Common Applications for NEMA 4X Enclosures

NEMA boxesNEMA 4X enclosures are designed to protect equipment from damaging environmental conditions such as dirt, rain, ice formation and corrosion.  They are the optimal choice for equipment placed in locations that are frequently exposed to corrosive agents, washdowns or heavy-weathering. There are many applications that require the use of a NEMA 4X enclosure, so we will just touch on a few of the most common places you will find them:

Outdoor Locations

NEMA 4X enclosures are designed to be weatherproof and suitable for outdoor use. These include hot, dusty locations that are subject to wind abrasion, damp locations with lots of rainfall, or cold environments with sleet and ice storms. From the dry west coast to the humid east coast, NEMA 4X enclosures are prevalent.

Washdown Areas

A NEMA 4X enclosure is the ideal solution for equipment that is exposed to frequent washdowns with water or chemical solutions. You can find these boxes in use at facilities such as such car washes, dairy processing plants or any place where high-pressure cleaning equipment is utilized.
