Function
The Siemens 3RT2023-2AH00 operates as an electromechanical switching device. Upon application of the 48V AC, 50 Hz control voltage to the coil, the main contacts close, connecting the 3-pole load (e.g., a motor) to the power supply. The integrated 1 NO + 1 NC auxiliary contacts provide feedback on the contactor’s status to the control system (e.g., PLC or relays).
