TA Series thermal overload relays are used in conjunction with ABB A Line contactors for the protection of motors having a nominal voltage of up to 600 VAC max per UL/CSA (690VAC and 800VDC per IEC). These relays are built to be self‑protecting in the event of an overload until the short circuit protection device is activated.
The TA25DU-1.0 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
