Eaton FNM-3-2/10 Fuse - 100 AIC at 250 Vac, Dual-Element
Part Number: FNM-3-2/10
Quick Summary
The Eaton FNM-3-2/10 fuse is a time-delay device that protects small-control circuits and drive loads in compact electrical panels. Engineers often contend with nuisance trips from inrush currents and transient cycling, which this fuse mitigates through its dual-element design. It carries CE marking and RoHS compliance, and its nickel-plated bronze endcaps offer durable, long-life performance in industrial environments. For OEMs and panel builders, the ferrule-end connections and compact footprint simplify installation while helping to minimize inventory and maintenance costs. This combination of performance, reliability, and regulatory alignment translates to improved uptime and safer electrical protection in automation and motor-control applications.

Time-delay operation enables the FNM-3-2/10 to withstand inrush currents and short transients, reducing nuisance trips in motor starters and solenoids while preserving circuit protection. Business impact: increased equipment uptime and reduced maintenance calls in automation equipment and control panels. Application: ideal for conveyor drives and small drive assemblies where startup spikes are common. The fuse’s 3.2 A rating paired with a 100 AIC at 250 Vac and 10 kAIC at 125 Vac delivers fast, predictable fault clearing, protecting wiring and components without sacrificing normal operation. This supports safer panel conditioning and extended component life in automation systems. Dual-element design provides robust cycling performance, lowering replacement frequency in environments with repetitive switching. Application notes: suitable for control circuits and relay-based protection schemes, with improved life under frequent switching. Ferrule-end x ferrule-end connections and nickel-plated bronze endcaps enhance durability in harsh environments, reducing maintenance and corrosion-related failures. The standard packaging and compact size fit tightly packed control panels and switchgear without bulky hardware, enabling streamlined installation and stocking. Compliance with CE and RoHS standards further ensures regulatory alignment and vendor confidence across global deployments.

FAQs
Yes. The fuse uses ferrule end x ferrule end connections with nickel-plated bronze endcaps, designed for standard ferrule terminals commonly found in compact control panels. Its dimensions (0.39 in width and depth, 1.44 in height) and standard packaging simplify mounting in space-constrained panels, while its 250 V rating aligns with typical control circuits. This reduces the need for special adaptors and supports fast, reliable field installs.
You can expect reliable protection against short circuits with a 100 AIC interrupt rating at 250 Vac and 10 kAIC at 125 Vac, along with a 3.2 A amperage rating. The time-delay characteristic minimizes nuisance trips during motor start-up and is well-suited for small drive and relay-activated circuits. This combination improves uptime and protects control wiring without compromising normal operation.
Yes. The FNM-3-2/10 is CE marked and RoHS compliant, ensuring conformity with European safety and environmental standards. While it carries these certifications, always verify regional requirements for your specific installation, as additional approvals may apply depending on end-use and industry.
The dual-element design provides improved tolerance to frequent cycling and transient overloads, reducing premature failures in rapidly switching control circuits. This translates to fewer replacements and less downtime in automation equipment, especially in applications with frequent on/off cycling like conveyors, feeders, and relay-driven panels.
The fuse’s durable nickel-plated endcaps, ferrule-end connections, and compact 0.39 x 0.39 in footprint contribute to lower maintenance and easier stocking. Standard packaging simplifies inventory management, while robust electrical protection reduces unplanned downtime and extends the life of downstream components, delivering a lower total cost of ownership in motor-control and panel-building applications.
