aM Cylindrical fuse links

Industrial cylindrical fuse links

Cylindrical industrial aM class fuse links are intended for short-circuit protection in motors, transformers and other loads with high inrush currents. Provide excellent protection of switchgear (contactors, thermal switch, etc) due to good current limiting capability and low I²t values. These fuse links must be associated with an overload device protection as a thermal switch or equivalent.

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.

Manufactured with ceramic body with high withstand to internal pressure and thermal shock, that allow a high breaking capacity. Special design in the silver plated melting elements that avoid aging and maintain the characteristics along the time. Contacts made in silver plated copper.
