Applications & Use Cases

The ABB TA200DU-150 thermal overload relay is designed for protecting three-phase motors in heavy-duty industrial applications. Typical use cases include motor protection in manufacturing lines, pump stations, compressor drives, conveyor systems, and HVAC installations where sustained overload currents between 110 A and 150 A must be reliably detected and interrupted. Its compact footprint and wide certification portfolio make it suitable for control panels destined for global markets, from North America and Europe to China and the Eurasian Economic Union.
