Mersen aM and gG fuse links cover a wide range of different sizes and currents for 400, 500 and 690VAC. They are used to protect electrical distribution circuits and industrial systems. Most of the currents are available in sizes 8x31 and 10x38 with an optional indicator, and in sizes 14x51 and 22x58 with an optional striker to trigger an auxiliary contact. All cylindrical fuse links consist of a ceramic body and silver-plated contacts. Cylindrical fuse links of operating class gG are used to protect cables, devices and systems. They safely switch off impermissible overcurrents and short-circuit currents up to the rated breaking current. Cylindrical fuse links gG also protect electrical devices and systems from the electrodynamic effect of high short-circuit currents. Our technology and manufacturing process ensure highly reliable technical performance.
