3 Phase Contactor Diagram. It reveals the parts of the circuit as simplified forms as well as the power as well as signal connections in between the tools. The below wiring diagram shows how we would assemble a complete motor starter with a start stop.
These devices are used when the voltage requirements of the load exceed the power handling capability of a mechanical relay. I had to do this a few times with floodlights to be used outside. Contactors are typically used on three phase air conditioning motors requiring at least 480 volts to operate.
A very first check out a circuit representation may be confusing however if you can read a train map you can review schematics.

Literally a circuit is the path that permits electrical energy to circulation. Starting a three phase motor. 19 less than a minute.
