Enclosures rated to NEMA 4X provide the same level of indoor-outdoor protection as a NEMA 4 enclosure but with the addition of corrosion protection. Bud’s enclosures that meet this requirement are made from ABS plastic, polycarbonate plastic, fiberglass, and die cast-aluminum, which are inherently corrosion resistant. See selection tips.
A NEMA 4X box is gasketed and tightly sealed against air-blown dust and contaminants. It also blocks the intrusion of hose directed water, making it an excellent choice for factory washdown and outdoor application. See NEMA 4 selection tips.
Most of our NEMA 4X boxes are available for same-day shipping, and nearly all are in our industry-leading 5-Day Modifications program. Get custom cutouts in only 5 to 6 days.
