• Easy w ay to open and close the C T core by the dedicate seleable screw s (see figure 1 ).
• 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 2 ).
• Easy output and earth connection (see fig. 3).
• 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 4 ).
• Screw term inals com patible w ith any kind of w ire term inals and protection of screw term inals using specific sealable covers to assure alw ays the best safety (see figure 5- 6-7-8).
