Overview

The ABB H600GRATB 6-inch aluminum grounding hub is a UL-listed and CSA-certified solution for Rigid and IMC conduit systems, engineered to ensure reliable grounding and environmental sealing in industrial, commercial, and utility applications. Constructed from zinc or copper-free aluminum, the hub and locknut provide corrosion resistance and mechanical durability, while the thermoplastic insulating throat (rated 105°C, 94V-0 flammability) prevents electrical shorts by isolating the conduit from the grounding system. The Nitrile (BUNA-N) sealing ring delivers IP-rated protection against moisture, dust, and contaminants, meeting NEMA sealing requirements for NEMA 3R, 4, and 13 enclosures. Designed for compatibility with standard Rigid and IMC conduit threads, the H600GRATB simplifies installation while maintaining long-term performance in demanding environments. The grounding hub is ideal for grounding systems in electrical rooms, switchgear enclosures, outdoor installations, and hazardous locations (Class II Groups E, F, G; Class III). The product’s aluminum construction ensures lightweight yet robust handling, while the included locknut secures the hub to the panel or enclosure. Key applications include grounding and bonding in power distribution systems, motor control centers, and industrial machinery where conduit integrity and grounding continuity are critical. The H600GRATB is part of the T&B Grounding Hub series, a trusted solution for electrical contractors and engineers requiring dependable performance in both indoor and outdoor settings.
