Industrial Wall Enclosure

The Wiegmann BN4060604CHSS is a 304 stainless steel enclosure rated NEMA 12, 13, 4 and 4X with an IP66 ingress rating. It measures 6.0 in high by 6.0 in wide by 4.0 in deep and is built from 16-gauge material with a smooth grained silver finish. The hinged solid cover uses screw-down clamps and a seamless polyurethane gasket. It suits installers protecting bus plugs or similar components in wash-down or corrosive indoor and outdoor locations. Buyers needing larger internal volume or a different mounting footprint should look elsewhere.

Included Hardware

The unit ships with the 6XC20 interior panel, stainless steel mounting screws and the external mounting plates already fitted. Clamps for the cover closure are also supplied so the enclosure can be sealed immediately after wiring. No additional gasket material or separate panel fasteners are required. Installers who prefer a different panel size or a window cover will need to source those parts separately.

Installation Notes

Wall mounting is straightforward using the external plates and the supplied stainless steel screws. The hinged cover swings open for full interior access and the screw-down clamps compress the poured-in-place gasket evenly when tightened in a cross pattern. Over-tightening the clamps can distort the thin 16-gauge flange and compromise the seal. Ensure the mounting surface is flat to avoid stressing the enclosure body.

Questions about this item

Does the 304 stainless steel enclosure need any scheduled gasket replacement or corrosion maintenance?

The seamless polyurethane poured-in-place gasket is integral to the enclosure and the 304 stainless steel construction resists corrosion without a scheduled replacement interval.

What thermal limit appears first when the BN4-CHSS enclosure runs continuously at full load?

The 16 ga metal gauge and IP66 seal limit heat dissipation, so internal component temperature rise becomes the governing constraint under sustained operation.

How much fan noise or extra power draw should I expect from the hinged cover and clamp hardware during all-day use?

The enclosure has no fan or active cooling; the solid cover, screwdown clamps and external mounting plates add no acoustic or electrical load.
