ABB 1SAZ211201R2043 TA25DU-11M Thermal Overload Relay is a three-pole electromechanical motor protection device designed to protect AC motors against overload and phase-failure conditions. Its adjustable thermal current range of 7.50 A to 11.00 A allows accurate matching to the motor's rated full-load current. The relay operates with Trip Class 10A, making it suitable for standard motor-starting applications. The TA25DU-11M is designed for direct mounting onto compatible ABB block contactors, creating a compact motor starter arrangement. ABB specifies features including temperature compensation, trip-free mechanism, STOP and TEST functions, trip indication, and selectable manual or automatic reset.
