Function

The Siemens 3RT2027-1AF00 power contactor serves as an electromechanical switch to remotely control the flow of electrical power to a load, typically an electric motor. When the 110 V AC control coil is energized, it closes the main power contacts, allowing current to flow to the motor.

The auxiliary contacts simultaneously change state, providing feedback to a control system (e.g., a PLC) or enabling interlocking logic. When the coil is de-energized, the main contacts open, safely disconnecting the motor from the power supply.
