Bussmann FNA-1 Fuse

FNA-1 is a Bussmann FuseTron midget time-delay fuse rated 1 A at 125 V AC, designed to protect small electronic circuits while tolerating brief inrush currents. The compact 13/32 in x 1-1/2 in body uses ferrule end terminations for secure insertion into common fuse holders. It features a pin-indicating design that visually shows when the fuse has opened. Electrical interrupting ratings include 10 kAIC at 125 VAC and 200 kAIC at 250 VAC. The FNA-1 is intended for time-delay protection in inductive loads and other circuits where brief overloads are expected. Color coding and designation: green color-code for the 1 A rating, helping quick identification in panel boards and equipment. This part is part of the Bussmann FNA series and is supplied by Eaton as part of the FuseTron lineup, optimized for control and small-power circuits where reliable, slow-blow protection is needed.
