Product Features

Meiden has been a pioneer in vacuum interrupter (VI) technology since the mid-1960s, and has delivered many breakthroughs, including the world’s first high voltage VI. Today, Meiden manufactures VIs ranging from 3.3kV to 145kV, for a wide variety of applications. Meiden VIs are available at voltages of up to 145kV (single-break). Meiden’s world class engineers can also develop custom VIs for your applications.

  • High quality vacuum valve design certified according to all IEC and ANSI standards
  • Long operating life
  • Compact
  • High reliability

Video Introduction to VI

Meiden America Switchgear is a subsidiary of Meidensha Corporation. Meidensha has been producing 72.5 kV dry-air insulated vacuum circuit breakers since 2004 and has been producing vacuum interrupter bottles since 1967. Meidensha corporation was founded in 1897.


Applications and Solutions

High and Medium-Voltage VIs for Switchgear

Special contact materials and electrode designs prevent contacts from fusing. Stantard products meet of IEC and IEEE(ANSI) standards,and are compact, with high withstand voltage and heavy current breaking capabilities. Optional external insulation reinforcement is available for interrupters rated 24 kV and higher, for capacitor bank switching applications.

Specialized VIs for Electric Railway Switching

These low voltage vacuum interrupters are engineered with custom bellows to ensure high performance. Meiden’s low-voltage VIs for railway applications are capable of at least 250,000 switching operations, and can handle current up to 1300A to meet the performance demands of high-speed railway operations.

Additional Applications

Meiden has engineered a wide variety of application-specific VIs for distribution equipment, all of which meet IEC and IEEE (ANSI) standards. These applications include:

  • Switchgear
  • VCB (Live tank VCB, Dead tank VCB, etc.)
  • Load breaking switches
  • Reclosers
  • Fault interrupters
  • Contactor
  • Cap Switch
