Overview

The ABB TC727A Set Screw Connector (SKU: TC727A) is a UL-listed and CSA-certified solution for connecting 2-1/2" EMT conduit to enclosures or couplings without threading. Constructed from durable steel with a zinc-plated and chromate-coated finish, this connector ensures corrosion resistance and long-term reliability in industrial and commercial environments. The hardened hex head cup point screw provides a vibration-resistant bond, while the nylon insulated throat prevents insulation damage and reduces wire-pulling effort by up to 50%. Designed for concrete-tight applications, the TC727A meets NFPA 70 (NEC), U.L. 514B, and CSA C22.2 No. 18 standards, making it suitable for hazardous locations where general-purpose equipment is permitted (Class I, Div. 2; Class II, Div. 1 & 2; Class III, Div. 1 & 2). The connector carries ground fault currents up to 20,000 amps RMS, ensuring robust electrical system integrity. With a 3.406" length and positive center stop, it delivers secure, code-compliant connections in demanding installations. Ideal for electrical contractors, maintenance teams, and industrial professionals seeking a dependable, code-approved conduit fitting. The TC727A is specifically engineered for EMT conduit applications, providing a reliable and efficient solution for electrical installations requiring concrete-tight sealing and high-performance grounding.
