NAL/NALF(12KV,17.5~24KV,40.5KV ) switch disconnector(licensed by ABB, manufactured by Wuxi Lanhong Electric Co., Ltd.
NAL switch disconnector (comply with IEC 60265-1:1997 GB3804-1990)
NALF fuse switch disconnector-fuse composite apparatus (comply with IEC60420:1990 GB16926-1997)
Both NAL switch disconnector and NALF fuse switch disconnector-fuse composite apparatus which combine air-compression type and air-generation type to extinguish arc are designed by ABB with 50 years’ experience.
So far, more than 550,000 units installed worldwide are in use.
By combining NAL switch disconnector with fuse, the fuse switch disconnector possesses both advantages. NAL switch disconnector disconnects any load currents until its rated breaking current, the fuse and its striker break any over-load current until any fuse switch disconnector’s rated short-circuit breaking current. NAL switch disconnector and NALF fuse switch disconnector are largely used as transformer switch in distribution networks, motor switch or capacitor switch.
