Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt; against hose-directed water and the entry of water during occasional temporary submersion at a limited depth; and that will be undamaged by the external formation of ice on the enclosure.
Enclosures constructed for either indoor or outdoor use to provide a degree of protection to the personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt; against hose-directed water and the entry of water during prolonged submersion at a limited depth; and that will be undamaged by the external formation of ice on the enclosure.
Enclosures constructed without knockouts for indoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt; against circulating dust, lint, fibers, and flying; and against dripping and light splashing of liquids.

The National Electrical Manufacturer Association NEMA uses a standard rating system that defines the types of environments in which an electrical enclosure can be used, and frequently signifies a fixed enclosure's ability to withstand certain environmental conditions.
It is NEMA's belief that utilizing standards benefits the user as well as the manufacturer. It improves safety, economics and communication between manufacturer and purchaser. A standard of NEMA defines a product in reference to its attributes and capabilities. We produce quality enclosures in a variety of materials, types and NEMA ratings.
The ratings shown in the chart below are based on similar application descriptions and performance expectations. Download chart. NEMA 1. NEMA 3. NEMA 3R. NEMA 4. NEMA 4X. NEMA Provides a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects. For housing power distribution, lighting contactors, switch gear, and other electrical components.
Houston, TX Type 4X : Same as Type 4 except constructed from corrosion-resistant material. Corrosion-resistant as defined by industry standards is: Constructed to provide a degree of protection against exposure to corrosive agents such as salt spray.
Stainless steel is the strongest of the corrosion resistant materials. It exhibits many of the same resistances attributed to fiberglass materials as well as resistance to highly polar solvents such as acetone and MEK.
Note that grade resistance to sulfates and chlorine is less than that provided by grade. These deposits are often created by contamination resulting from rain or marine environments.
Type 12 : Constructed without knockouts for indoor use to provide a degree of protection to personnel against access to hazardous parts. Provides a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects falling dirt and circulating dust, lint, fibers, and fyings. Also provides a degree of protection with respect to harmful effects on the equipment due to the ingress of water dripping and light splashing.
Nema Enclosures produce NEMA 12 enclosures which are intended mainly for indoor industrial, manufacturing, and machining applications. We produce a number of enclosure types in aluminum, carbon steel and stainless steel delivered quickly at competitive prices. Houston, TX Ph: Fax: All Rights Reserved. Skip to content.
