Difference between a Contactor and a Motor Starter?
ANSWER:
A contactor is an electrically controlled switch used for switching power circuits, typically in industrial applications.
It’s designed to handle large currents and is often used to control motors.
On the other hand, a motor starter is a device that combines a contactor with overload protection and is specifically used to start and stop motors.
The motor starter protects the motor from overloads and faults by monitoring current flow.
Essentially, a motor starter includes a contactor as well as additional protective features for motor control.
