Function

The Siemens 3RT2016-1AN21 power contactor acts as a remote-controlled switch for high-current loads. When the 220V AC control voltage is applied to the coil, the main contacts close, allowing power to flow to the connected equipment (e.g., an electric motor). Simultaneously, the 1 NO auxiliary contact also changes state, which can be used to provide feedback to a Programmable Logic Controller (PLC) or to control other components in the system. The screw terminals offer a simple and secure method to connect both the main power lines and the control circuit wires.
