GENERAL DESCRIPTION
COMPONENTS
The Toshiba CV-1GAU and CV-1HAU vacuum
contactors described in this manual are suitable
for use on systems of 1.5kV, 160A and 1.5kV,
320A 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.
This manual covers several models of typeforms
of CV-1GAU and CV-1HAU vacuum contactor.
Included are the basic GAU and HAU models
as well as the GAU-P2, HAU-P2, GAUMIL,
HAUMIL, GAU-C and HAU-C.
-P2 models have a fast opening time.
-MIL models are for mechanical interlocking.
-C models have a 480-550Vcontrol voltage.
