NEMA 4X Enclosures

NEMA 4X enclosures and boxes from Polycase provide both indoor and outdoor solutions for your watertight electronics application. Meeting NEMA 4X test standards ensures our enclosures are designed for electronic products located in harsh environments. With a variety of styles and sizes available, it’s easy to find the ideal NEMA 4X enclosure solution. We offer enclosures in ABS plastic, polycarbonate plastic, aluminum, steel and stainless steel.

Per NEMA, enclosures meeting 4X standards are constructed for indoor or outdoor use and provide protection to internal components against ingress of windblown dust, rain, sleet, snow, splashing water, and hose directed water. They also provide an additional level of protection against corrosion and will be undamaged by the external formation of ice.
