Function

The Siemens 3TB4022-0XK1 contactor’s primary function is to act as an electrically operated switch. When a 120V AC, 60 Hz signal is applied to its coil, the internal mechanism closes the main contacts, allowing power to flow to the connected load. Simultaneously, the auxiliary contacts change state—the NO contact closes and the NC contact opens—to provide feedback or control signals to other parts of the system. This makes it an indispensable component for automating the control of motors and other high-current devices.
