• Easy way to open and close the CT core by
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).
