Wiring Diagram

• Easy and quick mounting on a panel (see

figure 1).

• 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).
