316L stainless steel construction provides excellent corrosion resistance in demanding environments, extending service life and reducing maintenance costs for critical power and control systems. This directly translates to fewer replacements and lower total cost of ownership in chemical plants, offshore platforms, and food & beverage facilities. IP66 and NEMA 4X protection safeguard internal components from dust, water jets, and washdowns, significantly reducing downtime and enabling reliable outdoor or harsh-environment installations. In hazardous locations, IECEx/ATEX and NEC/CEC compliance together with Class I, Division 2 rating streamline approvals, accelerating project timelines and cross-border deployments. The 38 x 38 x 22 inch footprint, 435 mm horizontal and 250 mm vertical fixing centers, plus two gland plates, support flexible routing and easy field upgrades. The 690 Vac/Vdc rating and 400 A capacity deliver robust power handling for motor starters, controllers, and drive systems. Availability of 316L stainless steel, corrosion resistance, and a rugged enclosure design helps operators minimize maintenance cycles and extend asset life, even in coastal or chemical processing environments. The enclosure is compatible with standard Eaton Crouse-Hinds accessories, enabling seamless integration with existing electrical infrastructure and simplifying retrofit projects.
