Descrizione del prodotto
The D0 fuse-system is installed in motor circuit protection, where fuse-links are accessible to non trained persons and can also be replaced by them. The system is the most modern of the screw systems and designed for 400VAC/440VAC networks. Type “aM” fuse-links are partial-range breaking capacity fuse-links, used to protect motor circuits as they are strongly current-limiting and have low power losses. They limit and cut off short circuit currents from 6.3 times In up to their nominal breaking capacity.
