VS1-12 indoor high voltage vacuum circuit breaker is the indoor switchgear of three-phase
AC power system with rated voltage of 50Hz and 12kV. It is used as the protection and control unit of power grid equipment andpower equipment of industrial and mining industry.
Suitable for frequent operation under rated working current, or more switching short circuit current.
Circuit breaker adopts vibration mechanism and circuit breaker body integrated design.
It can be used as a fixed installation unit, or equipped with a special propulsion mechanism to form a hand car unit
