What is Magnetic contactor
What is Magnetic contactor ? A magnetic contactor is an electromechanical switch that uses a magnetic field to safely control high-power electrical loads, like motors, lights, and heaters, by turning them on/off remotely, acting like a heavy-duty relay for industrial automation, ensuring separation between low-power control circuits (like PLCs) and high-power circuits for protection. When energized, its coil creates a magnetic force that pulls contacts together, allowing current to flow; when de-energized, the magnetic field drops, and springs open the contacts, stopping the current.
