Function
The Siemens 3RT2038-3AN20 functions as an electromagnetically operated switch for remote switching of three-phase motors and other electrical loads. When the 220 V AC coil is energized, the three main contacts close, connecting the load to the power supply. The integrated 1 NO + 1 NC auxiliary contacts provide feedback or enable interlocking functions within the control circuit.
