APX Enclosures: NEMA 4X Enclosures

January 8, 2025

The NEMA 4X electrical enclosure is a specific type of enclosure that meets the following standards:

  • Suitable for indoor and outdoor use, including offshore environments
  • Protection from hose-directed and splashing water
  • Protection from dust and rain
  • Resistant to corrosion

The NEMA 4X enclosure can serve indoor or outdoor in telecommunicationsutilities, manufacturing, oilfield work and many other industries. It is especially common in environments with food products.

The NEMA 4X rating is superior over NEMA 3R for its:

  • Corrosion resistance: The material of a 4X enclosure will better protect against all kinds of corrosion, including salt spray.
  • Water protection: It can protect the equipment from splashing and hose-directed water.
  • Foreign object protection: The 4X is better able to protect equipment from fine-textured material like windblown dust.

APX Enclosures specializes in making this type of protective device. When you order your NEMA 4X weatherproof enclosure, your product will be NEMA certified, UL listed, non-corrosive, weatherproof, made in the USA and customized to your preferences.
