Eaton FNA-8 Fuse - 10 kAIC at 125 Vac - Dual-Element
Part Number: FNA-8
Quick Summary
Eaton Bussmann series FNA fuse provides time-delay protection for inductive and electronic circuits in industrial controls. To design reliable panels, engineers need a fuse that withstands inrush without sacrificing protection during fault conditions. This device delivers dual-element construction with an 8 A rating and 10 kAIC interrupt capability at 125 V, supporting both motor start-up and electronic load scenarios. The fuse features ferrule-end connections and silver-plated pins for secure wiring and low contact resistance. CE Marked compliance confirms EU safety and performance standards, while rugged packaging and standard sizing simplify stocking and replacement. By selecting this fuse, manufacturers can reduce nuisance trips, improve uptime, and lower maintenance costs across automation and electrical protection applications.

FAQs
Install the FNA-8 with ferrule-end x ferrule-end connections using wires sized for 8 A at 125 V. Ensure proper seating of the silver-plated pins for low contact resistance, and verify the circuit is de-energized before replacement. The non-indicating design simplifies visual inspection, while the ferrule ends reduce wiring strain and improve connector longevity in panel assemblies.
The FNA-8 is an 8 A time-delay, dual-element fuse with a 10 kAIC interrupt rating at 125 Vac. It is suitable for inductive loads and electronic circuits, including motor start-up and panel control applications where inrush is common. Its 125 V rating and CE compliance make it appropriate for European and international machinery and automation projects.
Yes. The time-delay (dual-element) design accommodates inrush currents typical of motors and other inductive loads without nuisance tripping, while still providing fast protection during faults. With an 8 A rating and 10 kAIC interrupt capability at 125 V, it guards both motor starters and sensitive electronic loads in control panels and automation equipment.
The FNA-8 is CE Marked, indicating compliance with EU safety standards. This helps with regulatory approvals and customer qualification processes in Europe and other markets that recognize CE compliance for electrical protection components.
The time-delay, dual-element construction reduces nuisance trips during startup and cycling, lowering unplanned downtime. Its robust 10 kAIC interrupt rating at 125 V supports reliable protection for motors and electronics, improving equipment uptime and extending the mean time between failures. Standard packaging and ferrule-end connections also reduce maintenance time and inventory complexity.
