Function

The coil is the heart of a contactor. When an electrical current flows through the coil, it generates a magnetic field. This magnetic field then pulls a plunger, which closes or opens the contactor’s main contacts. This action allows the contactor to switch a high-power electrical circuit on or off in response to a low-power control signal. Replacing a faulty coil is a common maintenance procedure that restores this essential magnetic action, allowing the contactor to function properly again.
