Function

This Siemens contactor functions as an electrically controlled switch. When the 24V AC 60Hz coil is energized, it creates a magnetic field that pulls the main contacts closed, allowing current to flow to the connected load (e.g., a motor). De-energizing the coil releases the contacts, disconnecting the power. The integrated auxiliary contacts switch simultaneously with the main contacts, providing status feedback or controlling other circuits in a control system.
