The components of the DNH1G Fuse Switch Disconnector
> GRL DNH1G Fuse Switch Disconnector enables safe manual connecting and disconnecting electrical circuits under load.Their main purpose is to protect electrical equipment against overload and short circuit by using fuse-links from size 00 to size 3.
> 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, 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.
