• E asy and quick m ounting on a panel (see figure 1).
• Protection of screw term inals using specific sealable covers to assure alw ays the best safety (see figure 3 ).
• B ridging of current transform er output w ithout changing the connection of the secondary, so to avoid any output overvoltage during either the m aintenance or the installation procedure (see figure 4).
• E asy output and earth connection (see fig. 5 ).
• Screw term inals com patible w ith any kind of w ire term inals (see figure 6-7-8-9).
• M ultiple screw s provided w ith isolation cap screw s to grant a strong and reliable fixing of the current transform er to the bus-bar (see figure 10).
