1．General
HVD1-12(VS1-12) type indoor AC HV vacuum circuit breaker (hereinafter referred to as circuit breaker) are suitable for 12kV air-insulated indoor switchgears, used as protection and control unit of power equipment of industrial& mining enterprise. Due to the super excellence, it is especially suitable for location where requires the frequent operation of rated working current or multi breaking short circuit current.
The circuit breaker adopts the integrated design of operating mechanism and circuit breaker body, servers as not only fixed installation, but also the handcart unit through equipping with a special propelling mechanism.
