Medium voltage cylindrical fuse links

MV cylindrical fuse links range comprise three sizes with dimensions 10×85, 10×150 and 10x180mm, with rated currents between 2A and 12A and rated voltages of 1500 V AC, 2500 V AC, 3200V AC and 5500 V AC.

They have a g breaking range (protection against overload and short-circuits) and are made with ceramic tubes having high breaking capacity and good withstand against thermal chock. Contacts are made in silver plated copper.

One of the applications of these fuse links are the protection of supply networks of public lighting at higher voltages (between 900V and 5.500V AC) usually used by means of special transformers designed for this purpose that increase the voltage for transportation and reduce it in the destination at adequate levels. These distribution networks allow energy transportation at very high distances with installations more economic and efficient.
