Everything You Need to Know About NEMA Ratings and Enclosure Cooling

image-03-big.png

 

Like with a lot of things, a little knowledge goes a long way.

The National Electrical Manufacturers Association (NEMA) has set standards, or ratings for various types of electrical enclosures, most commonly used in industrial applications.Each NEMA type relates to

specific environmental conditions that the enclosure can protect against. Cooling products, such as Air Conditioners , Heat Exchangers, and Fans can also have corresponding NEMA types for the environmental conditions that they can be exposed to.It is recommended that the cooling product be matched to an enclosure with the same NEMA type to ensure the components within the enclosure are properly protected.

Some examples of NEMA types include NEMA 12 (indoor use, protection from dust and dripping liquids), NEMA 3R (indoor or outdoor use and rainproof), NEMA 4 (indoor or outdoor use, protection from washdown) and NEMA 4X (indoor or outdoor use, protection from corrosive environments). The below chart is an abbreviated summary of different environmental conditions and the associated NEMA rating required for commonly used  enclosure/cooling equipment:image-03b-1.png
