aM Cylindrical fuse links
aM Class Cylindrical fuse links are intended for short circuit protection in motors, transformer and other load with high inrush currents. Excellent protection of switchgear (contactor, thermal switch) due to the good current limiting capability and low I2t values. These fuse links must be associated to an overload device protection as a thermal switch. Made of ceramic tube with high withstand to internal pressure and thermal shock, that allow a high breaking capacity in a reduced physical space. The melting elements are silver plated in order to avoid the aging and thus keep unalterable the electric characteristics. Contacts caps are made of silver plated copper. Available versions with fusing indicator or with striker for use in fuse holders with microswitch.
The range comprises fuse-links of sizes 8×32, 10×38, 14×51 and 22×58 with rated currents comprises between 0,16A and 125A. Available in standard version and with visual fusing indicator. For sizes 14×51 and 22×58 also available in striker version intended for use in fuse holders with microswitch.
