• 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).

• 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).
