When the AC contactor is energized, the internal coil generates a magnetic field, causing the moving iron core and the stationary iron core to attract each other. This movement drives the contact system to engage with the stationary contacts, completing the circuit. When the coil is de-energized, the attraction force disappears, and the reset spring lifts the moving iron core, separating the contacts and breaking the circuit.
