Overview

The ABB TK125A Set Screw Coupling, SKU TK125A, is a critical component for secure and reliable electrical conduit installations. Manufactured by ABB - Installation Products, this coupling is specifically designed for 1-1/2 inch EMT (Electrical Metallic Tubing) conduit. Constructed from durable steel with a zinc-plated and chromate-coated finish, it offers excellent corrosion resistance for both indoor and outdoor applications. The set screw design eliminates the need for conduit threading, providing a faster and more efficient installation process. Each coupling features captive hex head screws that tighten directly onto the conduit, ensuring positive holding strength and a reliable ground connection. Furthermore, the TK125A is equipped with an insulated throat, which significantly reduces wire pulling effort by up to 50%, protecting wire insulation during installation. This coupling is approved for concrete-tight applications, ensuring the integrity of electrical systems in demanding environments. It conforms to UL 514B, CSA C22.2 No. 18, NFPA 70-1999 (ANSI), NEMA FB1, Federal Specification W-F-408, and Federal Standard H-28 (Threads). Certified by UL (File No: E-23018) and CSA (LR-2884, LR-4484), the TK125A meets stringent industry standards for safety and performance. Its precise 3.060-inch length ensures a proper fit for 1-1/2 inch EMT conduit. Trust ABB's commitment to quality for your industrial, commercial, and residential electrical projects.
