Function
The magnet coil is the primary actuator within a contactor. When energized by the 110V AC power supply, it generates a magnetic field that pulls the movable contacts into a closed position. This action allows the contactor to switch power to an electrical load, such as a motor or heating element. The Siemens 3TY7403-0AG2 coil ensures this critical switching function is performed with precision and reliability.
