PRODUCT DETAILSVS1-12 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. TECHNICAL
