FAQs
Install the FNA-7 with ferrule-end terminations for a secure, vibration-resistant connection. Verify 125 V operating supply and 7 A rating, then insert into the appropriate slot or fuse holder. Tighten ferrule terminals to specification, and use standard wiring practices. For monitoring, consider external indicators since the device is non-indicating.
The FNA-7 features a time-delay, dual-element design that tolerates motor inrush and rapid cycling without nuisance trips. Its 10 kAIC interrupt rating at 125 V provides robust short-circuit protection, while the 7 A rating suits medium-current inductive circuits found in control panels and equipment starters.
Yes. The 7 A rating, 125 V operation, and time-delay characteristic make it well-suited for motor starters and small motors in control panels. The high interrupt rating helps withstand inductive surges, reducing counter-trips, while Ferrule-end connections streamline panel wiring and retrofit projects.
The FNA-7 is CE Marked, indicating conformity with European safety standards. Additional certification details and compliance data are available in Eaton’s datasheets and the Bussmann catalog, which include the full range of electrical protection and circuit-control features for this fuse family.
Because the fuse is non-indicating, plan for periodic electrical field checks or remote monitoring to verify status. The time-delay dual-element design reduces nuisance trips, lowering maintenance costs and downtime. Standard ferrule-term connections simplify replacements, supporting lower total cost of ownership in ongoing protection of automation assets.
