Overview

The ABB STG8-W is a PVC coated zinc grounded hub designed for secure and reliable electrical connections in industrial environments. Manufactured by ABB Installation Products, this hub features a 3-inch (78 Metric) pipe size and a white PVC coating for enhanced corrosion and abrasion resistance. The hub is constructed from zinc with a nominal 0.040" (40 mil) PVC coating bonded to the exterior, ensuring durability. Its insulated throat is molded from 105°C-rated thermoplastic with a UL94-V0 flammability rating, providing superior electrical insulation and safety. The integrated nitrile rubber (Buna-N) sealing ring, with its innovative profile, offers a complete 360° seal, even when the conduit is not perfectly perpendicular to the enclosure. This captive sealing ring resists buckling or slipping during installation. The overall diameter is 4.38 inches (111.25 mm), and it accommodates a maximum panel thickness of 0.25 inches (6.35 mm). The throat diameter measures 2.97 inches (75.44 mm). The hexagonal/splined body and locknut facilitate fast and easy installation. Sharper and deeper teeth on the locknut and body ensure a more penetrating bite for improved bonding to the enclosure. This grounded hub meets NEMA sealing requirements for NEMA 3R, 4 & 13 enclosures and is UL Listed and CSA Certified. The white color provides distinct identification and aesthetic integration. Trust ABB Installation Products for dependable, high-quality components that meet stringent industrial safety and performance standards. SKU: STG8-W.
