The AF55FN is a panel board front trim from the A Series, sized 55-1/2" x 20" with a flush mounting style and NEMA 1 rating. It includes a nameplate and is designed for indoor panel installations where a flush appearance and basic environmental protection are required.
At 20 inches wide, the AF55FN fits panel cutouts designed for a 55-1/2" tall by 20" wide flush-mounted front trim. The NEMA 1 rating means it is suitable for indoor use where drip-free, non-corrosive conditions exist — typical for electrical rooms and light industrial enclosures. The flush mount sits the trim flush with the surrounding wall or panel surface, giving a clean finished look.
