Overview

The ABB TC721A Set Screw Connector, SKU TC721A, is engineered by ABB Installation Products for secure and reliable connections in electrical conduit systems. Constructed from durable zinc-plated steel, this connector is designed for 1/2-inch EMT conduit, offering a robust solution for industrial and commercial installations. Its set screw connection type ensures a positive hold and ground, while the insulated throat significantly reduces wire pulling effort by up to 50% and prevents insulation damage. This connector meets and exceeds code requirements for bushings, safeguarding wire insulation and preventing first thread damage. Key features include its concrete-tight application capability, making it suitable for installations where conduit is embedded in concrete. The 1.365-inch length ensures proper alignment and stability within the electrical system. The zinc-plated steel material provides excellent corrosion resistance, ensuring long-lasting performance even in harsh environments. The captive hex head screws are hardened to provide a high-quality bond and will not vibrate loose, ensuring system integrity. The TC721A is listed and certified by U.L. (File No: E-23018) and CSA (LR-2884, LR-4484), conforming to U.L. 514B, CSA C22.2 No. 18, NFPA 70-1999 (ANSI), NEMA FB1, Federal Specification W-F-408, and Federal Standard H-28 (Threads). This connector is ideal for connecting and effectively bonding threadless rigid metal conduit or intermediate metal conduit to boxes or enclosures, or for coupling ends of threadless conduit. Its thickwall steel body and hardened hex head cup point screw contribute to its robust design. The TC721A is capable of carrying ground fault currents up to 10,000 amps RMS for sizes up to 1-1/2 inch, and 20,000 amps RMS for sizes 2 inches and above, ensuring safety in fault conditions. Choose the ABB TC721A for dependable, code-compliant conduit connections.
