Function

The Siemens 3RT2023-2AB00 functions as a remote-controlled electrical switch. When the 24 V AC coil is energized, it generates a magnetic field that pulls the main contacts into a closed position, allowing current to flow to the connected load (e.g., an electric motor). When the coil is de-energized, the contacts open, interrupting the power. The auxiliary contacts switch simultaneously with the main contacts, providing a signal for control and interlocking circuits, such as for status indication lights or for cascading multiple contactors.
