Function

The Siemens 3RT2038-1AP00-1AA0 power contactor is a remotely operated switch that controls the flow of electrical power to a load, such as an electric motor. When the 230 V AC control voltage is applied to the coil, the magnetic field pulls the main contacts together, allowing power to flow to the motor. When the control voltage is removed, a spring forces the contacts open, disconnecting the power. The auxiliary contacts change state simultaneously with the main contacts, providing a signal that can be used for interlocking, status indication, or other control functions.
