NEMA 4 Enclosure

NEMA 4 Enclosure

A NEMA 4 enclosure can be found in almost any industry around the world. The National Electrical Manufacturers Association has established the rating system in order to provide the proper guidelines for the encasement of electrical systems that need protection from external corrosives. The ratings are based on a number system where the higher numbers indicate a higher degree of protection the enclosure must have. In non-hazardous locations, there are several different NEMA ratings for specific enclosure "types", their applications, and the environmental conditions they are designed to protect against, when completely and properly installed.

A NEMA 4 enclosure must be constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment. It has to provide a degree of protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, and hose-directed water; and will be undamaged by the external formation of ice on the enclosure. The use of the non metallic NEMA 4 enclosure offers many different advantages to the user. It is much less costly than steel or aluminum and does not corrode.

They are easier to install and can be adapted to fit many different applications. Corrosion is minimal if at all existent and the longevity of the materials long outlasts its heavier more cumbersome counterparts. The most influential characteristic in choosing a non metallic NEMA 4 enclosure over a metallic product is the environment that it will be used. Where the product will be used and what it will be used for basically.

Stahlin products more than fulfill the requirements for a NEMA 4 enclosure. With over 40 years of experience behind their electrical system enclosure solutions they service industries internationally with products that meet and exceed user specifications. The ability to choose from over fifteen different product families to solve needs from the ordinary to the most problematic.

If they do not have a product to fit your needs than they offer programs that will help find solutions. The ModRight and FormRight programs offer services to engineers and designers that help them solve their enclosure dilemmas. Installation is always a factor as well so some consideration must be taken when choosing enclosures. The equipment mounting panel, wiring connections, enclosure mounting, and of course grounding have to be taken into account. Stahlin's non metallic enclosures have proven time and time again their products are superior in performance and price.
