CHAPTER 5: SETTINGS
If the motor starting times are well within the safe stall times, it is recommended that the
469 Standard Overload Curve be used. The standard overload curves are a series of 15
curves with a common curve shape based on typical motor thermal limit curves (see the
figure and table below).
