Yes. Plan for mounting on a flat, sturdy surface compatible with 316L stainless steel in hazardous areas. The NXTS18664201 features a hinged door and a single gland plate, preserving IP66 and NEMA 4X protection while enabling safe conduit entry. Ensure enclosure orientation, adequate service access, and electrical terminal clearance per IECEx/ATEX and NEC/CEC requirements to maintain sealing integrity.
Key specifications include a 400A rating, enclosure size 86 x 64 x 20 inches, weight 29 kg, material 316L stainless steel, one gland plate, and hinge-enabled access. It carries IP66 and NEMA 4X protections, and IECEx/ATEX NEC/CEC certification for hazardous locations (Class I, Division 2; Zone 1). This combination supports reliable field installations and simple commissioning.
Yes. NXTS18664201 is designed for Class I Division 2 and Zone 1 environments and carries IECEx/ATEX and NEC/CEC certifications. With IP66 and NEMA 4X protection, the enclosure safeguards equipment from dust, water ingress, and corrosion in hazardous locations such as oil and gas, chemical processing, and offshore facilities. This ensures compliant installations while reducing risk and maintenance needs over the life of the system.
316L stainless steel offers superior corrosion resistance in aggressive industrial settings, enabling longer service life and lower maintenance costs. In chemical plants, refineries, and offshore platforms, it resists pitting and staining, while the enclosure’s gasketed, hinged design maintains a reliable seal against dust and moisture. This material choice also supports hygiene and cleaning standards in regulated industries.
Maintenance focuses on preserving seals and mechanical integrity. Regularly inspect the gasket, hinges, and gland plate seal; clean with compatible solvents; verify IP66/NEMA 4X seals remain intact after operations; schedule periodic audits to ensure ongoing IECEx/ATEX compliance. The stainless steel construction reduces corrosion-related maintenance and extends lifecycle, delivering lower total cost of ownership.
