Wall-Mount Enclosure BN4-CH

The Wiegmann BN4121005CH is a carbon-steel enclosure rated NEMA 12, 13 and 4 with an IP66 ingress-protection rating. It measures 10 inches wide, 12 inches high and 5 inches deep, finished in gray ANSI 61 powder coat. A hinged solid cover secures with screw-down clamps over a neoprene gasket. External mounting plates and a 6XC22 interior panel are included for component installation.

Suited For Fixed Industrial Wiring

This enclosure serves installers who need a wall-mounted, clamps-sealed cabinet for line-protection devices or bus plugs in environments rated for NEMA 12, 13 and 4. It is not suited for applications requiring a transparent cover, a deeper usable opening than 4.88 inches, or a different material such as stainless steel or non-metallic construction. Buyers needing a larger footprint or a different NEMA rating should consider other series.

NEMA 12, 13, 4 And IP66 Rating

The decisive specification is the combined NEMA 12, 13, 4 and IP66 rating, which defines the dust, water and oil-tight protection level the enclosure provides. This rating determines whether the cabinet meets the environmental requirements of the installation site. Verify that the rating matches the specification called for in your project documents before ordering.

Questions about this item

How does the 14/16 ga carbon-steel body with IP66 gasket handle heat when the enclosure runs continuously?

The 14/16 gauge carbon-steel walls and neoprene gasket dissipate heat passively; no fan or active cooling is built in, so internal temperature rise depends on the installed components and ambient conditions.

What mounting hardware must I already have to install this 10×12×5 in wall-mount enclosure?

The unit ships with external mounting plates; you supply the lag bolts or anchors suited to your wall material and a screwdriver or nut driver for the screw-down clamps.

Will my existing 6XC22 interior panel fit the usable 4.88 in depth of this BN4-CH series box?

Yes — the 6XC22 panel is designed for this series and mounts within the 4.88 in usable depth, leaving adequate clearance for wiring and terminals.
