Eaton Specification Sheet - FNA-3-2/10
Time-delay, dual-element construction absorbs inrush currents common with motors and transformers, reducing nuisance trips and extending fuse life in demanding applications. This translates to smoother starts, fewer unscheduled outages, and lower maintenance costs in motor control centers and power supplies. The design is well-suited for inductive loads and electronic circuits, improving reliability where short surges occur. High interrupt ratings of 10 kAIC at 125 Vac and 200 kAIC at 250 Vac provide robust protection against short circuits, minimizing fault propagation and equipment downtime in panel boards and manufacturing lines. CE Marked and RoHS compliant, the device helps procurement and compliance teams meet regulatory requirements without compromising performance. Its compact ferrule-end connection, silver-plated pins, and standard packaging enable quick replacement, even in tight spaces, while the non-indicating status pairs with system-level monitoring to keep panel layouts clean and maintenance straightforward. The fuse’s dual-element construction also supports superior overload and cycling capabilities, delivering long-term protection across evolving industrial loads.

FAQs
The FNA-3-2/10 is a ferrule-end, dual-element time-delay fuse designed for standard panel installations. It fits equipment with ferrule-end connections and standard Bussmann series form factors, supporting inductive loads and electronic circuits across industrial control panels. Its compact 0.35 in by 0.35 in footprint assists in crowded enclosures, and the silver-plated pins offer reliable contact under vibration.
Its time-delay, dual-element design tolerates brief inrush currents common with motors, transformers, and other inductive loads. This reduces nuisance trips and extends fuse life, which translates into fewer maintenance interventions and more consistent equipment uptime in applications like motor starters and power supplies.
Yes. The FNA-3-2/10 is CE Marked and RoHS Compliant, aligning with European regulatory requirements and global procurement standards. This simplifies international sourcing, audits, and deployment across multi-region facilities without sacrificing performance or protection levels.
The fuse provides a 3.2 A rating at 250 V, with interrupt ratings of 10 kAIC at 125 Vac and 200 kAIC at 250 Vac. These ratings offer substantial protection margins for industrial panels and power paths, helping to prevent short-circuit damage or cascading outages in critical systems.
The time-delay dual-element design reduces nuisance trips during inrush, lowering unplanned downtime and extending cycle life. Durable ferrule-end connections and silver-plated pins improve contact reliability, enabling longer intervals between replacements. Overall, these factors contribute to lower maintenance costs and a favorable return on investment in automated manufacturing environments.
