Function

The Siemens 3TB4222-0XR2 contactor acts as an electrically controlled switch used for switching a power circuit. When the coil is energized, it creates a magnetic field that closes the main contacts, allowing power to flow to the connected load (e.g., an electric motor). When the coil is de-energized, the contacts open, interrupting the power circuit. The integrated auxiliary contacts (1 NO + 1 NC) can be used for control and signaling purposes, such as interlocking circuits or providing feedback on the contactor’s status.
