The FLN36/48-12D/T630-25 indoor AC high voltage SF6 load switch and FLRN36/48-12D/T1250-31.5 indoor AC high voltage SF6 load switch fuse combination apparatus are designed for three-phase 50Hz ring networks or terminal power supplies. They are ideal for protecting 10kV Electric Power Load Control Systems.
The load switch can handle load current, closed-loop current, no-load transformer, and cable charging current. The combined apparatus can break any current up to the rated short circuit level, making it suitable for ring network units, box-type substations, and more.
This product is particularly well-suited for urban residential areas, small substations, opening and closing stations, industrial and mining enterprises, large shopping malls, airports, subways, hospitals, stadiums, and similar locations.
