Function

The Siemens 3RT2038-1AN24 functions as an electromechanical switch for controlling the flow of high currents in electrical circuits. When the 220 V AC coil is energized, it closes the main power contacts, allowing current to flow to the connected load (e.g., an electric motor).

Simultaneously, the auxiliary contacts change state, providing feedback or control signals to a programmable logic controller (PLC) or other control system. De-energizing the coil opens the main contacts, interrupting the power flow and shutting down the load.
