B-Line 363012-4XS3PT Eaton series wall mounted panel enclosure

It carries a NEMA 4X rating, which covers indoor and outdoor duty against hosedown, splashing water, windblown dust and corrosion. The 304 stainless steel body is what earns the X (corrosion resistance), so it suits food processing washdown bays, water treatment, and coastal exterior walls. It is also UL 508A listed for use as an industrial control panel enclosure.

Nominal size is 36 inches high by 30 inches wide by 12 inches deep, which is what the 363012 in the part number refers to. Usable interior is slightly less than that because of the flange and door return, so a full 30 inch wide subpanel will not drop in. Order the matching B-Line subpanel sized for a 36 x 30 enclosure rather than cutting to the outside dimensions.

It weighs 93.9 lb empty, before any subpanel, breakers or controls go in. It mounts by external mounting feet, which keep the back of the enclosure off the wall so water drains behind it rather than pooling. At that weight plan on two people and anchors rated into structure or Unistrut, not drywall anchors.

No. Like other B-Line series wall mount enclosures, the 363012-4XS3PT ships as the enclosure body and door only. The interior subpanel, DIN rail, terminal kits, window kits and any drip shield are separate orders. Budget the subpanel into the job up front, since a 36 x 30 x 12 box is almost always bought to mount controls on.

The 3-point handle drives rods to the top, bottom and latch point of the door, pulling the gasket down evenly across a tall door. On a 36 inch door that even compression is what holds the NEMA 4X seal; single point clamps tend to leave the corners loose on doors this size. The handle also takes a padlock, so the panel can be locked out without adding hardware.

Locking provision is a key lock plus padlock provision on the handle, so you can pad it with your own shackle for LOTO or run the key lock for routine access control. Nothing extra needs to be drilled in the door to lock it.

304 stainless handles most washdown, outdoor and general industrial corrosion. Where it falls short is chloride exposure: marine salt spray, pool chemical rooms, and heavy chlorinated or saline process areas pit 304 over time. For those, specify a 316L stainless version of the same size instead of this 304 enclosure.

None. To hold the NEMA 4X rating the enclosure is supplied unpunched, and the installer cuts entries where the run lands. Every penetration then has to be closed with 4X-rated fittings and hub seals, otherwise the rating is void regardless of what the box is rated for. Bottom or side entry is preferred over the top for that reason.

Body and door are 14 gauge 304 stainless. That is the standard commercial gauge for wall mount control enclosures in this size class and takes a fully loaded subpanel without oil-canning the door, which matters because a flexing door is what breaks a 4X seal.

The stainless is a #4 brushed finish, the standard satin directional grain used in food, pharma and lab spaces because it cleans down easily and does not show wear the way a mirror polish does. Catalog color is listed as grey, which reflects the natural stainless tone rather than paint; there is no painted coating to chip or get eaten in a washdown.

Single hinged door, medium single door style, 36 inches tall on a 30 inch wide box. Since it swings rather than lifting off, leave the full door width of swing clearance to one side plus NEC working space in front, which the mounting feet do not change.

Country of origin is listed as US. Order by manufacturer part number 363012-4XS3PT, Eaton B-Line series, and note that the model designation 4XS3PT is what identifies it as the 4X stainless 3-point latch configuration versus a clamp-latch version of the same 36 x 30 x 12 size.
