Eaton Specification Sheet - STG 9
Zinc construction provides exceptional corrosion resistance, extending service life in harsh industrial environments while maintaining electrical continuity for grounding networks used with Myers hubs. This translates to lower maintenance costs and reduced downtime in hazardous locations where reliability is non-negotiable. The STG 9 is sized for a 3-1/2 inch trade profile, with a compact 5 inch length, 5 inch height, and 3 inch width, weighing 3 pounds, which simplifies installation in tight panels and crowded conduit runs without sacrificing strength or grounding integrity. Its NEC/CEC compliance and NEMA ratings 3, 3R, 4, 4X, and 12 provide clear regulatory alignment and protection against moisture, corrosion, and impact in demanding environments. Documentation availability, including a 3D CAD drawing package and installation sheets, accelerates design-in and procurement workflows, reducing engineering cycle times and risk of errors. UL certification references further support Canada and US installations, delivering confidence for project approvals and field commissioning while supporting long-term maintenance planning and asset lifecycle optimization.
