ABB 1SAZ211201R2017 TA25DU-0.63M Thermal Overload Relay is an electromechanical motor-protection relay designed to protect three-phase motors against overload and phase-failure conditions. Its adjustable current setting range of 0.40 A to 0.63 A allows precise matching with the motor's rated operating current. The relay has a Trip Class 10A, making it suitable for normal motor-starting applications. The TA25DU-0.63M is intended for direct mounting onto compatible ABB block contactors, creating a compact motor starter arrangement. It provides temperature compensation, trip-free mechanism, STOP and TEST functions, visible trip indication, and selectable manual or automatic reset.
