Function
The Siemens 3RT2035-3AL16 power contactor is a crucial component in industrial automation and electrical systems. It functions as an electrically controlled switch, allowing for the remote and automatic ON/OFF control of electrical loads, particularly motors. When the 230 V AC control coil is energized, it creates a magnetic field that pulls the main contacts together, closing the circuit and allowing power to flow to the connected load.
The auxiliary contacts simultaneously change their state, providing signals for interlocking, status indication, and other control functions. When the coil is de-energized, the main and auxiliary contacts return to their original state, interrupting the power flow.
