OverviewHistoryClassificationGenerator circuit-breakerStructureOperationProduction processSealed for lifetime
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. Separation of the electrical contacts results in a metal vapour arc, which is quickly extinguished. Vacuum interrupters are widely used in utility power transmission

In the main body of the paper the design philosophy behind vacuum interrupter contact design is presented. It is shown that only two classes of contact have achieved practical utilization. The first of these design classes causes a magnetic field to be impressed at right angles to the arc current and hence, causes the arc to move rapidly over the contact face.
