Question
could you explain to me what electrical contactors are used for and how they work?

Answer
An electrical contactor is basically a high voltage switch, that is normally actuated by a lower voltage current. (like a relay) There are several types depending on the application, and depending on the type, offer different protection features. (overload, phase lose, etc.)

The typical contactor is a two or three phase relay.

Here is a typical contactor
