Function

The magnet coil is the heart of a contactor’s operating mechanism. When energized, it creates a magnetic field that pulls the armature, which in turn closes the main contacts. This action allows the flow of power to a motor or other electrical load. The Siemens 3TY7403-0AS0 ensures this critical function is performed reliably and consistently, providing a stable control signal for your machinery.
