Purpose-built enclosure

The HOFFMAN A404CH is a carbon-steel electrical box rated NEMA 12 and 13 with an IP65 rating. It suits installers who need a wall-mounted housing for wiring, terminals or small control gear in indoor environments where dust, dripping water or oil are present.

Build integration

The 4 in height and 3 in depth enclosure uses a hinged solid cover secured by screw-down clamps and a neoprene gasket. Weld nuts accept a mounting panel or terminal blocks directly, so no separate bracket kit is required. Powder-coated gray finish resists corrosion on the job site.

Sustained operation

The 14/16 ga steel body and clamped seal maintain their protection rating under continuous exposure to splashing liquids and airborne particulates. The fixed hinge and clamp design prevents cover loosening from vibration or thermal cycling over long service periods.

Questions about this item

How does the 14/16 gauge carbon steel hold up under sustained industrial vibration?

The 14/16 gauge carbon steel construction with welded seams provides rigid structural integrity that resists deformation under continuous mechanical vibration in fixed installations.

What thermal rise occurs inside the sealed IP65 enclosure during all-day operation?

The powder-coated carbon steel body dissipates heat through its surface area; internal temperature rise depends on installed component wattage and external ambient conditions.

What mounting hardware must I supply to attach the box using the weld nuts?

You need machine screws or bolts matching the weld nut thread size to secure the enclosure to a wall or panel through the integrated mounting points.
