Function

The Siemens 3RT7025-1AG20 contactor’s primary function is to act as an electrically operated switch. When the appropriate AC 110V 50/60Hz coil is installed and energized, the contactor’s main power contacts close, allowing current to flow to a connected load, such as a motor. When the coil is de-energized, the contacts open, interrupting the power supply and safely stopping the load. This mechanism provides reliable remote control for industrial machinery and processes.
