VS1-12 indoor side-mounting AC and High-voltage VCB is a type of indoor switchgear applied to electric system of rated voltage 7.2~12kV, three-phase 50/60Hz to protect and control apparatus. It is especially appl icable in occasion
with frequent operation; it can break short- circuit continuously. This HV VCB is of fixed mounting, mainly used in stationary switch cabi net. It can work separately or in ring network power supply, prefabricated substation as well
as in non-standard power supply system.
