Technical Function

The Siemens 3TB4110-0XN1 functions as an electrically operated switch. When the $220V$ AC, $60Hz$ coil is energized, it generates a magnetic field that pulls the main contact armature. This action closes the three main power contacts, allowing current to flow to the connected load (e.g., an electric motor). Simultaneously, the $1$ NO auxiliary contact also closes, providing a signal for the control circuit. When power to the coil is removed, the contacts open, interrupting the power flow to the load.

This contactor is designed to handle the specific inrush currents and operational demands of AC-3 category loads, such as squirrel-cage motors during starting.
