22 3 Operating the SAMMS-L V Device of 10 guarantees that a current of 600% of I FLC will cause a trip in 10 seconds or less. In the SAMMS-LV, the protection curves are designed to cause a trip in 90% to 100% of the class time for a current of 600% of I FLC .
23 3 Operating the SAMMS-L V Device 3.19 Stator Protection By selecting the overload class slightly greater than or equal to the motors starting time, the motor model defines an energy I 2 t value. In this value, I equals 600% of the motors full load current and t equals the overload class selected.
