Product Introduction :

The product can be used in indoor Ac system of 50Hz and rated voltage 3.6kV and 7.2kV .When used together withe other protection facilitles (such as switches and vacuum contactors),it works to protect high-voltage engines and other electric facilities from overloading and circrit break.

Major technical characteristics

1.In required working conditions,the fuse can break any problem current between the minimum break current 1.6-3 and the rated break current.
2.See chart 3 for time-current property.the section above the mimimum break current is broken line.
3.See chart 4 for current limit property.
4.See chart 5 for property.
