NEMA 3R Enclosures

Milbank’s NEMA 3R products meet the standard rating system set by the National Electrical Manufacturer Association (NEMA). This standard defines a product in attributes and capabilities and assures a certain level of quality. Milbank NEMA 3R enclosures are designed for either indoor or outdoor use and provide a degree of protection to internal equipment against water (including rain, sleet and snow). NEMA 3R enclosures are also designed to be undamaged by the external formation of ice on the enclosure.

Below you’ll find a brief overview of different types of NEMA 3R enclosures that Milbank offers.
