NEMA 4X & SLP

Meaghan Steele Swanson • May 11, 2022

A NEMA (National Electrical Manufacturers Association) Certification is used for rating various grades of electrical enclosures. It defines the standard in which enclosures are certified to provide protection against environmental conditions such as dust, water, corrosion, oil or coolant.

What does this have to do with SLP? Well, many of our Citadel enclosures, such as the Citadel 2, Citadel 2 Narrow 4’, Citadel 4/4i, and Citadel 4s carry a NEMA 4X rating. What does this really mean? It means that these fixtures are rated for indoor or outdoor use primarily to provide a degree of protection against corrosion, windblown dust and rain, splashing water, hose directed water, and damage from external ice formation. In addition, SLP also offers a Remote Enclosure, rated for NEMA 4X and NEMA 13. NEMA 13 adds additional protection from oil and non-corrosive coolants. SLP takes enclosure protection seriously!
