Alternate Catalog No. : TA25DU1.8

Catalog No. : 1SAZ211201R1025

Description:  TA25DU-1.8 Thermal Overload Relay

UPC: 4013614216534

The TA25DU-1.8 thermal overload relay is an economic electromechanical protection device for the main circuit. It offers reliable and fast protection for motors in the event of overload or phase failure. The device has trip class 10A. Further features are the temperature compensation, trip contact (NC), signal contact (NO), automatic- or manual reset selectable, trip-free mechanism, STOP- and Test function and a trip indication. The overload relays are connected directly to the block contactors. Single mounting kits are available as accessory.
