Function

The Siemens 3TB4422-0XJ2 contactor is an electromechanical switch used to control an electrical power circuit. When a control voltage of 115V AC is applied to its coil, it creates an electromagnetic field that closes the main contacts, allowing power to flow to the connected load (e.g., a motor). When the control voltage is removed, the contacts open, interrupting the power. The integrated auxiliary contacts switch simultaneously, providing feedback to a PLC, relay, or other control system about the contactor’s state. This makes it an essential component for motor starters, heating systems, lighting control, and other power switching applications.
