Function

The Siemens 3TB4001-0XP0 contactor acts as an electrically operated switch. When the 230 V AC coil is energized, it generates a magnetic field that pulls a core, causing the main power contacts to close. This allows the flow of current to the connected load, such as a motor. De-energizing the coil opens the contacts, interrupting the power flow. The 1 NC auxiliary contact changes its state in tandem with the main contacts, providing a signal for external control circuits.
