In a three-phase motor circuit, what is the primary purpose of setting the thermal overload relay trip current specifically to the motor’s full-load amperage rather than its starting current?

The primary purpose of setting a thermal overload relay to the motor’s full-load amperage—the steady current a motor draws when performing its rated work—is to protect the motor from long-term overheating without nuisance tripping during normal operation. A motor requires a high inrush current, known as starting current, to overcome iner....
