Overview

The ABB TC124US Set Screw Connector (SKU: TC124US) is engineered for secure and reliable connections in electrical conduit systems, specifically designed for 1-1/4 inch EMT (Electrical Metallic Tubing). Manufactured by ABB Installation Products, this connector is constructed from durable zinc-plated steel, offering excellent corrosion resistance suitable for demanding environments. Its set screw design provides a positive holding strength and ground connection, eliminating the need for conduit threading. The insulated throat, made of nylon, reduces wire pulling effort by up to 50% and protects wire insulation from damage, preventing first thread damage and thinning of insulation. This connector is approved for concrete-tight applications, ensuring a sealed connection in poured concrete installations. It conforms to UL 514B, CSA C22.2 No. 18, NFPA 70-1999 (ANSI), NEMA FB1, Federal Specification W-F-408, and Federal Standard H-28 (Threads). The TC124US is UL Listed (File No: E-23018) and CSA Certified (LR-2884, LR-4484). Suitable for use with threadless rigid metal conduit or intermediate metal conduit, it can be used to connect conduit to a box or enclosure or to couple conduit ends. The hardened hex head cup point screw ensures a high-quality bond and is captivated to prevent vibration loosening. This connector is capable of carrying ground fault currents up to 10,000 amps RMS for sizes up to 1-1/4 inch. Trust ABB Installation Products for dependable solutions for electrical contractors and industrial applications requiring robust and code-compliant conduit fittings.
