The AF64SDW is a panel board front trim from the AF series, sized 64.500 in high by 30 in wide, surface-mounted, and enclosed in a NEMA 1 rating — meaning it's a general-purpose indoor enclosure that protects against incidental contact and falling dirt, but is not sealed against moisture or dust.
Surface mounting means the box and trim assembly fastens directly to a wall or structural support — no flush-in-wall cutout required. The front trim is hinged to the box, giving swing-open access to the interior for breaker or bus installation.
