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 firing pin to trigger an auxiliary contact. All cylindrical fuse links consist of a ceramic body and silver-plated contacts. Cylindrical fuse links of operating class aM are partial range fuses and protect electrical devices from destruction in the event of impermissibly high short circuits due to their strong current limitation and low thermal conductivity. They switch off currents that are greater than 6.3xln up to the maximum breaking capacity. Cylindrical fuse links aM are preferably used to protect systems and switching devices in motor circuits. When assigning the fuse links, the fuse nominal current can be selected to be equal to the motor nominal current. Our technology and manufacturing process ensure highly reliable technical performance.
