Overview

The ABB TC111A Compression Connector, SKU TC111A, is a zinc-plated steel fitting engineered for secure EMT conduit termination in concrete-tight applications. Designed for 1/2-inch EMT (Electrical Metallic Tubing), this connector ensures a permanent, leak-proof seal when embedded in concrete or installed in wet or corrosive environments. The compression connection type provides a mechanically strong joint that resists vibration and maintains electrical continuity, critical for long-term reliability in industrial, commercial, and infrastructure projects. The included locknut secures the connector to electrical enclosures or knockout openings, while the ½-14 NPSM threaded entry accommodates standard EMT conduit sizes. Certified for use in indoor and outdoor applications (insulated TC-711A variant for outdoor), the TC111A meets UL File No. E-16592 and CSA File No. LR-12798 standards for conduit sizes ranging from ½" to 4". Typical applications include electrical enclosures, concrete-encased conduit runs, and installations requiring NEMA-rated protection against moisture and debris. The zinc-plated steel construction delivers corrosion resistance and durability, ensuring consistent performance in demanding conditions. Installation requires no special tools beyond standard EMT conduit cutters and a wrench, simplifying field deployment.
