HJDW1-0.5 Knife-fuse Switch-Low-voltage Knife-fuse Switch
I. Application
The JDW1-0.5 outdoor low-voltage knife-fuse switch is suitable for AC 50Hz, rated working voltage 0.5kV distribution lines, serving as short-circuit protection and overload protection for the low-voltage side of transformers. Under certain conditions, it can switch no-load transformers, no-load lines, and rated working current.
II. Technical Parameters This HJDW1-0.5 knife-fuse switch is one of the commonly used protection devices in low-voltage distribution systems.
