1SAZ321201R2002

ABB 1SAZ321201R2002 TA75DU-32M Thermal Overload Relay is an electromechanical motor-protection device designed to protect motors against overload and phase-failure conditions. Its adjustable thermal current setting of 22 A to 32 A allows the relay to be matched accurately to the motor’s full-load current. The relay operates with Trip Class 10A, making it suitable for standard motor-starting applications. The TA75DU-32M connects directly to compatible ABB block contactors and provides temperature compensation, trip-free operation, STOP and TEST functions, trip indication, and selectable manual or automatic reset. It incorporates one normally closed trip contact and one normally open signal contact for contactor control, alarms, PLC feedback and remote fault indication.
