The fuse-links for industrial and similar applications consist of body in steatite and can tolerate very high thermal changes, which occur inside of it at the cut off time. The fusing element consists of a silver-plated copper foil. The quartz-sand allows avoiding the arcpropagetion, keeping the fuse link at a low temperature. The double (inner and outer) caps assure the best contact; the outer part is silver-plated to avoid and oxydation and to keep unchanged the electrical in every climatic conditions. These fuse-links are manufactured according to the following International standards: CEI 32.1 and 4, IEC 269.1.3.3A, NFC 61.210.201, UNE 21.10 producing area:China
