The AF64SNW is a Siemens A Series panel board front trim, sized at 64.500 in tall by 30 in wide, designed for surface mounting with a NEMA 1 enclosure rating and an included nameplate.
The NEMA 1 rating means this trim is intended for indoor use where the equipment is protected from falling dirt and light indirect splashing — typical for a clean electrical room or a dry panel shop floor. Surface mounting keeps the install straightforward: the trim fastens directly to the panel board enclosure without a flush-mount subframe. The 30 in width and 64.500 in height match the standard A Series panel board footprint, so it aligns with the existing enclosure cutout and gutter space — no field modification needed to fit the trim to the box.
