FZW28-12 Outdoor Boundary Vacuum Load Switch

Overview
The FZW28-12 series outdoor 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 clothing network protection cities, agricultural network automation distribution networks, and places with frequent operations.
The boundary load switch is operated by FZW28-12 vacuumHigh voltage load switchComposed of two main parts, the controller is 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 can adapt to distribution systems with different neutral grounding methods.
