Overview

The ABB TC723US Set Screw Connector is a precision-engineered electrical fitting designed for 1-inch EMT conduit installations. Manufactured by ABB Installation Products, this connector features a durable zinc-plated steel body that delivers superior corrosion resistance and long-term reliability in commercial and industrial environments. The set screw design ensures a secure, vibration-resistant connection that maintains electrical continuity and grounding integrity, critical for code-compliant installations. Key specifications include a 1-inch conduit size compatibility with EMT conduit systems, meeting UL 514B and CSA C22.2 No. 18 standards. The connector incorporates a nylon-insulated throat that reduces wire-pulling effort by up to 50% while preventing insulation damage and first-thread stripping—a common issue in threaded connections. This insulated throat also eliminates the need for additional bushings, simplifying installation and reducing material costs. Certified concrete-tight, the TC723US maintains environmental sealing in wet or outdoor locations, making it suitable for underground, concrete-encased, or exposed conduit runs. The hardened hex-head set screw provides positive holding strength and ground fault current capacity up to 20,000 amps RMS for sizes 2 inches and above (10,000 amps for 1-inch and smaller sizes). The captive screw design prevents loosening from vibration, ensuring long-term performance in high-stress applications. Ideal for electrical contractors, maintenance teams, and industrial facility managers, this connector streamlines EMT conduit installations by eliminating threading requirements while delivering a mechanically secure, code-compliant connection. Its zinc-plated finish resists oxidation in harsh conditions, extending service life in corrosive atmospheres. Trust ABB Installation Products for reliable electrical components that meet rigorous industry standards without compromise.
