NEMA 3 Enclosures: Basic Facts
The National Electrical Manufacturers Association maintains the NEMA rating scale to provide information on the protective qualities of electrical enclosures. (Our complete guide to the NEMA rating system includes a full rundown of each NEMA enclosure type.)
NEMA 3 is one of the most common ratings in enclosures designed for outdoor use. Most NEMA 3 models are built with a waterproof gasket that keeps out water and solid particulates (although some NEMA 3R enclosures aren’t). You can count on a NEMA 3 enclosure for a high degree of protection against:
- Adverse weather including rain, snow and sleet
- Light splashing with water
- Falling dirt and windblown dust
- Accidental contact with personnel
The NEMA 3 rating also has several variants with different protective characteristics, including NEMA 3R, NEMA 3S, NEMA 3X and various combinations like NEMA 3RX. For more information on these ratings, see our guide to NEMA 3 vs. NEMA 3R enclosures.
