What Is A NEMA Rating?

The NEMA rating system was created by the United States National Electrical Manufacturers Association and rates the degree of protection against corrosion, gasket aging and construction practices against designated environmental conditions. In our case, we’re referring to NEMA ratings for outdoor aluminum enclosures intended to be used for DVR’s, PoE network switches, CCTV fiber modems and more. Anything above a 4 (4, 4X) is for fully submersible applications such as in a marine environment, or hazardous materials such as at a Government or Nuclear facility.
