NEMA 12 enclosures are designed to provide protection against dust, dirt, and fibers, as well as provide some protection against water and oil. The enclosure is typically constructed of sheet steel and includes cover gaskets to further exclude contaminants. NEMA 1 enclosures provide little to no protection against liquids or even dripping water, while NEMA 4 and 7 enclosures are designed for more hazardous locations and may include features such as explosion-proofing and submergibility.
