Protection of screw terminals using specific 63 sealable covers to assure always the best 30 safety (see figure 3). 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 4). 51 Easy output and earth connection (see fig. 5). Screw terminals compatible with any kind of wire terminals (see figure 6-7-8-9). Multiple screws provided with isolation cap screws to grant a strong and reliable fixing of the current transformer to the bus-bar (see figure 10). 45 Wiring Diagram S1 S2 31 42 51 81,2 64 90 L P1 P2 N 2 Specifications are subject to change without not ice CTD-4X DS ENG 230518 51 43,5 20,5 49,9 113 131,5
