A NEMA enclosure is a standardized case or housing designed to protect electrical equipment and control devices.
NEMA enclosures are primarily a standard used in North America and are utilized to protect electronic equipment from external environments across various industries and applications. To accommodate different purposes and environmental conditions, there are various types and grades such as waterproof, dustproof, corrosion-resistant, and explosion-proof.
The types and characteristics of enclosures are based on standards established by NEMA. For example, NEMA 1 enclosures are suitable for general indoor applications and provide dustproofing but not waterproofing. NEMA 4X enclosures are suitable for outdoor or high-moisture environments and offer waterproofing, dustproofing, and corrosion resistance.
