1SAZ211201R2033

ABB 1SAZ211201R2033 TA25DU-4.0M Thermal Overload Relay is an electromechanical motor-protection device designed to provide reliable and fast protection for electric motors against overload and phase-failure conditions. Its adjustable thermal setting range of 2.80 A to 4.00 A enables the relay to be set according to the motor's rated current. The device operates with Trip Class 10A, making it suitable for motors with normal starting characteristics. The TA25DU-4.0M is designed for direct mounting onto compatible ABB block contactors, resulting in a compact motor-starter assembly. ABB specifies features including temperature compensation, trip-free mechanism, STOP function, TEST function, trip indication, and selectable automatic or manual reset. Single-mounting kits are also available where separate mounting is required.
