Indoor Vacuum Circuit Breaker
Description:
VS1-12 indoor permanent magnet high voltage vacuum circuit breaker is indoor switchgear for three-phase AC power system with rated voltage of 50Hz and 12kV. It is used as the protection and control unit for power grid equipment and power equipment of industrial and mining enterprises. Suitable for frequent operation or multiple breaks short circuit currents at rated operating current.
The circuit breaker adopts the integrated design of the operating mechanism and circuit breaker body, which can be used as a fixed installation unit or equipped with a special propulsion mechanism to form a handcar unit.
