The AF64SD is a panel board enclosure from the A Series, sized at 64-1/2 inches by 20 inches, designed for surface mounting with a front hinged cover. It carries a NEMA 1 rating, meaning it is intended for indoor use where protection from incidental contact and falling dirt is needed, but not from moisture or dust ingress.
Surface mount configuration — the enclosure is fastened directly to a wall or structural frame. No cutout or flush-mount pocket required. The front hinge allows full access to the interior for terminating conductors or mounting DIN-rail assemblies inside the 20-inch-wide cavity.
