B-Line 12126-4XFCHSC Eaton series JIC panel enclosure

The Eaton B-Line 12126-4XFCHSC carries a NEMA 4X rating, so it is built for outdoor and washdown duty: hosedown, windblown dust and rain, and corrosion resistance. The fiberglass body and stainless screws are what get it the X (corrosion) part of the rating, which is why it holds up in food plants, car washes, coastal sites and chemical areas where a painted steel box rusts out.

Outside dimensions are 13.56 inches high, 13.38 inches wide and 6.36 inches deep. The nominal 12126 designation points to a 12 x 12 x 6 interior class, so a 12 x 12 panel-mount subplate is the size to plan around; the extra outside inches are the flange, hinge and cover lip. Measure your device stack against the 6.36 inch outside depth before committing, since a deep contactor plus wire bending space eats that fast.

Yes. The 12126-4XFCHSC ships with external mounting feet and is set up for wall mounting, so all four fasteners land outside the sealed cavity. That matters on a 4X box: nothing you drill for mounting breaks the enclosure's seal or its corrosion barrier. Any conduit entries you cut still need the correct rated fittings to keep the rating.

The 12126-4XFCHSC is built to UL 50, the standard for enclosures for electrical equipment, and country of origin is the United States. That combination is what most government, healthcare and education procurement groups need on the submittal before a box goes on the wall.

Hinged. Both the closure and the cover on the 12126-4XFCHSC are hinged, single-door style, so the lid stays with the box when you open it up for service. For a technician working off a ladder or in a wet area, that is the difference between a one-hand open and juggling a loose cover and eight screws.

Fiberglass, like this 12126-4XFCHSC, is the usual pick where chemicals or salt air are the problem and the box does not need to take physical abuse: it will not corrode at all and at 8.3 pounds a single person can hang it. Stainless is the choice where impact, vandalism or high-pressure washdown against the panel is expected, or where a specification calls out metal for grounding continuity. Both can be NEMA 4X; the decision is corrosion versus mechanical toughness and weight.

What the enclosure is specified with is the hinged cover, external mounting feet and stainless screws. Plan on ordering the interior backpanel, any latch or lock kit beyond the supplied hardware, and your cord grips or rated conduit hubs as separate line items so your bill of material is complete before the install crew shows up.

Order it as 12126-4XFCHSC, an Eaton B-Line series JIC panel enclosure, model designation 4XFCHSC. The 12126 prefix carries the nominal 12 x 12 x 6 size and 4XFCHSC identifies the 4X fiberglass hinged cover construction, so distributors should quote the full string rather than the size alone.

It comes grey and unfinished, which is the standard molded fiberglass look, no topcoat. That is normal for an industrial JIC box and most buyers leave it as-is. If a facility standard calls for a specific color match across a plant, plan on field painting with a coating suited to fiberglass rather than expecting a factory finish option.
