Function

The primary function of the Siemens 3TB4122-0XL2 is to act as an electromechanical switch. When the 230V AC coil is energized, it closes the main power contacts, allowing current to flow to the connected load. The auxiliary contacts change state simultaneously, providing a signal that can be used for control circuits, status indication, or safety interlocking. This functionality makes it a critical component in motor starters, control panels, and automation systems.
