History and over 40 years of experience

Since vacuum interrupters were first launched, tremendous strides have been made in Japan. Mitsubishi Electric began the research and development of vacuum interrupters in the early 1960s. Since its first vacuum interrupter entered the market in 1965, Mitsubishi Electric has continued to play a pioneering role in the field. Since then, over 40 years of experience and up to date technologies result in compact and extremely reliable vacuum interrupters making Mitsubishi Electric the leading vacuum interrupter company in Japan. Mitsubishi vacuum interrupters are in service in equipment such as vacuum circuit breakers, vacuum contactors, and load break switches all over the world.
