Solar PV Fuse Type Disconnecting Switch
Fuse Type Disconnecting Switch
Fuse-switch Disconnector is applied to under Rated Voltage 690V. The main current is 16A to 630A.It is mainly used as power switch, isolator switch and emergency switch in power system.With CE certificate and test report.
The switch is consist of base and handle,three phase horizontal design.Operation type is manual front-side,suit for NH fuse ,what’s more u can observe the fuse data and operation condition via the transparent cover.
Construction of Fuse-switch disconnector is compact and modern appearance and more safe in operation.It is widely application in power grid,construction industry,Industrial control and new energy…etc.
