TFN5-12DR series
Indoor high voltage load switch-fuse combination
Outline
TFN5-12DR type indoor AC high-voltage load switch-fuse combination has the advantages of small volume and light weight. It can be used in ring cabinets and box-type substations. It is widely used in the distribution of electric energy on 12KV lines, and effectively avoids the lack of phase in the equipment.
