1SAZ211201R2040

ABB 1SAZ211201R2040 TA25DU-8.5M Thermal Overload Relay is an electromechanical motor-protection device designed to provide reliable protection for three-phase motors against overload and phase-failure conditions. Its adjustable thermal current setting from 6.00 A to 8.50 A allows the protection level to be matched to the motor's full-load current, while its Trip Class 10A makes it suitable for normal motor-starting applications. The relay is designed for direct mounting on compatible ABB block contactors, creating a compact contactor-and-overload-relay motor starter assembly. Key functions include temperature compensation, trip-free operation, STOP and TEST functions, trip indication, and selectable manual or automatic reset.
