CZFSD Series Outdoor Fuse Isolation Switch

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.

High-performance device designed for outdoor power systems and is widely used in power distribution and protection. The switch adopts a hanging design, which is easy to install on outdoor power poles to ensure stable operation under various climatic conditions. Its modular design makes maintenance and replacement more convenient. Users can choose different current levels according to actual needs, including 160A, 400A and 630A, to meet various load requirements. This series of products supports a voltage range of AC 220V to 690V, which can meet the application requirements of different voltage levels. 

The CZFSD series is perfectly matched with the low-voltage HRC NH series fuse, providing reliable overload and short-circuit protection to ensure the safety and stability of the power system. Whether in urban power grids or rural power facilities, the CZFSD series is an ideal choice to help efficient and safe power transmission.
