More and more components (Fuse-Switches, Fuse-Bases) are installed in smaller cabinets. Cabinets have a limited power acceptance and the space for installation is an important part of the total costs. The main application in energy distribution grids is the 230/400 V voltage rage. EFEN 400 V fuses with lower power dissipation are perfectly fitting to the needs of the actual applications and are also saving energy. The...
