Product description
Lightning current and surge protection device for
equipotential bonding of power supply systems
according to VDE 0100-443 (IEC 60364-4-44)
and for lightning protection equipotential bonding
according to VDE 0185-305 (IEC 62305). For
mounting on hat rails and use in distributor hous-
ings. Arresters (Figure
individually and are encoded on the rear side, in
order to avoid incorrect connection. They pos-
sess a thermodynamic cut-off unit and have an
arresting capacity of up to 40 kA (8/20) and
12.5 kA (10/350) per pole.
If there is an error, the visual display switches
from grey to red (Figure ).
With snap-on hat rail bracket (Figure
The spark gap C50-0-255 is intended as an ar-
rester between the neutral conductor N and the
protective conductor (PE conductor).
Only V50-..+FS..: With module for remote sig-
nalling through potential-free changeover contact
(Figure ).
Target group
The device may only be mounted and connected
by an electrical technician.

The device can be installed in any position (e.g.
vertical or horizontal).
Figure : VDE 0100-534 (HD 60364-5-534)
specifies that,
– in the case of single-branch wiring,
connection length a + b
– or, in the case of V wiring,
length c
should ideally not exceed 0.5 m, but never ex-
ceed 1.0 m.
For V wiring, use the connection terminal, item
no. 5012 010.
Caution! Risk of overloading!
The connection terminal 5012 010 is
approved for a maximum current load ≤
50 A.
Use a suitable back-up fuse!
