ABB 1SAZ211201R2031 TA25DU-3.1M Thermal Overload Relay is an electromechanical motor-protection relay designed to protect three-phase motors against overload and phase-failure conditions. It provides an adjustable thermal current setting of 2.20 A to 3.10 A, allowing the relay to be matched accurately to the motor’s full-load current. The relay operates according to Trip Class 10A, making it suitable for motors with standard starting characteristics. The TA25DU-3.1M is designed for direct connection to compatible ABB block contactors, creating a compact motor-starter assembly. It incorporates temperature compensation, a trip-free mechanism, STOP and TEST functions, trip indication, and selectable automatic or manual reset.
