Function

The Siemens 3RT7027-1AV05 contactor’s primary function is to switch electrical power to a load, typically a three-phase motor.

• Power Switching: It acts as a remotely-controlled switch, allowing a low-power control signal to turn on and off a high-power circuit.
• Motor Control: Specifically for AC-3 operation, it’s designed to make and break the current of a running motor.
• Safety and Interlocking: The built-in auxiliary contacts can be used for safety circuits (e.g., to indicate the contactor’s state) or for interlocking to prevent conflicting operations in a control system.
