Caution
Direct contact between the copper bar and aluminium wire may arise electrochemical
corrosion, thus aff ect the reliability of the electrical connection.
If an aluminium wire is used, please use a copper-aluminium wire terminal to avoid di-
rect contact between the copper bar and aluminium wire.

Note
S ≤ 16 mm² S
The specifi cations are valid only when the phase wire and PE wire
use the same material. If otherwise, ensure that the cross section of
the PE wire produces a conductance equivalent to that of the wire
specifi ed in the table.
