Eaton Specification Sheet - FNA-2-1/2
Time-delay performance protects power systems from nuisance trips during motor start-up and inrush events, reducing unplanned outages and maintenance time. This translates to improved line uptime and lower total cost of ownership for control panels and industrial circuitry. The 2.5 A rating provides precise protection for small-control electronic loads, while maintaining safe operation across standard European mains. High interrupt ratings of 10 kAIC at 125 Vac and 200 kAIC at 250 Vac deliver strong short-circuit protection in distribution feeders and motor circuits, preventing equipment damage and costly downtime. The dual-element design enhances overload tolerance and cycling capability, supporting longer fuse life in demanding duty cycles. Ferrule-end connections simplify panel wiring and field replacement, offering consistent terminations and dependable contact reliability with silver-plated pins for corrosion resistance. Non-indicating indicators keep cost down and maintenance straightforward, while standard packaging ensures easy stocking and compatibility with existing inventory. Overall, these fuses are designed to meet stringent reliability requirements in industrial automation environments, delivering measurable improvements in protection performance, service life, and maintenance efficiency.

FAQs
The FNA-2-1/2 fuse is designed for inductive and electronic circuits in electrical protection and control panels. It uses ferrule-end terminations for easy integration with standard panel wiring and accepts dual-element construction to handle startup surges in motors and similar inductive loads.
Key ratings are 2.5 A amperage, 250 V voltage, and interrupt ratings of 10 kAIC at 125 Vac and 200 kAIC at 250 Vac. These indicate the fuse can safely interrupt high-energy fault currents and protect circuits without nuisance trips during normal operation, enabling reliable protection for small-control electronics and inductive loads.
Yes. The time-delay (dual-element) design accommodates inrush and cycling typical of inductive loads, reducing nuisance tripping while providing rapid fault interruption when faults occur. This makes it well-suited for motor starters, solenoids, and other inductive circuits in automation equipment.
The FNA-2-1/2 is CE Marked, indicating conformity with European safety standards. This helps ensure regulatory compliance for European installations and simplifies procurement in markets that require CE certification for electrical protection devices.
With a dual-element construction and high interrupt ratings, the fuse offers reliable protection and extended cycling capability, reducing maintenance intervals and prolonging panel life. Non-indicating design keeps initial costs down, while ferrule-end connections enable straightforward replacement and consistent terminations, contributing to lower lifecycle costs and improved uptime in automation systems.
