What are the main difference between electrical holding and magnetic holding in vacuum contactor?
In summary, the main difference between electrical holding and magnetic holding in a vacuum contactor is the method used to maintain the closed position of the main power contacts when the coil is de-energized. Electrical holding uses an external electrical circuit to provide continuous holding force, while magnetic holding relies on the energy stored in a permanent magnet to maintain the closed position without an external power supply.
