Function

The Siemens 3TB4010-0XU0 contactor is an electromechanical switching device. When the 240V AC 50 Hz coil is energized, it generates a magnetic field that pulls the main contacts together. This action closes the circuit, allowing power to flow to the connected load (e.g., a 4 kW motor). The integrated 1 NO auxiliary contact also changes state, providing a signal that the contactor is engaged, which can be used for interlocking or status indication in a control system.
