Motor circuits require that their protective devices have specific characteristics to avoid inadvertent operation during the motor starting period. The check made is based on the selected protective device and the motor's starting current and starting duration settings. Based on these parameters the motor starting curve is calculated and compared to the protective device curve. Overlapping between the curves indicates inadvertent operation.

Recommendation to resolve the error:

Revise the protective device so the motor and protective device curves are not overlapping.
