ABB 1SAZ321201R2005 TA75DU-63M Thermal Overload Relay is an electromechanical motor-protection device designed to protect three-phase motors against overload and phase-failure conditions. Its adjustable current setting range of 45 A to 63 A enables the relay to be matched to the motor’s rated full-load current. The device operates with Trip Class 10A, making it suitable for standard motor-starting applications. The TA75DU-63M provides temperature compensation, trip-free operation, STOP and TEST functions, trip indication, and selectable manual or automatic reset. It is designed for direct connection to compatible ABB block contactors, forming a compact motor starter arrangement.
