Eaton NXTS17455200 N-TB Enclosure - IP66 4X Hazardous

316L stainless steel construction provides superior corrosion resistance in chemically aggressive and coastal environments. This material choice extends service life in harsh locations, reduces maintenance frequency, and lowers long-term ownership costs. Applications include chemical processing plants, offshore platforms, and other demanding environments where enclosure durability matters. 74" x 55" x 20" enclosure size supports large assemblies, equipment groups, and cable terminations. The 606 mm horizontal and 540 mm vertical fixing centers enable compatible mounting with common frames and panels, reducing retrofit time. With a 400 A rating and voltage capability up to 690 Vac/Vdc, it can house high-current control circuits while maintaining safe clearances. With hinge for quick access, maintenance tasks are faster and safer, minimizing downtime. Zero gland plates in the base configuration reduce complexity during initial wiring; future gland plate options can be added as needed to accommodate evolving cable management. IP66 and NEMA 4X ratings provide robust ingress protection and corrosion resistance, meeting hazardous location standards. The enclosure aligns with NEC/CEC and IECEx/ATEX certifications, with Class I, Zone 1 and Division 2 hazardous area ratings, supporting safe operation in regulated environments. Clean, simple installation is aided by the hinged design, standardized dimensions, and compatibility with Eaton Crouse-Hinds N-TB family. The lightweight 23.76 kg unit can be installed by a small crew, reducing labor costs, while long-term reliability lowers total cost of ownership in critical processes.
