Mitsubishi Electric Experience

The first generation Bottle was introduced in 1965. Since then, more than 2,424,000 Mitsubishi Vacuum Bottles have been installed world-wide in Mitsubishi Circuit Breakers and more than 100,000 OEM Vacuum Bottles have been sold annually.

Mitsubishi Electric Power Products has 19,725,000 years of Equivalent-Service  with0.00018% Bottle failures per year--for every 185,000 Mitsubishi Vacuum Breakers in service, only one will have a bottle fail in a given year.
