316L stainless steel construction delivers superior corrosion resistance in chemical and offshore environments, translating to reduced repaint cycles, lower maintenance, and longer service life for critical control panels. This improves uptime and lowers lifecycle costs while supporting compliant installations in challenging areas. The enclosure size—60" x 40" x 22"—paired with 400 mm depth, 600 mm height, and 220 mm width, provides ample internal space for wiring, power distribution, and control modules, accelerating installation and future upgrades. Three gland plates enable clean, organized cable management and faster assembly, reducing field labor time and risk of ingress. IP66 and NEMA 4X protections, plus NEC Class I, Division 2, deliver robust barrier performance against dust, water, and corrosive atmospheres, ensuring safety and regulatory alignment. These features work together to minimize downtime and simplify compliance in oil & gas, chemical processing, and heavy manufacturing environments. Industry-standard fixing centers (456 mm horizontal, 464 mm vertical) support straightforward retrofits and compatibility with legacy switchgear, while maintaining strict material and surface finish requirements for cleanroom-adjacent facilities.
