Fabricated from carbon steel,  NEMA 12 industrial enclosures are designed to prevent the ingress of dust, water, and oil. NEMA 12 electrical enclosures are most often used for indoor applications of automation control and electronic drives systems. Some examples are packaging, material handling, non-corrosive process control, and manufacturing applications. Gasketed doors seal the enclosure's contents from airborne contaminants and non-pressurized water and oil. These NEMA enclosures are available in sizes from small wall mounts to multi-door freestanding models.
