Function

The Siemens 3TB4010-0XL0 functions as an electrically operated switch. When the 125/127V AC coil is energized, it generates a magnetic field that pulls the main contacts closed, allowing power to flow to the connected load. When the coil is de-energized, springs force the contacts open, interrupting the power supply. The auxiliary contact operates simultaneously, providing a signal that indicates the main contactor’s status to other parts of the control system.
