Function

The Siemens 3RT7027-1AF00 functions as an electrically operated switch. When the 110V AC coil is energized, it creates a magnetic field that pulls the main contacts together, allowing power to flow through to the connected load, such as a motor. When the coil is de-energized, a spring mechanism returns the contacts to their open state, disconnecting power. This mechanism allows for the safe and remote control of high-power circuits.
