• 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).

(*) A max overload of 120% for 1 min. every 30 min. is allowed.

(+) A continuous overload of 120% of the range is allowed @ amb.

temp. 40°C max.
