The cylindrical fuse-link aM, designed with a size of 14x51 and rated for 500VAC at 4A, is tailored for electrical distribution circuit protection and various industrial applications. This fuse-link features a ceramic body and silver-plated contacts, ensuring high reliability in performance.

These fuse-links are effective in safeguarding electrical devices against destructive high short-circuit currents. They are engineered to cut off currents exceeding 6.3 times the nominal current until reaching the rated breaking capacity of 120 kA. The aM type is particularly utilized for the protection of installation switch gear in motor circuit currents, allowing for the selection of nominal current in accordance with motor specifications. This unit also includes a striker to activate an auxiliary contact, enhancing its functionality in monitoring applications.
