Overview

The nVent HOFFMAN ZonEx ATEX- and IECEx-certified enclosure (SKU: ATEX745520SS61) provides robust protection for electrical components in Zone 1 and Zone 2 hazardous areas. Constructed from 1.5mm thick Type 316L stainless steel with a #4 brushed finish, it offers superior corrosion resistance and mechanical strength. This enclosure meets ATEX Directive 2014/35/EU, IECEx, and AEx standards, ensuring compliance in potentially explosive atmospheres. Key features include full-width welded wall-mounting brackets, internal weld studs for flexible panel or DIN rail mounting, and M6 brass bonding provisions for grounding. The continuous one-piece gasket delivers IP66 protection against dust and water jets. An optional silicone gasket extends the operating temperature range from -55°C to +180°C, compared to the standard polyurethane gasket's -40°C to +70°C. The ZonEx is designed for increased safety (Ex e) applications, not explosion-proof or flame-proof (Ex d). It is ideal for oil and gas, chemical processing, pharmaceutical manufacturing, food and beverage, water treatment, and mining operations. The enclosure comes fully assembled with cover, mounting plate, and mounting accessories, simplifying installation. Its Type 316 stainless steel construction resists chlorides and acids, making it suitable for coastal and chemical environments.
