ENCLOSURE
NEMACO™ NEMA 3RX enclosures bring stainless steel durability to outdoor electrical protection, constructed from 304 or 316 stainless steel with ASTM A967 passivation for superior corrosion resistance in coastal, chemical, and high-humidity environments where standard painted steel falls short.
American made with smooth-ground welds and precision fabrication, they support optional thermal edge filtered fan systems with free thermal calculations available to match the right cooling solution to ambient conditions and heat load. Custom sizes, BABAA compliance, and expedited delivery make NEMACO™ NEMA 3RX enclosures a specification-ready upgrade for critical outdoor applications demanding both weather and corrosion protection
