Function

The Siemens 3RT2016-1UB41 functions as an electromechanical switching device. When the 24 V DC control voltage is applied to its coil, it generates a magnetic field that closes the main contacts. This action completes the power circuit, allowing electricity to flow to the connected load (e.g., a motor).

The integrated varistor suppresses voltage spikes that can occur during switching, protecting both the contactor and the motor. The auxiliary contact provides a signal to the control system, indicating the status of the main contacts (open or closed), which is essential for interlocking, signaling, and safety circuits.
