Function

The Siemens 3RT2035-1AH00 functions as an electromagnetically operated switch for controlling power to a wide range of electrical loads. When the 48 V AC coil is energized, it closes the main power contacts, allowing current to flow to the connected equipment, such as a motor. When the coil is de-energized, the contacts open, interrupting the power supply. The auxiliary contacts provide feedback on the contactor’s status and can be used to control other components in a circuit, such as indicator lights or interlocking relays.
