Nema Cabinet Ratings

If unsure of the enclosure rating that is required of your project please refer to the design chart below.

Nema cabinet ratings.

Each of these ratings indicate different levels of protection against ingress of solids and liquids. Nema 3r 4 4x 6 6p and 12. Nema is a rating system for equipment that might be exposed to liquids rain ice corrosion and contaminates such as dust. Also it protects electrical types of equipment used and aboard ship docks construction sites and even equipment used in subway systems or tunnels.

Electrical equipment in hazardous areas. The testing method of nema 12 rating is consist of 2 tests. In the electrical world nema stands for national electrical manufacturers association an association of us based equipment manufacturers that produce standards used by many equipment manufacturers. 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.

Enclosures constructed for indoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment and to provide a degree of protection against falling dirt. Ip code iec ingress protection code a similar standard. Nemaco provides quality electrical enclosures that adhere to nema rating standards. Nema ratings for enclosures.

Nema connector another common but mostly unrelated set of standards from nema. See ip codes nema. National electrical manufacturers association nema. Nema rating ip equivalent nema definition protection against solids protection against liquids.

Nema enclosure ratings are similar to iec ip codes and can offer the same protections but cannot be mapped directly. At nema enclosures our knowledge and experience in nema rated enclosures is so extensive it s in our name. We offers designs that adhere to 6 different nema enclosures ratings. Nema enclosure ratings define where an enclosure was designed to be used and the level of protection it was designed to provide.

Nema 3 enclosures are manufactured and designed to protect household electrical controls rotating equipment generator skids. Call nemaco if you have any additional technical questions about electrical enclosures. The chart will assist in specifying which enclosure rating is appropriate for the environment and application needed.
