• Automation Ready: The integrated 1 NO auxiliary contact offers flexible possibilities for interlocking, signaling, and control circuit integration.

Function

The Siemens 3TB4110-0XR0 contactor acts as an electrically operated switch. When the control coil is energized by the 415V AC supply, it closes the main power contacts, allowing current to flow to the connected load (e.g., an electric motor). Simultaneously, the auxiliary contact switches its state, providing a signal that the main contacts are closed. This function is crucial for motor starting, stopping, and reversing circuits, as well as for automating power control in industrial processes. The screw terminals ensure a strong, vibration-resistant connection for both the main and auxiliary circuits.
