Function

A contactor is an electrically controlled switch used for switching a power circuit. The Siemens 3TB4322-0XN1 functions by using an electromagnet to close or open its main power contacts when the control coil is energized. The 220V AC, 60Hz coil activates the internal mechanism, allowing power to flow to the connected load. The auxiliary contacts change their state simultaneously with the main contacts, providing crucial feedback for the control system. This enables automation, safety interlocking, and remote control of machinery.
