Everything You Need to Know About NEMA Ratings When Cooling an Enclosure


Everything You Need to Know About NEMA Ratings When Cooling an Enclosure Photo

A little knowledge goes a long way. When it comes to The National Electrical Manufacturers Association (NEMA) it is important to have a good understanding of the standards (also known as "ratings" or "types") for electrical enclosures commonly used in industrial and other applications. Each NEMA type relates to specific environmental conditions that the enclosure can protect against. Cooling products, such as enclosure air conditioners, heat exchangers, and fans can also have corresponding NEMA types for the environmental conditions to which they will be exposed. It is recommended that the cooling product be matched to an enclosure with the same NEMA type to ensure the components housed within the enclosure are properly protected.

 

Examples of NEMA types include:

  • NEMA 12 – for indoor use, protection from dust and dripping liquids.
  • NEMA 3R – for indoor or outdoor use, protection from rain.
  • NEMA 4 – for indoor or outdoor use, protection from washdown.
  • NEMA 4X – for indoor or outdoor use, protection from corrosive environments.

 

The chart below provides an abbreviated summary of different environmental conditions and the associated NEMA rating required for commonly used enclosure cooling equipment:
