Overview

The ABB TC129A Set Screw Connector is a precision-engineered electrical fitting designed for secure, long-lasting connections in EMT (Electrical Metallic Tubing) conduit systems. This connector is specifically engineered for 3-1/2 inch EMT conduit, providing a precise fit for standard electrical installations. Constructed from zinc-plated steel, the TC129A delivers superior corrosion resistance and durability in industrial, commercial, and residential applications. Key specifications include a length of 3.906 inches, making it ideal for installations requiring tight, vibration-resistant connections. The set screw design ensures a secure hold that resists loosening over time, eliminating common failure points in conduit systems. The connector features an insulated throat, reducing wire pulling effort by up to 50% and enhancing installation efficiency while lowering labor costs. The TC129A is rated concrete-tight when taped, providing protection against moisture and environmental contaminants in demanding installations. This rating makes it suitable for use in concrete-encased conduit systems, underground applications, and areas exposed to harsh conditions. The zinc-plated steel construction ensures long-term performance in both indoor and outdoor environments. Applications include commercial buildings, industrial plants, data centers, infrastructure projects, and any installation requiring reliable EMT conduit connections. The TC129A's compatibility with standard EMT systems ensures seamless integration into existing electrical infrastructures. Its robust design and precise engineering make it a trusted choice for electrical contractors, maintenance professionals, and industrial facilities seeking durable conduit fittings. Part of ABB's Installation Products line, the TC129A combines proven reliability with straightforward installation. The captive hex head screws tighten down onto the conduit for positive holding strength and ground continuity. This connector is designed to meet the demands of mission-critical electrical installations where secure, long-lasting conduit connections are essential.
