WAVK0304 Louver Plate Kit for NEMA 12 Enclosures

The Wiegmann WAVK0304 is a louvered vent kit designed for NEMA 12 electrical enclosures. It provides passive airflow to help manage internal temperatures. The kit includes all necessary mounting hardware for installation. It suits technicians maintaining or modifying existing enclosures in industrial or commercial settings.

Powder-coated carbon steel frame

The frame measures 4.75 in height by 4.5 in width with a depth of 0.38 in. The required cut-out is 3.5 in high by 3.25 in wide and 0.5 in deep. The grey powder-coated carbon steel construction resists corrosion in typical indoor environments. Louvers allow continuous air exchange without active cooling components.

Simple bolt-on installation using included hardware

Mounting hardware is supplied, so no separate fasteners are needed. The installer must cut the specified opening accurately in the enclosure wall. Misalignment or oversized cut-outs can compromise the NEMA 12 seal. Proper torque on the supplied bolts ensures the gasket seats correctly for the rated protection level.

Questions about this item

Does the .38 in frame depth restrict airflow or increase noise when the enclosure runs continuously?

The .38 in frame depth and 3.5 in by 3.25 in cut-out provide a fixed free area; airflow and sound depend on the fan or convection setup you install, not on the louver plate itself.

What enclosure cut-out and mounting hardware must I already have to fit the 4.75 in by 4.5 in frame?

You need a NEMA 12 enclosure with a 3.5 in high by 3.25 in wide cut-out at least .5 in deep; the kit includes the mounting hardware for that opening.

Will the carbon-steel gray powder-coated frame match the finish on an older NEMA 12 box?

The frame is carbon steel with a gray powder-coated finish, the standard coating used on NEMA 12 enclosures, so it will visually match existing cabinets of the same rating.
