Yes, it is rated to the NEMA 12 family of JIC and small panels, so it is the correct interior panel for a dust-tight, drip-tight industrial enclosure of that size. Keep in mind the panel itself is an interior mounting plate, not a sealing component, so the enclosure gasket and door latch are what hold the NEMA 12 rating.

Both. It is a stainless steel panel with a white powder coat finish. The white coating gives you contrast for marking out DIN rail and device layout, and stainless underneath is what you want in washdown, food processing, or corrosive areas where a plain galvanized panel would rust at the drill points.

On JIC and small enclosures the back panel is normally a separate line item, and the AW1412SP is that item, ordered as an accessory to the box. You still supply your own mounting hardware if the enclosure did not ship with collar studs and nuts, plus whatever DIN rail or wire duct you screw to the face of the panel.

Order Eaton B-Line part number AW1412SP. That is the stainless, white powder coated sub-panel sized 12.87 by 10.87 inches for 14 x 12 JIC enclosures.

It weighs 2.975 lb, so it is a one-hand lift. You can set it on the studs and start the nuts without a second person, which matters when the enclosure is already hung on a wall or a machine frame.

Yes. A JIC sub-panel like the AW1412SP is meant to be drilled, tapped, and laid out for contactors, terminal blocks, DIN rail, and duct before it goes in the box. Working it on the bench and then dropping the finished assembly into the enclosure is the normal sequence. Touch up any bare drill edges if the panel is going into a wet or corrosive area.
