ABB TA75DU-32 Thermal Overload Relay TA75DU-32

ABB TA75DU-32 thermal overload relay is a three‑pole device that protects motors in the main circuit from overload and phase failure. It provides a 22 to 32 A current setting range for three‑phase loads and is rated for up to 690 V AC, enabling use with a broad range of industrial motor circuits. Described by ABB as an economical electromechanical protection device for the main circuit, the TA75DU‑32 features a trip class of 10 A, defining its overload protection curve. This relay is designed for panel mounting alongside contactors to deliver integrated motor protection in control gear assemblies. Typical use includes protecting motors in industrial equipment where reliable overload and phase-loss protection is required. The TA75DU‑32 is part of ABB’s TA75DU thermal overload family, a line of compact devices that provide predictable performance in standard low-voltage motor circuits.
