Function

The Siemens 3RT2028-1AN24 power contactor functions as an electromechanical switch. When the 220 V AC coil is energized, it closes the main power contacts, allowing current to flow to the connected load (e.g., an electric motor). When the coil is de-energized, the contacts open, interrupting the power supply.

The integrated auxiliary contacts (2 Normally Open and 2 Normally Closed) can be used for interlocking, signaling the operational status to a PLC or control system, or for other control circuit functions. The removable auxiliary switch feature offers a unique advantage for maintenance and flexible configuration.
