GENERAL DESCRIPTION
COMPONENTS
The Toshiba HCV-1JB and HCV-1KA vacuum
contactors described in this manual are suitable
for use on systems of 1.5kV, 600A and 1.5kV,
720A respectively.
Arc interruption is accomplished inside sealed
vacuum interrupters mounted on track-resistant
insulators. Vacuum interrupters use low-surge
contact materials, which exhibit low current
chopping levels reducing switching overvoltage.
