NEMA 3RX Enclosures

NEMA 3RX enclosures are constructed for indoor or outdoor use. NEMA 3RX enclosures provide the same protection as NEMA 3R enclosures, but with an added level of corrosion protection. Find a range of convenient sizes and styles of NEMA 3RX enclosures and junction boxes molded from polycarbonate plastic for electrical applications.

Understanding NEMA 3RX Enclosures

The NEMA 3RX rating, as established by the National Electrical Manufacturers Association, means an electrical enclosure provides a strong degree of protection against:

  • Rain, snow and sleet
  • Falling dirt
  • Ingress of water from light splashing
  • Corrosion
  • Access to or contact with hazardous parts

These characteristics make NEMA 3RX enclosures a common choice for protecting electrical equipment in both outdoor and indoor applications. Like NEMA 3R enclosures, they’re not always required to include a gasket seal, although many models are built with one in order to satisfy multiple ratings at once.

Note that the NEMA 3RX is just one of several variant ratings under the NEMA 3 standard. Others include NEMA Type 3R, 3S and 3SX, and each has slightly different protective qualities. For more information on these, see our NEMA 3 vs. NEMA 3R guide, or our comprehensive guide to NEMA ratings.
