What is NO and NC on a contactor?
Answer
NO and NC are abbreviations for Normally Open and Normally Closed respectively.
They are used to describe the state of the contacts on a contactor when the coil is not energized.
NO contacts are open when the coil is not energized and close when the coil is energized.
NC contacts are closed when the coil is not energized and open when the coil is energized.
