Overview

The ABB TC128US Set Screw Connector, manufactured by ABB - Installation Products, is engineered for secure and reliable connections of 3-inch EMT (Electrical Metallic Tubing) conduit in demanding concrete applications. This connector is specifically designed to be concrete-tight, ensuring a sealed environment that prevents the ingress of concrete or other materials during installation. Constructed from durable zinc-plated steel, the TC128US offers superior corrosion resistance, guaranteeing longevity and consistent performance even in harsh industrial and commercial settings. The set screw mechanism provides a positive holding strength, allowing for a tight and adjustable fit onto the conduit, which also contributes to effective grounding. A key feature highlighted in the T&B® Fittings catalog is the insulated throat, which significantly reduces wire pulling effort by as much as 50%, simplifying the installation process and protecting conductors. This connector conforms to UL 514B and CSA C22.2 No. 18 standards, and is listed/certified by UL (File No: E-23018) and CSA (File No: LR-2884, LR-4484), underscoring its compliance with stringent electrical safety regulations. It is also compliant with NFPA 70-1999 (ANSI), Federal Specification W-F-408, and Federal Standard H-28 (Threads). The TC128US is ideal for applications where conduit enters enclosures or conduit bodies at right angles, eliminating the need for conduit threading. Trust ABB Installation Products for robust, code-compliant conduit fittings that ensure the integrity and safety of your electrical systems. SKU: TC128US.
