Overview

The ABB H050-TB is a 1/2-inch zinc hub connector designed for secure conduit termination in Rigid and Intermediate Metal Conduit (IMC) systems, meeting industry standards for durability and performance. The thermoplastic insulating throat, rated at 105°C with a 94V-0 flammability rating, protects conductors from abrasion during wire pulling, reducing the risk of insulation damage. A nitrile (BUNA-N) sealing ring ensures a tight seal against dust, moisture, and contaminants, meeting NEMA 3R, 4, and 13 enclosure requirements for outdoor and indoor applications. The connector’s throat diameter measures 19/32-inch, precisely accommodating standard 1/2-inch conduit for a secure fit. The included locknut secures the connector to panels up to 3/16-inch thick, providing stability and preventing loosening over time. For enhanced corrosion resistance or NEMA 4X ratings, alternative hub materials are available, including aluminum (H050A), chrome-plated (H050CP), or 316 stainless steel (H050GRSST).
