FZW28F-12 series outdoor boundary vacuum load switchDetailed product description：

The FZW28F-12 series outdoor boundary vacuum load switch is suitable for outdoor three-phase AC distribution systems with a rated voltage of 12kV and a rated frequency of 50Hz. It is used for opening and closing load currents and closing short-circuit currents.
Suitable for substations, industrial and mining enterprises, as well as urban and rural power grid protection cities, agricultural power grid automation distribution networks, and places with frequent operations.

The FZW28F-12 series outdoor boundary vacuum load switch consists of two main parts: the FZW28-12 vacuum load switch and the controller, which are electrically connected through aviation sockets and outdoor sealed control cables. It can reliably determine the zero sequence current and phase to phase breaking current of milliampere inside and outside the detection boundary, and is suitable for distribution systems with different neutral grounding methods.
