Table 1 - Electrical characteristics of switch-disconnectors (2P, 3P, 4P).
For frequencies > 100Hz the rated current is declassed to 25%. ( PER INGLESE )
Technical data of external earth terminal
The threaded hole to be used in order to connect the enclosure to the earth conductor is found on an external wall; use a screw
and a pre-isolated wire terminals and anti-rotation bracket supplied with the device as shown in figure 5, connection section and
tightening torque see Table 2.
