Function

The Siemens 3RT7026-1AC25 contactor serves as a remotely operated switch. When the coil is energized by the 24V AC control signal, the main contacts close, allowing current to flow to the connected motor or load. Simultaneously, the auxiliary contacts change state (NO becomes closed, NC becomes open), providing feedback or enabling logic in the control circuit. This component is crucial for starting, stopping, and reversing motors, as well as for switching resistive loads in various industrial automation applications.
