1SAZ211201R2021

ABB 1SAZ211201R2021 TA25DU-1.0M Thermal Overload Relay is an electromechanical motor-protection relay designed for reliable protection of three-phase motors against overload and phase-failure conditions. Its adjustable current setting range of 0.63 A to 1.00 A allows the protection level to be matched to the motor's rated current, while Trip Class 10A makes it suitable for normal motor-starting duties. The TA25DU-1.0M is designed for direct mounting on compatible ABB block contactors, creating a compact motor-starter combination. Features include temperature compensation, trip-free mechanism, STOP and TEST functions, visible trip indication, and selectable manual or automatic reset.
