The cylindrical fuse-link aM, with dimensions of 22.2x58 mm, is rated for 50 amperes at a voltage of 690VAC. These fuses are specifically engineered for safeguarding electrical distribution circuits and various industrial applications. They are constructed with ceramic bodies and silver-plated contacts, ensuring durability and effective conductivity.

This fuse-link type is categorized as a partial range fuse, designed to protect electrical devices from damage due to excessive short-circuit currents. It operates by cutting off currents exceeding 6.3 times the nominal current, up to its rated breaking capacity of 120 kA. The aM fuse-links are particularly suitable for use in motor circuit protection, where the nominal current of the fuse can be selected according to the motor's requirements.

With a power dissipation of 3.6 watts at rated current, these fuse-links combine efficiency with reliability. The cylindrical shape allows for easy installation via a clip mounting system, making them an integral component in electrical safety systems.
