Description
TA75DU-52M Thermal Overload Relay by ABB
The TA75DU-52M (36.0-52.0A) is an economic electromechanical thermal overload relay designed for the main circuit. It provides reliable and fast protection for motors against overload or phase failure with a trip class of 10A. Key features include temperature compensation, a trip contact (NC), signal contact (NO), selectable automatic or manual reset, trip-free mechanism, STOP- and Test function, and trip indication. The overload relays directly connect to block contactors with single mounting kits available as accessories.
