These fuses can be used in hard climatic conditions. Fuse - links with the gR characteristic are intended for the semiconductor protection in range from the highest overloading up to the short circuit currents which correspond to the rated breaking capacity of fuse - link. Fuse - links with the aR characteristic provide limited range of protection. They break all currents from a multiple of rated current up to the breaking capacity of fuse - link. Fuse - links are produced in sizes 00C and 00 in two types: s WITH BLADE CONTACTS type UBN s WITH BOLTED CONNECTIONS type UBV. Fuse - links are in accordance with the following standards: HRN EN 60269, DIN VDE 0636, ħ6*; 7 50339.
