AC contactors use vacuum interrupter as switching elements, the main circuit moveable and stationary contacts are sealed in the vacuum where the atmospheric pressure is lower than 1×10-2 Pa. Vacuum medium has good isolation and arc extinguishing ability, so the vacuum contactor is characterized as high isolation voltage, small contact stroke, low contact wear, long life and so on.
