Key Features & Benefit

• High Performance: Capable of handling demanding AC-3 applications up to 32A and 15kW, ensuring reliable motor control.
• Compact Design: The Size S0 form factor saves valuable panel space, allowing for more efficient layouts.
• Durable Connections: Screw terminals offer a strong, vibration-resistant connection, reducing maintenance and improving safety.
• Versatile Use: Ideal for a wide range of applications, including motor control, lighting, and heating systems.
• Long Service Life: Built with Siemens’ renowned quality and engineering, providing a long operational life and high reliability.

Function

The Siemens 3RT7027-1AG20 contactor acts as an electrically operated switch, primarily used for controlling three-phase electric motors. When the 110V AC coil is energized, the magnetic field it creates pulls the main contacts closed, allowing current to flow to the motor. When the coil is de-energized, a spring forces the contacts open, safely interrupting the circuit. This makes it a crucial component in industrial automation and power distribution systems.
