Function

The primary function of the Siemens 3TB4110-0XG1 contactor is to remotely switch a high-power electrical circuit. When the 110V AC control coil is energized, it generates an electromagnetic force that pulls the main contacts together, allowing current to flow to the connected load (e.g., an electric motor). When the control voltage is removed, a spring forces the contacts apart, breaking the circuit. The integrated auxiliary contact mirrors the state of the main contacts, providing a signal that can be used to indicate whether the contactor is on or off, or to control other parts of the system.
