Mitsubishi Electric Corporation announced today that it produced its four-millionth vacuum interrupter in June 2015, 50 years after launching production of these environmentally friendly devices for interrupting and carrying electric current in vacuums that require no insulation gas. The company is now the largest producer in Japan, and seventh worldwide, on an annual basis.
The historic four-millionth vacuum interrupter was produced at Mitsubishi Electric’s Power Distribution Systems Center in Marugame-city, Kagawa prefecture, which has been handling production since 1990.
Vacuum interrupters are installed mainly in vacuum circuit breakers and load-break switches as key components for interrupting and carrying electric current. Approximately 80 percent of these products are installed in vacuum circuit breakers produced by Mitsubishi Electric, and the rest are sold as components. The company is now expanding global sales of components by leveraging its half-century of manufacturing experience.
