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 50 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

• Before working on power cables, ensure that
they are de-energised and secure them against
unintentional switch-on!
• Do not carry out mounting work during a storm!
• Comply with national laws and standards, e.g.
VDE 0100-534 (IEC 60364-5-53)!

The device can be installed in any position (e.g.
vertical or horizontal).
Figure : VDE 0100-534 (IEC 60364-5-53)
specifies that,
– in the case of single-branch wiring,
connection length a + b
– or, in the case of V wiring,
length c
should never exceed 0.5 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!
• Clamp the protection device onto the hat rail,
