Function

The Siemens 3TB4022-0XL0 contactor acts as an electrically operated switch. When the 125/127V AC coil is energized, it creates a magnetic field that pulls the main contacts together, allowing power to flow to the connected load (e.g., a 4 kW motor). When the coil is de-energized, a spring mechanism separates the contacts, interrupting the power supply and safely turning off the equipment. The auxiliary contacts switch simultaneously with the main contacts, providing status feedback to the control system or enabling logic for complex operations.
