Function

The Siemens 3TB4101-0XN2 contactor serves as an electromagnetic switch, allowing for remote or automatic control of electrical circuits. When the 220V AC coil is energized, the main contacts close, connecting the load (e.g., a motor) to the power supply. The 1 NC auxiliary contact changes state from closed to open, providing a signal that can be used to control other parts of the system, such as indicating the contactor’s ON/OFF status or preventing simultaneous operation of conflicting equipment.
