For retrofit projects, verify existing gland plate spacing and wall or rack mounting allowances to ensure installation efficiency and code compliance.
This enclosure carries IECEx/ATEX certification for hazardous locations, a Class I, Zone 1/Division 2 hazardous rating, and a NEMA 4X/IP66 protection rating. These certifications confirm suitability for explosive atmospheres, ensure reliable ingress protection against dust and water, and support compliance with global electrical safety standards, which is essential for cross-border project procurement.
Yes. The 316L stainless steel construction offers excellent corrosion resistance in hydrocarbon-rich environments, while IP66/NEMA 4X protection guards against dust, water, and chemical exposure. Its hazardous-location certification (Class I, Zone 1) makes it appropriate for upstream and downstream oil & gas installations, where durable, compliant enclosures are critical.
The enclosure supports substantial control gear due to its 98" x 74" x 20" format and 4 gland plates, enabling organized, scalable cabling for 400A electrical systems. Four gland plates provide flexible entry options for different conduit sizes and gland configurations, reducing installation time and enabling clean, compliant cable management in demanding facilities.
The 316L stainless steel body resists corrosion, lowering maintenance frequency in harsh environments. The hinge facilitates quick access for routine inspections and component replacement, minimizing downtime. Combined with IP66/NEMA 4X protection and IECEx/ATEX compliance, this enclosure supports long service life and predictable maintenance planning for hazardous-location facilities.
