Product classification method

Vacuum interrupters may be classified by enclosure type, by application, and by voltage class, Experimental, radio-frequency, and early power-switching vacuum interrupters had glass enclosures. More recently, vacuum interrupters for power switchgear are made with ceramic envelopes.

Applications and uses include circuit-breakers, generator circuit-breaker, load switches, motor contactors, and reclosers. Special-purpose vacuum interrupters are also manufactured, such as those used in transformer tap changers, or in electrical arc furnace
