Function

The Siemens 3TB4001-0XQ0 contactor serves as an electrically controlled switch for a power circuit. When its coil is energized by the control circuit, the main contacts close, allowing power to flow to the connected load (e.g., an electric motor). When the coil is de-energized, the main contacts open, interrupting the power supply. The integrated 1 NC auxiliary contact changes state in synchronization with the main contacts, providing a signal for other parts of the control system.
