1SAZ211201R2047

ABB 1SAZ211201R2047 TA25DU-19M Thermal Overload Relay is a three-pole electromechanical protection device designed for reliable protection of electric motors against overload and phase-failure conditions. Its thermal current setting can be adjusted between 13.0 A and 19.0 A, allowing the relay to be matched accurately to the motor's rated full-load current. The device uses Trip Class 10A, making it suitable for standard motor-starting applications. The TA25DU-19M is designed for direct mounting onto compatible ABB block contactors, forming a compact motor starter assembly. Key functions include temperature compensation, trip-free operation, STOP and TEST functions, trip indication, and selectable manual or automatic reset
