Product description

Surge protective device for equipotential bonding
of power supply systems according to VDE 0100-
443 (IEC 60364-4-44). For mounting on hat rails
and use in distributor housings. Arresters (Figure
) can be connected individually and are en-
1
coded on the rear side, in order to avoid incorrect
connection. They possess a thermodynamic cut-
off unit and have an arresting capacity of up to 40
kA (8/20) per pole.
If there is an error, the visual display switches
from green (grey) to red (Figure
With snap-on hat rail bracket (Figure
The spark gap C20-0-255 is intended as an ar-
rester between the neutral conductor N and the
protective conductor (PE conductor).
Only V20-..+FS..: With module for remote sig-
nalling through potential-free changeover contact
(Figure ).
