ABB T75-42DU-TAD Overload Relay

ABB T75-42DU-TAD overload relay is a thermal overload protection device designed to pair with ABB TA42DU/TA75DU contactors to guard three‑phase motors in low‑voltage control circuits. The TA75DU42 variant is rated for 29–42 A, making it suitable for mid‑sized motor loads such as pumps, fans, and conveyors in industrial settings. As part of ABB’s TA family of thermal overload relays, it provides thermal tripping responsive to motor current to prevent overheating and motor damage, helping maintain equipment longevity in everyday operation. The relay is intended for integration with ABB contactors in standard motor control panels, delivering compact, reliable protection for motors used in manufacturing, HVAC, and material‑handling environments. When used with the matching TA42DU/TA75DU contactors, it forms a cohesive protection module that safeguards windings from overload and stall scenarios without requiring extensive wiring or separate protection devices. The TA75DU42 model is commonly specified in ABB’s catalog and is available through ABB’s official channels and authorized distributors, ensuring compatibility with ABB’s low‑voltage motor control ecosystem and consistent maintenance practices. Applications span a broad range of three‑phase motor duties where reliable thermal protection and straightforward integration with ABB control gear are priorities.
