Function

The Siemens 3RT7035-1AV00 contactor acts as an electrically operated switch. When the 400VAC, 50 Hz control coil is energized, it closes the main power contacts, allowing current to flow to the connected motor or load. When the coil is de-energized, the contacts open, safely cutting off power to the load. Its primary function is to provide reliable and frequent switching of motors under load conditions (AC-3), protecting the motor and control system.
