1SAZ321201R2003

ABB 1SAZ321201R2003 TA75DU-42M Thermal Overload Relay is an electromechanical motor protection device designed to protect three-phase motors against overload and phase failure. Its adjustable setting range of 29 A to 42 A allows the relay to be matched to the motor’s rated full-load current. The device operates with Trip Class 10A, making it suitable for normal motor-starting applications. The TA75DU-42M provides temperature compensation, trip-free operation, STOP and TEST functions, trip indication, and selectable manual or automatic reset. It includes one normally closed trip contact and one normally open signal contact for contactor control, PLC feedback, alarm signaling, and remote fault indication.
