Product Description

FZW28-12F series outdoor demarcation vacuum load switch is suitable for outdoor three-phase AC power distribution system with rated voltage of 12kV and rated frequency of 50Hz as open and close load current and short circuit current.
It is suitable for substations, industrial and mining enterprises, cities and rural power grids as protection cities, automated distribution networks of rural power grids and places of frequent operation;
The boundary load switch is composed of FZW28-12 vacuum load switch and controller, which are electrically connected through aviation socket and outdoor sealed control cable. It can reliably judge the zero sequence current and interphase break current inside and outside the detection boundary, and can be suitable for distribution systems with different neutral ground modes.
