B-Line Eaton series wall mounted panel enclosure, 48" height, 12" length, 36" width, 4, Hinged cover, 43PT enclosure, Wall mount, Medium single door,

It carries a NEMA 4 rating, which covers indoor and outdoor use against windblown dust, rain, splashing water and hose-directed water. The seal comes from a seamless poured in-place gasket on the hinged cover, and the box is UL 50 listed. NEMA 4 does not include corrosive-atmosphere protection; the shell here is painted carbon steel, so for caustic or salt exposure you want a stainless or nonmetallic 4X box instead.

Outside dimensions are 48 inches high, 36 inches wide and 12 inches deep. That 12 inch depth is the usable back-to-front space less the door and gasket flange, so plan your panel, wireway and breaker projection inside it. A back panel or subpanel is a separate order item; the enclosure ships as the box with the hinged door.

It weighs 127.2 lb empty and mounts with external mounting feet, so the fasteners land outside the sealed enclosure and you never breach the NEMA 4 envelope to hang it. At that weight, with panel and devices on top of it, anchor into studs, masonry or a welded strut frame, not into drywall. Two people for the lift.

Yes. The door uses a 3-point latching handle with key lock and padlock provision, so you can lock it with the supplied key arrangement or drop a padlock through the provision for lockout-tagout. The 3-point latch pulls the door tight at top, middle and bottom, which is what keeps the gasket compressed evenly across a 48 inch tall door.

Body and door are 14 gauge carbon steel, painted ANSI 61 grey. Fourteen gauge is the usual commercial weight for medium single door industrial enclosures of this size and handles wall-mounted control gear and door-mounted pilot devices without oil-canning. If you are cutting large window or HMI openings in the door, keep them centered to preserve the stiffness the 3-point latch relies on.

It is a hinged door enclosure, not a screw cover. The door swings on its hinge and secures with the 3-point handle, so you get one-hand access for service without setting loose cover screws on the floor. Screw-cover NEMA 4 boxes seal the same way but have to come off entirely, which is why hinged is the usual pick anywhere the panel gets opened more than at commissioning.

NEMA 4 enclosures of this type ship with no knockouts, because any factory opening would break the watertight rating. You drill or punch your own entries on site and seal them with NEMA 4 rated hubs or liquidtight fittings. Keep penetrations on the bottom or sides where practical so water is not sitting over a fitting.

The finish is painted ANSI 61 grey, the standard light grey used across most industrial control panels and switchgear, so it lines up visually with existing B-Line, Hoffman and comparable gear finished to the same spec. Handy when you are adding a panel to a wall that already has a row of them.
