What is the term used for the contactor and its associated hardware in motor control?

The term "magnetic motor starter" refers specifically to a device that includes a contactor along with its associated hardware, which is utilized in motor control applications. A magnetic motor starter functions to safely switch on and off electric motors and provides protection against overloads and faults.

In this context, the contactor is a key component that is responsible for making or breaking the electrical connection to the motor. The additional hardware typically encompasses overload relays, typically integrated with the starter, which monitor the motor's current and protect it from overheating or damage due to excessive load conditions.

The use of the term "magnetic" distinguishes it from other types of starters. These starters employ electromagnetic principles to operate, allowing for reliable and efficient control of motor functions.

Overall, the magnetic motor starter is crucial in applications where motors need to be switched frequently and safely while providing necessary protection. This makes it the most fitting descriptor for the combination of the contactor and its hardware used in motor control.
