Overview

The nVent TBHUB20 is an interchangeable bolt-on hub designed specifically for 2.00-inch conduit entry into Type 3R terminal boxes and current transformer cabinets. Engineered from high-quality, zinc and copper-free aluminum, this hub delivers exceptional durability and corrosion resistance, enhanced further by its anodized finish. The hub incorporates an insulated thermoplastic throat that maintains a temperature rating of 105°C, ensuring reliable performance in demanding environments. Its UL94-V0 flammability rating underscores its safety in applications where fire resistance is critical. A key feature is the unique sealing ring design, which provides a complete 360° seal to preserve NEMA 3R, 4, and 13 enclosure integrity, even when conduit alignment is not perfectly perpendicular. Installation is streamlined thanks to the hexagonal/splined body and integrated locknut, which simplify torque application and ensure secure fastening. The hub’s teeth are designed to penetrate the enclosure, delivering improved bonding and grounding performance. Compliance with NEMA sealing requirements is confirmed, and the product holds UL Listing and CSA Certification for added assurance. It is fully compatible with both rigid and intermediate metal conduit systems, making it a versatile solution for a wide range of industrial and commercial applications.
