ENCLOSURE
NEMACO™ NEMA 3R enclosures deliver proven outdoor protection against rain, sleet, and falling dirt for electrical and control equipment in utility, industrial, and infrastructure applications.
Available in powder-coated steel or powder-coated aluminum, they offer a durable, cost-effective solution for standard outdoor weather exposure where stainless-steel construction isn't required. American made with smooth welds and precision fabrication, they support optional thermal edge filtered fan systems, with free thermal calculations available to match the right cooling solution to your ambient conditions and heat load. Custom sizes, BABAA compliance, and expedited delivery keep projects on schedule and on specification
