NEMA Ratings for Outdoor Enclosures
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. 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.
NEMA 3R
- Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts
- To provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt)
- To provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow)
- And that will be undamaged by the external formation of ice on the enclosure
NEMA 4
- Indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts
- To provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt and windblown dust)
- To provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow, splashing water, and hose directed water)
- And that will be undamaged by the external formation of ice on the enclosure
NEMA 4X
- Indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts
- To provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (windblown dust)
- To provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow, splashing water, and hose directed water)
- That provides an additional level of protection against corrosion
- And that will be undamaged by the external formation of ice on the enclosure
NEMA 12
- Constructed (without knockouts) for indoor use to provide a degree of protection to personnel against access to hazardous parts
- To provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt and circulating dust, lint, fibers, and flyings)
- And to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (dripping and light splashing)
