What is the main difference between 8/20μs and 10/350μs in SPD?
8/20μs: Suitable for protection against fast-rising and short-duration surges, such as lightning strikes and rapid switching events.10/350μs: Suitable for protection against slower-rising and longer-duration surges, often associated with power distribution network switching operations and industrial electrical systems.

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.

What is the difference between the magnetic latching type and electrical holding type vacuum contactor?
Vacuum contactors can be classified into two main types based on their mechanism for holding the contacts closed: magnetic latching type and electrical holding type.
