Tips: Basic principle of 4 Pole contactor
When the coil is energized, the static iron core generates electromagnetic attraction, and the moving iron core is sucked. Since the contact system is linked with the moving iron core, the moving iron core drives the three movable contact pieces to operate at the same time, and the contacts are closed, thereby being connected. power supply. When the coil is de-energized, the suction force disappears, and the moving core interlocking portion is separated by the reaction force of the spring, so that the main contact is disconnected and the power is cut off.

How to Use AC Contactor with Relay Under Safe Voltage?

Contactors are widely used in industrial equipment. It is a common application to control 110V/120V/220V/240V AC contactors with 12V/24V/36V DC relays. Users can use this method to control unsafe voltages. This video will show you how to use AC contactor with a relay at safe voltage.
