Function

The Siemens 3RT2016-1BG41 functions as an electrically operated switch. When the 125 V DC control voltage is applied to the coil, it generates a magnetic field that closes the main power contacts. This allows the flow of power to the connected load (e.g., an electric motor). Simultaneously, the integrated 1 NO auxiliary contact also changes state, signaling the “on” status to the control system. When the control voltage is removed, the contacts open, interrupting the power flow and de-energizing the load.
