Overview

The ABB TC726US Set Screw Connector, identified by SKU TC726US, is a robust electrical fitting constructed from durable zinc-plated steel. This connector is specifically engineered to facilitate secure and insulated connections within 2-inch EMT (Electrical Metallic Tubing) conduit systems. Its design accommodates both insulated and concrete-tight installation requirements, effectively negating the necessity for conduit threading while establishing a dependable and vibration-resistant electrical bond. A key feature of the TC726US is its hardened hex head cup point screw. This component is instrumental in providing high-quality electrical bonding and is designed to remain captivated, thereby preventing any loosening over the operational lifespan of the connection. The connector also incorporates a nylon insulated throat. This feature significantly eases the process of wire pulling, reducing the effort required by up to 50%. Furthermore, it actively prevents insulation thinning and safeguards against first-thread damage during installation. The TC726US meets and surpasses the stringent code requirements set forth by UL 514B and CSA C22.2 No. 18. Its compliance is further validated by its UL File No. E-23018 and CSA Certifications, specifically LR-2884 and LR-4484. This connector is rated for concrete-tight installations, a critical specification for many construction environments. Additionally, for conduit sizes of 2 inches and above, including this specific model, it is capable of carrying ground fault currents up to an impressive 20,000 amps RMS. The TC726US is an ideal choice for a wide range of industrial and commercial electrical installations, where its inherent durability, strict compliance with safety standards, and long-term performance are paramount, especially in demanding environments. This connector is fully compatible with EMT conduit. It is distributed by Gross Automation and is backed by the established quality standards synonymous with the ABB brand.
