NEMA 3 Enclosures

NEMA 3 boxes and enclosures protect electrical equipment in indoor and outdoor settings. Enclosures meeting NEMA Type 3 standards are designed to withstand windblown dust, rain, sleet, and ice formation. Molded from impact-resistant polycarbonate plastic, we have an array of sizes choose from. Styles include a hinged or screw-on cover with the ability to surface mount or pole mount enclosures. A full line of NEMA accessories are available to complete your NEMA 3 enclosure or junction box solution.
