Overview

The ABB TC128A Set Screw Connector (SKU: TC128A) is a precision-engineered, zinc-plated steel fitting designed for secure, concrete-tight EMT conduit connections in industrial and commercial electrical installations. This 3-inch conduit connector features a set screw design that eliminates the need for conduit threading, providing a fast, reliable installation with positive holding strength. The connector is UL-listed (File No: E-23018) and CSA-certified (LR-2884, LR-4484), ensuring compliance with NFPA 70 (NEC) and CSA C22.2 No. 18 standards for electrical safety and performance. Key specifications include a 3.641-inch length, zinc-plated steel construction for corrosion resistance, and compatibility with 3-inch EMT conduit. The set screw mechanism tightens onto the conduit for a stable, vibration-resistant connection that reduces the risk of loosening over time. The connector also features an insulated throat, reducing wire-pulling effort by up to 50% compared to non-insulated fittings. This design minimizes abrasion damage to conductors during installation, improving long-term reliability. Ideal for applications requiring robust, corrosion-resistant conduit connections, the TC128A is commonly used in manufacturing facilities, commercial buildings, and industrial control systems where durability and electrical integrity are critical. The concrete-tight mounting ensures a secure fit in poured concrete or masonry installations, preventing moisture ingress and maintaining system integrity. The zinc-plated finish provides additional protection against rust and corrosion, extending the product's lifespan in harsh environments. ABB Installation Products, a trusted name in electrical infrastructure solutions, delivers this connector with the reliability and precision expected from a global leader in industrial fittings. Whether for new installations or maintenance upgrades, the TC128A provides a dependable, code-compliant solution for EMT conduit connections in demanding applications.
