Multiple Choice

A motor starter typically uses a device designed to handle higher current than a standard relay.

The main idea is that motors draw a very high current when they start, known as the inrush or startup current. A motor starter uses a heavy-duty switching device, typically a contactor, that is rated to carry that higher current level and withstand the motor’s startup surge. This is different from a standard relay, which is generally designed for lower control-circuit currents. That’s why a motor starter is built to handle higher current than a typical relay. The other options don’t fit because a motor starter isn’t defined by using a resistor or a transformer to handle motor current. Resistors may appear in some reduced-voltage starting methods, and transformers are used for control power or voltage conversion, not for carrying the motor’s full startup current.
