Looking for a different NEMA rating? Check out our complete line of NEMA rated enclosures. Read more below to learn about the basics of NEMA 5 enclosures and whether they’re right for your needs.
NEMA Rating Basics
NEMA enclosure ratings are a system established by the National Electrical Manufacturers Association to rate the protective qualities of electrical enclosures. These ratings incorporate a wide variety of factors — from waterproofing to corrosion resistance — into a rating scale from 1 to 13 that’s widely used across North America.
One key fact about NEMA standards is that higher numbers don’t necessarily indicate a higher degree of protection. Instead, each rating has its own definition with specific protective requirements. That’s why NEMA 5 rated enclosures offer a lower degree of protection than (for example) NEMA 4X enclosures.
When determining the best NEMA enclosure rating for your application, the first step is to get familiar with the specifics of the various ratings. For more information on the NEMA system and the various enclosure types, see Polycase’s complete guide to NEMA enclosure ratings.
What Is a NEMA 5 Enclosure?
NEMA 5 rated enclosures are qualified for indoor use in environments that require dust tight protection. They’re common in a variety of applications, from office and retail use to certain types of manufacturing facilities. Although a NEMA 5 rating alone isn’t considered sufficient for outdoor use, it’s also common for NEMA 5 enclosures to have additional higher ratings.
You can count on a NEMA 5 enclosure to protect the enclosed equipment from hazards that include:
- Personnel access to hazardous parts
- Solid foreign objects (such as falling dirt, lint, flyings and airborne dust)
- Ingress of water from light splashing and dripping
For more details on the level of protection that NEMA 5 enclosures offer, see our NEMA 5 rating guide.
