NEMA 3R Enclosures
A NEMA 3R enclosure is a type of electrical cabinet that:
Protects components from weather conditions such as rain, snow and ice.
Keeps water, dirt and dust from getting inside.
Prevents personnel from accessing hazardous parts.
Compared to lower-tier NEMA ratings, the NEMA 3R rating can stand up to additional weather conditions, providing comprehensive defense against the elements. This security is why the NEMA 3R electrical enclosure is common for junction and wiring boxes for utilities and communications and for housing other critical electrical components in outdoor environments.
At APX Enclosures, the NEMA type 3R electrical enclosure is one of our specialty protective cabinets. Each cabinet we manufacture is NEMA certified, UL Listed, weatherproof, non-corrosive and highly customizable to your specifications. Your product will be long-lasting and suitable for your application.
