DNH18 vertical fuse switch disconnector is installed with a special hanging terminal and directly connected to the busbar. The hanging terminal can be fixed on the switch in advance and installed integrally with switch efficiently and conveniently. It comply with the national standard GB/T 13539.2 and GB/T 14048.3 and the International Electrotechnical Commission standard IEC 60947-1 and IEC 60947-3.
The DNH18 vertical fuse switch disconnector can provide a variety of wiring modes to meet your wiring needs in different situations.
Fuse switch disconnectors are widely used in power grids, industrial power control, new energy and other fields.
In power system, it is widely applied in feeder pillar, integrated distribution panels, GGD low-voltage power distribution cabinets, capacitor compensation cabinets,etc.. In the field of industrial control, it is widely used in photovoltaic equipment, industrial electric furnaces, industrial control cabinets of automobile manufacturing and other industries. In new energy industry, it is generally applied in combiner boxes and grid-connected cabinets,etc..
The fuse switch disconnector not only is suitable for electrical professionals to manage and maintain the power distribution mains and power branch lines , but also for non-professional electrical personnel.Because people only can change the fuse after pulling the handle out and under off grid.
