• Easy and quick mounting either on a panel or
on a DIN-rail (see figure 1-2).
• Protection of screw terminals using specific
sealable covers to assure always the best
safety (see figure 3).
Dimensions (mm)

• 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).
• 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).
