Overview

The ABB TC221-SC-5 Non-Insulated Set Screw Connector is a precision-engineered electrical fitting designed for secure, reliable conduit connections in industrial and commercial applications. Manufactured by ABB Installation Products, this connector features a durable die-cast zinc construction, ensuring long-term resistance to corrosion and mechanical stress. The 1/2-inch conduit size accommodates standard electrical installations, while the 1-5/32-inch length (TC221 series) and 1-17/64-inch width provide optimal compatibility with existing conduit systems. The 15/64-inch width ensures a snug fit for 1/2-inch conduits, eliminating the need for threading and simplifying installation. Key features include captive hex head screws that tighten down onto the conduit for positive holding strength and ground continuity. The non-insulated design allows for direct metal-to-metal contact, making it ideal for grounding applications. The connector is U.L. listed under File No. E-23018 and CSA certified under LR-2884 and LR-4484, meeting NFPA 70-1999 (ANSI) and NEMA FB1 standards. The electro-zinc plated and chromate-coated finish enhances corrosion resistance, while the nylon insulator reduces wire-pulling effort by up to 50%, improving installation efficiency. Packaged in a convenient bag of 5, the TC221-SC-5 offers cost-effective solutions for bulk purchases, making it a practical choice for electrical contractors, maintenance professionals, and industrial equipment installers. Trust ABB Installation Products for dependable performance in demanding electrical systems.
