Painted mild steel construction combines durability with cost efficiency, giving the STBPS151509 a robust protective shell without the premium price of stainless alternatives. The enclosure supports a compact footprint of 15x15x9 inches and a mounting pattern with 175 mm horizontal fixing centers, which translates to predictable integration with standard panels. For panel builders, this means fewer fabrication steps and more consistent panel depth. IP66 sealing delivers reliable ingress protection against dust and powerful wash-downs, significantly extending service intervals in harsh environments. This translates to lower maintenance costs and less unplanned downtime in manufacturing floors and outdoor installations. The combination of IP66 and a corrosion-resistant paint finish also improves longevity in chemical processing plants. NEC Class I, Division 2 hazardous-location rating, together with IEC/CEC standards, enables safe use in areas with flammable vapors. This expands deployment options for chemical plants, refineries, and offshore facilities where enclosure integrity directly affects equipment reliability. The enclosure's area classification label helps procurement teams document compliance quickly during audits. Rated for 400A with up to 690 Vac/Vdc, the STBPS151509 handles medium-sized power and control circuits within a single enclosure. The 175 mm horizontal fixing center ensures straightforward compatibility with existing frame hardware, while the 150 mm length and 90 mm width fit within standard panel cavities, enabling fast commissioning and simplified cable management. Finished with durable paint, the mild steel enclosure resists corrosion in mixed environments, while its light 1.9 kg weight aids handling during installation and service. The enclosure's rigid construction reduces deformation risks and supports long-term uptime, ensuring predictable lifecycle costs. For customers seeking scalable expansion, the STBPS151509 integrates smoothly with other STB series enclosures.
