Description
VS1-12(ZN63A) indoor permanent magnet high voltage vacuum circuit breaker is an indoor switchgear for three-phase AC power system with rated voltage of 50Hz and 12kV. It is used as the protection and controlunit for power grid equipment and power equipment of industrial and mining enterprises.Suitable for frequent operation or multiple break short circuit current at rated operating current. The circuit breaker adopts the integrated design of 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.
