NEMACO™ Stainless steel NEMA 3R floor mount enclosure

TYPE 3R DEFINITION PER NEMA 250 STANDARD

Definition: Type 3R Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow); and that will be undamaged by the external formation of ice on the enclosure.

General References: NEMA 3R Enclosures are similar to NEMA 4 Enclosures in terms of ingress protection. But Type 3R is rain resistant and Type 4 is water spray down resistant.
