Function

The Siemens 3TB3901-0XF0 Contactor acts as an electrically controlled switch used for switching a power circuit. When the coil is energized by the 110V AC control voltage, it closes the main power contacts, allowing current to flow to the connected load (e.g., a motor). This function is critical for automating machinery and protecting circuits from overloads.
