Description
TA75DU-42M Thermal Overload Relay by ABB
TA75DU-42M (29.0-42.0A) thermal overload relay is an economic electromechanical protection device for the main circuit. It offers reliable and fast protection for motors in the event of overload or phase failure. The device has trip class 10A. Further features include temperature compensation, trip contact (NC), signal contact (NO), automatic or manual reset selectable, trip-free mechanism, STOP and Test function, and a trip indication. The overload relays connect directly to block contactors, and single mounting kits are available as accessories.
