What is the main difference between Tesys "U" and Tesys "T" ?

- Tesys "U" is a motor starter used instead of the conventional starting methods (Motor CB + Contactor + Thermal Overload) and it provides full coordination performance and it is used up to 15 KW (much more better than type 1 and type 2 coordinations)
- Tesys "T" is a Motor protection relay that supports different types of communication (profibus - Modus - Ethernet ...) and is used for motor protection of the LV level from under & over voltage, frequency changes, reversing power direction and many other LV protection functions.
