Benefits 1 2 3 4 5 6 7 8 Easy way to open and close the CT core by Dimensions (mm) the dedicate seleable screws (see figure 1). Bridging of current transformer output without changing the connection of the secondary, so to avoid any output overvoltage during either the maintenance or the installation procedure (see figure 2). Easy output and earth connection (see fig. 3). Multiple screws provided with isolation cap screws to grant a strong and reliable fixing of the current transformer to the bus-bar (see figure 4). Screw terminals compatible with any kind of wire terminals and protection of screw terminals using specific sealable covers to assure always the best safety (see figure 5-6-7-8).
