Tips: Basic principle of AC 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.
