Function

The Siemens 3RT1064-6AS36 serves as a power contactor in electrical control systems, primarily functioning to remotely switch three-phase electric motors on and off. It uses a small control voltage (500-550 V AC/DC) applied to its coil (drive) to electromagnetically close and open the main power contacts, safely and reliably controlling the flow of high current (225 A) to the motor. Its integrated auxiliary contacts provide immediate feedback on the contactor’s status to the control system (e.g., PLC).
