• Simple Installation: Easy-to-use screw terminals ensure quick and secure wiring.
• Versatile Application: Suitable for a wide range of motor and non-motor loads in various industrial environments.

Function

The Siemens 3RT7017-1AH02 contactor functions as an electrically operated switch. When the 48V AC control voltage is applied to the coil (terminals A1 and A2), the magnetic field generated pulls the main contacts together, allowing power to flow to the connected load (e.g., an electric motor). When the voltage is removed, a spring returns the contacts to their open position, safely de-energizing the load. The 1NC auxiliary contact operates in reverse; it is normally closed when the contactor is de-energized and opens when the contactor coil is energized. This function is crucial for creating interlocking circuits, status signaling, and control logic.
