Function

The Siemens 3RT2017-1AH01 functions as an electrically controlled switch used for switching an electrical power circuit. When the 48 V AC coil is energized, the main contacts close, allowing power to flow to the connected load (e.g., an electric motor). Simultaneously, the normally open (NO) auxiliary contact also closes, which can be used for control circuit feedback or interlocking. The robust design ensures it can handle high inrush currents typical of motor starting applications (AC-3e/AC-3).
