CZFSD Series Outdoor Fuse Isolation Switch - China Suppliers and Factory for 160A, 400A, 630A, AC 220V to 690V Solutions
Products Description
CZFSD fuse switch Disconnectors provide safe controlled disconnection of electrical power to individual users and power units in combination with short circuit devices, that allows safe main-tenance intervention by protecting against short circuit and earth current leakage.
The fuse switch Disconnectors consist of a glass fibre reinforced plastic housing and a dismountable switch flap which contains the fuses. The base body carries the connecting terminals which connects the fuse contacts. Arc suppressing chambers above the fuse contacts limit and quench the power arc that may occur during switching, preventing thermal overload of the fuse switch connector. Both aluminium and copper conductors can be connected to the disconnector.
The switch flaps are equipped with fuse holders suitable for NH fuse inserts, disconnecting links or short-circuit devices.
