Overview
The Bussmann FNM-1-6/10 is a Fusetron series midget supplemental fuse engineered for time-delay protection of 125/250 VAC inductive circuits. This 1.6 A dual-element fuse features ferrule-end-to-ferrule-end terminals, non-indicating design, and nickel-plated bronze endcaps, making it a drop-in replacement for legacy electrical protection systems. The fuse measures 13/32″ × 1-1/2″ with color-coded green for 250V maximum voltage.
