Overview

The ABB TC717US Compression Connector is a zinc-plated steel fitting engineered for secure, concrete-tight connections with 2-1/2 inch EMT conduit. 18 standards. The compression connection type ensures a tight fit with a current rating of 20,000 amps RMS for sizes 2 inches and above, making it ideal for applications requiring maintained ground fault current capacity. The TC717US features a nylon insulated throat that reduces wire pulling effort by up to 50%, minimizing insulation damage during installation. Its zinc-plated steel construction delivers corrosion resistance for harsh environments, including manufacturing plants, construction sites, and industrial automation systems. The connector includes a locknut for knockout installations and supports threaded entries, providing versatility for both indoor and outdoor use (insulated versions only). With a length of 3.267 inches and compatibility with 2-1/2 inch EMT conduit, the TC717US simplifies installation workflows while ensuring a positive ground path and mechanical protection. The product is part of the TC-700 series, designed for EMT conduit fittings with sizes ranging from 1/2 inch to 4 inches.
