  • Easy and quick m ounting either on a panel or on a D IN -rail (see figure 1 -2).
  • 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).
  • Easy 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 1 0). S1 S2 L N P1 P2
