Nemaco offers NEMA 3R electrical enclosures with a full range of cabinet configurations including wall mount, floor mount, free standing and custom configurations. Our NEMA 3R rating series can be used for both indoor or outdoor environments as rain resistant solutions. The enclosures are designed to provide protection against rain, snow, ice, falling dirt, windblown dust/dirt and dripping from leaking pipes for indoor or outdoor locations. We provide various material for these cabinets, carbon steel, powder coated steel, however, for customers needing more corrosion resistant then they should consider requesting aluminum, powder coated aluminum or (304/316L) stainless steel instead.
These type of cabinets can be considered as rain resistant enclosures, normally NEMA 3r doesn’t have gasket to provide dust protection. Customer should keet this in mind, and compare between NEMA 3, 3x, 3r and 3rx for options and benefit of protection each rating provide.
