Function

This Siemens 3TB3922-0XM0 contactor acts as an electrically operated switch. When the coil is energized by the 220V AC control voltage, it closes the main power contacts, allowing current to flow to the connected load (e.g., a motor). Simultaneously, the auxiliary contacts change state—the NO contact closes and the NC contact opens—to provide signaling, interlocking, or control functions for the rest of the system.
