Function

The Siemens 3RT2028-1AV60 contactor primarily functions as an electromechanical switch. When the coil is energized by the 480V AC, 60 Hz control voltage, the main contacts close, allowing power to flow to the connected load. The auxiliary contacts provide status feedback to the control system (e.g., PLC or relays), indicating whether the main contacts are open or closed. The built-in 1 NO + 1 NC configuration offers flexibility for various control circuit designs.
