The fuse-lins fo industrial and similar applications, consist of body in steatite and can tolerate very high thermical changes, which occur inside of iit at the cut off time. The fusing element consists. Of a silver-plated copper foil. The quartz-sand
allowes to avoid the arcpropagation, 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, IEC269.1.3.3A NFC 61.210.201 UNE 21.103
