316L stainless steel construction delivers excellent corrosion resistance in chemical and saline environments, extending enclosure life and reducing replacement costs. This translates to lower maintenance cycles and longer uptime for critical drives and controllers in refineries, chemical plants, and offshore facilities. The IP66 and NEMA 4X ratings provide robust ingress protection against dust and powerful water jets, minimizing field faults and cleaning costs while supporting outdoor or wash-down environments. A 400 A current rating and 690 Vac/Vdc capability enable direct mounting of high-power equipment within a compact footprint, simplifying control panel layouts and reducing enclosure totals. The two gland plates and hinged door streamline field wiring, accelerate commissioning, and support flexible cable management in tight installations. IECEx/ATEX and NEC hazardous-location certifications give audit-ready compliance for Class I Zone 1/Zone 2 environments, reducing risk and rework. Horizontal and vertical fixing centers (316 mm and 170 mm) align with common mounting patterns, easing retrofit and new-install projects in process, utility, and marine sectors.

FAQs
Installing the NXTS12626202 N-TB involves mounting the 26" x 26" x 20" enclosure on standard supports using the 316 mm horizontal and 170 mm vertical fixing centers. The two gland plates simplify entry for cables, while the with-hinge door supports easy access for terminations. Ensure connections are rated for 690 Vac/Vdc and that a compliant grounding path is established per NEC/IECEx requirements.
The enclosure carries IECEx/ATEX certifications and NEC Class I Zone 1/Zone 2 hazardous location ratings, along with a NEMA 4X enclosure rating and IP66 ingress protection. These certifications confirm suitability for explosive atmospheres and severe outdoor conditions, enabling compliant installation in oil and gas, chemical processing, and general hazardous-area applications.
Yes. The NXTS12626202 is rated for 690 Vac/Vdc, making it suitable for high-power drives and power distribution within a compact 26" x 26" x 20" footprint. It includes two gland plates for organized cable entry and termination, allowing flexible gland configurations to match field wiring while maintaining IP66/NEMA 4X protection.
Industries with corrosive or wash-down environments gain the most value, including chemical processing, oil and gas, water treatment, and offshore platforms. The 316L stainless steel construction resists chlorides and chemicals, while the enclosure’s hazardous-location ratings ensure safe electrical distribution and controller protection in challenging sites.
Maintenance benefits include extended enclosure life due to 316L corrosion resistance and reduced cleaning in dirty environments. The robust sealing and high ingress protection minimize fault rates, lowering downtime. A hinged door and adjustable gland entries speed commissioning and retrofit, delivering faster project timelines and a lower total cost of ownership.
