ZN63A(VS1)-12 series of  indoor vacuum circuit breaker is used for indoor 12kv switchgear,it is suitable to control and protect transmission and distribution system such as electric network equipment and industrial&minning industry etc as their protection and control unit.
It can match with KYN28(GZS1),XGN and GG1-A series of switchgears.The products meet standards of GB1984-2003,this seriesof products include:VCB truck,isolation truck and fuse truck etc.
1.This series of VCB is used integrated design for operating mechanism and VCB body with reasonable,beautiful and compact arrangement.
2.This series of VCB adopted vertical insulation house against impact due to different weather,it can effectively prevent VIS against damage by exterior factors.
3.With two kinds of installation unit:fixed type and withdrawable type,it can meet different assembling requirements between switchgear and breaker.

Applying ambient conditions
1.Ambient temperature:-10ºC~+40ºC.
2.The height above sea level:≤1000m(besides the special requirements).
3.Relative humidity:the average humidity of a day should be no more than 95%;the average humidity of a month should be no more than 90%.
4.Saturated vapour pressure:the average pressure of a day should be no more than 2.2kPa;the average pressure of a month should be no more than 1.8kPa.
5.Earthquake intensity:not exceed 8 degrees.
6.It should be installed in the places without fire,explosion,serious filth,chemical erosion and violent vibration.
