Industrial enclosure for electrical equipment

The Wiegmann N12202006 is a NEMA 12 and 13 rated wall-mount enclosure built from 14-gauge carbon steel with a painted gray finish. It measures 20.0 in high by 20.0 in wide by 6.0 in deep and provides a usable opening depth of 5.88 in for component installation. The solid hinged cover secures with clamps and includes a hasp and staple for padlocking. It is designed for indoor use where protection against dust, dirt and non-corrosive liquids is required.

Mounting and integration requirements

External mounting feet allow direct wall attachment without additional brackets. The seamless polyurethane poured-in-place gasket maintains the environmental seal around the perimeter. A 3A922 interior panel is included for mounting DIN rail, terminal blocks or other control devices. The clamps operate without tools, enabling quick access for wiring changes or inspection while the enclosure remains fixed to the wall.

Sustained environmental performance

The carbon steel construction and painted finish resist corrosion in humid or wash-down conditions typical of NEMA 13 environments. The poured gasket retains its seal over long periods without compression set, maintaining the rated ingress protection through thermal cycling. CSA certification and cULus listing confirm compliance with applicable safety standards for continuous service in industrial control applications.
