Function

The Siemens 3RT2025-2AP04 serves as an electrically operated switch for a power circuit. When the 230 V AC control voltage is applied to the coil, it closes the main power contacts, allowing current to flow to the connected load.

The integrated auxiliary contacts change state simultaneously, providing signals for monitoring or interlocking other components within the control system. The removable auxiliary switch offers a flexible solution for different control logic requirements.
