Function

The Siemens 3TB4222-0XC2 contactor functions as an electrically operated switch. When the 24V AC coil is energized, it closes the main power contacts, allowing current to flow to the connected load, such as an electric motor. The auxiliary contacts simultaneously change their state (NO becomes closed, NC becomes open), providing feedback or control signals to other parts of the system, such as PLCs, indicator lights, or interlock circuits. De-energizing the coil opens the main and auxiliary contacts, safely disconnecting the load.
