Vacuum interrupter with ceramic housing. In electrical engineering, a vacuum interrupter is a switch which uses electrical contacts in a vacuum. It is the core component of medium-voltage circuit-breakers, generator circuit-breakers, and high-voltage circuit-breakers.
Shop-Vac was founded by Martin Miller in 1953 under Craft Tool Company of New York. Miller wanted to replace the broom and dust pan in his workshop with a vacuum cleaner capable of collecting wood and metal chips too large for a conventional machine.
Autoreclosers are made in single-phase [6] and three-phase versions, using oil, vacuum, or sulfur hexafluoride (SF 6) interrupters. Controls for the reclosers range from the original electromechanical systems to digital electronics with metering and SCADA functions. The ratings of reclosers run from 2.4–38 kV for load currents from 10–1200 ...
Vacuum circuit breakers have minimal arcing (as there is nothing to ionize other than the contact material). The arc is quenched when it is stretched a very small amount (less than 3 mm (0.1 in)). Vacuum circuit breakers are frequently used in modern medium-voltage switch gear to 38 000 volts.
