JDW1-0.5 outdoor low-voltage knife melting switchDetailed product description：

One purpose
The JDW1-0.5 outdoor low-voltage knife melting switch is suitable for use in distribution lines with an AC frequency of 50Hz and a rated working voltage of 0.5KV. It serves as a short-circuit protection and overload protection for the low-voltage side of transformers, and can meet the requirements of no-load transformers, no-load lines, and rated working currents under certain conditions
