lifecycle costs and more predictable equipment performance under load transients. Compatibility and maintenance philosophy: as part of the Bussmann series line, the FNM-2 shares footprint and characteristics with similar fuses, enabling multi-sku panel protection with minimal rework. Installers appreciate ferrule-end wiring compatibility and the robust nickel-plated endcaps that resist oxidation in humid environments. When replacement is needed, the standard 0.39 inch length and 1.44 inch height support simple substitution in existing assemblies, reducing downtime.

FAQs
Install the FNM-2 by inserting it into a compatible panel with ferrule-end terminations. The fuse uses nickel-plated bronze endcaps and a dual-element construction for reliable cycling. Ensure proper enclosure clearance and follow standard safety practices for live-term connections. Check the 0.39 in depth and 1.44 in height to confirm fit in tight control cabinets.
At 250 Vac, the FNM-2 provides an interrupt rating of 100 AIC, protecting feeders from short-circuit faults while allowing normal inrush during startup. At 125 Vac, it offers 10 kAIC. The 2 A amperage rating is suited to small control circuits and sensor networks within automation panels.
Best suited for control cabinets, small motor circuits, and heater loads in automation lines, the FNM-2 handles brief surges without nuisance trips. Its time-delay action supports motor startups, drives, and PLC power rails, reducing downtime and extending equipment life. This fuse complements the Bussmann series for consistent protection across panel-based systems.
Yes, the FNM-2 is CE marked, reflecting compliance with European safety requirements for electrical protection devices. It is rated for 250 V and designed to meet typical panel protection standards in European and other CE-regulated markets. For projects requiring additional certifications, verify site-specific requirements and cross-check with Eaton specification sheets.
Termination is ferrule end x ferrule end with nickel-plated bronze endcaps, supporting robust connections in control panels. The fuse is a compact dual-element device with dimensions approximately 0.39 in length and width and about 1.44 in in height, packaged standard. The assembly weighs roughly 0.2 lb and uses standard Bussmann-series form factors for quick stocking and replacement in existing layouts.
