Overview

The ABB TC727US Set Screw Connector is a zinc-plated steel fitting designed for 2-1/2 inch EMT conduit, providing a secure, concrete-tight connection in industrial and commercial electrical installations. This connector eliminates the need for conduit threading, simplifying installation while ensuring compliance with NEC and other industry standards. The hardened steel set screw with a captive hex head delivers positive holding strength and ground continuity, while the nylon-insulated throat reduces wire pulling effort by up to 50% and prevents insulation damage. The connector is UL Listed (File No. E-23018) and CSA Certified (LR-2884, LR-4484), meeting UL 514B, CSA C22.2 No. 18, and NFPA 70-1999 requirements. Its concrete-tight design ensures reliable performance in poured concrete applications, making it ideal for use in electrical rooms, control panels, and conduit systems where durability and safety are critical. The TC727US is part of ABB's Installation Products line, a trusted brand in electrical infrastructure solutions. Compatible with EMT conduit sizes from 1/2 inch to 4 inches, this connector is engineered for high-ampacity applications, capable of carrying ground fault currents up to 20,000 amps RMS. The zinc-plated steel construction provides corrosion resistance, while the nylon insulator ensures electrical safety and reduces installation time. Suitable for both indoor and outdoor environments, the TC727US is a versatile solution for electrical contractors, maintenance teams, and industrial facilities requiring dependable conduit connections.
