FAQs
Ensure ferrule-end wiring is correctly terminated to the fuse’s ferrule ends and that the panel design accommodates the 0.37 in depth and 1.46 in height. Use standard packaging and verify the 250 V rating aligns with the control circuit, while checking the 5 A amperage to prevent under- or over-protection that could impact circuit performance.
The FNA-5 features a dual-element time-delay design that tolerates short-term inrush and cycling common in motors and solenoids. With a 5 A rating and high interrupt capability (200 kAIC at 250 Vac), it protects against sustained faults while allowing normal startup behavior, reducing nuisance trips and extending component life.
Yes, the FNA-5 carries CE Marking, confirming compliance with EU safety standards. While the data highlights CE, users should still consult Eaton datasheets for any additional regional certifications relevant to specific markets or industries.
Common applications include motor starters, inductive loads, and electronic control circuits within industrial automation panels. The ferrule-end connections and silver-plated pins facilitate reliable, quick wiring, while the 5 A rating provides precise protection for small to medium control circuits.
The FNA-5’s rugged overload and cycling capabilities reduce nuisance tripping and premature fuse replacements, lowering maintenance costs. Its high fault-current protection minimizes downstream damage, leading to longer service intervals and improved machine uptime—crucial factors for overall ROI in automated production lines.
