Question:

<< What is the operation of a contactor based on? >>

Answer: on an electric control.

Decomposed into four main parts (the main circuit, the control circuit, the auxiliary circuit and the motor component), the contactor makes it possible to establish or cut the current in a power circuit, therefore making it possible to control any receiver at distance (resistance furnace, ring or cage motor) or a receiver automatically (resistance, motor, shunt). The operation of the contactor is based on whether or not the electromagnet activates the control circuit. The activation of this electromagnet will cause a movement in translation of the movable assembly of the contactor, and cause the main poles to come into contact, with the consequence of whether or not current flows in the circuit. To choose the correct contactor, pay attention to the values ​​assigned to the contactor such as the rated operating voltage and to the category of use (in the form AC-1, AC-4, etc.). Also take a close look at the electrical endurance of your contactor. You too, send us your DIY question.
