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
1
) can be connected
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
2
).
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.
General safety information
• 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 (HD 60364-5-534)!
Mounting and installation
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,
1
the total
connection length a + b
– or, in the case of V wiring,
2
the connection
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!

EN
• Clamp the protection device onto the hat rail,
ensuring that the lockable hat rail holder is un-
locked (Figure
2
).
• Maintain the stripping length and tightening
torque (Figure ).
• Connection according to the circuit diagram
(TN-C systems) or (TN-S / TT systems).
Dismantling
Figure :
• Unlock and remove arresters in the manner
shown.
• Open the hat rail holder with a flat screwdriver
and engage it (see also Figure
2
). Remove
the protection devices.
Faults
If the integrated cut-off unit trips (e.g. due to age
on account of multiple, very high overvoltages),
the visual display (Figure ) switches from grey
to red. In this case, remove the arrester and in-
sert a new arrester (available separately, V50:
item no. 5093 508, C50: item no. 5095 609). In
the case of devices with multiple arresters, it
must be assumed that the other arresters of this
device have experienced the same load. We rec-
ommend that you check them and, if necessary,
also replace them. Dispose of replaced arrest-
ers.
Remote signalling
Figure (only V50-..+FS..):
When at least one arrester is disconnected, the
changeover contact in the remote signalling mod-
ule switches from 11/12 to 11/14. Remote signal-
ling can be switched as an NO or NC contact.
This allows control of suitable signalling compo-
nents (e.g. central error messages, light or
acoustic signal).
• Connect the remote signalling cables as
shown, in so doing maintaining the specified
cable cross-section and the stripping length.
Maintenance
We recommend carrying out a visual check of
the visual display every 2-4 years or after light-
ning strikes.
Disposal
– Packaging as household waste
– Protection device/arrester as electronic waste.
Comply with the local waste disposal regulations.
