Function

The Siemens 3RT7036-1AN20 contactor acts as an electrically controlled switch used for switching power circuits. When the 220 V AC control voltage is applied to the coil, it energizes and closes the main contacts, allowing high current to flow to the connected load (e.g., an electric motor). When the control voltage is removed, the contacts open, safely de-energizing the circuit. This makes it an essential component for automated and remote control of industrial machinery.
