Function
The contactor coil is the heart of an electromechanical contactor. When an electrical current flows through the coil, it generates a magnetic field. This field pulls the movable contacts, closing the circuit and allowing power to flow to the connected load. A faulty or worn-out coil can lead to contactor failure, causing operational issues. Replacing it ensures the contactor can reliably make and break the circuit as needed.
