Q: What is the primary function of a motor starter?

To control the starting and stopping of a motor and provide overload protection. — Motor starters control motor operation and include protection features.

Q: Which component is NOT typically found in a motor starter?

Resistors — Resistors are often found in starting circuits, not the starter itself.

Q: What does an overload relay protect a motor from?
