In the TN-S mains supply system, lightning arresters
of requirement class B (broad-based protection) are
used in the 3+1 circuit. In the 3+1 circuit, the incoming supply lines are connected via arresters to the

due to the insulation problems that may occur with
leakage currents.

Lightning arrester LightningController MC 50-B VDE
LightningController MC 50-B VDE is a plug-in multiple
spark gap. The device consists of nine partial spark
gaps, formed by ten heavy-duty carbon discs. The
precisely defined spacing of the spark gaps is safely
ensured by highly heat-resistant Teflon discs. Blade
contacts of pressure die-cast zinc, which are screwed
to each other, clamp the spark gap together with
accurate positioning. Eight of the nine spark gaps are
capacitively controlled and thus ensure a precisely
defined operating surge voltage of ≤ 2 kV.
The lightning arrester conforms to requirement class B
to DIN VDE 0675 Part 6 (Draft 11.89) A1, A2 and
class I to IEC 61643-1 (02.98). The device is
designed to be used between interface 0 to 1 in
accordance with the lightning protection zone concept of IEC 61312-1.
In a lightning protection installation in a building,
LightningController MC 50-B VDE provides lightning
protection potential equalisation with the power supply lines. The device has been successfully tested
with respect to the lightning current parameters
according to ENV 61024-1 and IEC 61024-1.

Since the protective action of LightningController
MC 50-B VDE is ensured even with a direct lightning
strike on an overhead line, the device can also be
used in buildings supplied with power via an overhead line.

Block diagram of LightningController
Mounting
LightningController MC 50-B VDE is easy to install,
since the dimensions of the housing of the device
conform to the space-saving 17.5 mm grid module.
The lightning arrester is installed simply by snapfitting it to the top-hat rail. The LightningController has
two terminals each for the N and PE-conductors.
Note: since the spark gap of the device is enclosed,
no plasma arcs are produced outside the casing.

LightningController MC 125-B/NPE was designed to
be used in TN-S, TT and IT systems as a sum current
spark gap between the neutral conductor (N) and the
protective earth conductor (PE). At the heart of the
device there are two partial spark gaps made up of
three carbon discs which can handle heavy loads.
The precisely defined spacing of the spark gaps is
ensured by highly heat-resistant Teflon discs.
The lightning arrester satisfies the preconditions of
requirement class B to DIN VDE 0675 Part 6 (Draft

the surge arrester (requirement class C) with compact
TT and TN-S systems can be omitted.
Coordinated LightningControllers MCD 50-B and MCD
125-B/NPE are lightning arresters of requirement class
B to DIN VDE 0675 Part 6 (Draft 11.89) A1, A2, and
Class I to IEC 61643-1 (08.98). In combination with
surge arresters connected directly after them, they
ensure coordinated operation. No additional decoupling components are needed. The fundamental advantages of the innovative multi-carbon technology of
OBO LightningControllers are fully preserved.
Mounting
The low protection level (Up ≤ 1.3 kV) makes it unnecessary to install decoupling inductances or to provide
additional lengths of conductor between lightning
arresters (requirement class B) and surge arresters
(requirement class C). The result is up to 45 percent
space saving on installation. And this proves to be a
particular advantage, especially with compact EMC
concepts. In addition, the separate NPE spark gap at
Coordinated LightningControllers are suitable for
snap-fitting to standard commercial 35 mm top-hat
rails to DIN EN 50022 and conform to the
space-saving 17.5 mm grid module. At each connection point there are two possibilities for Lx and N/PE.
Note: Since the arrester elements of the devices are
enclosed, no plasma arcs are produced outside the
casing.

Surge protection devices of requirement class B in
main power supply systems (upstream of the meter)
If a lightning arrester of requirement class B is to be
installed, it must be installed in accordance with the
lightning protection zone concept to DIN VDE 0185
Part 103 in the region of lightning protection zone 0 to
1. In most cases the arrester is installed where the
power lines enter the building.
If the meter is not located directly at lightning protection zone 0 to 1, it may be necessary to install lightning arresters of requirement class B in the unmetered
region.

Preconditions
Several points must be considered when choosing
and installing arresters in the unmetered region.
The VDEW has published guidelines for the use of
surge protection devices of requirement class B in
main power supply systems (01/98).
1. Surge protection devices of requirement class B
to DIN VDE 0675 Part 6 (A1, A2) are used. They
are chosen, and their parameters are set up, in
accordance with DIN VDE 0100-534 (A1).
2. It is essential to ensure that the surge protection
device is permanently isolated from the mains in
the event of an internal short-circuit.
3. The ability of the surge protection device to carry
lightning current must conform to the regulations
26
7.
8.
in force where it is installed, in accordance with
DIN VDE 0185 Part 100. If the ability to carry lightning current is not known, it must be chosen to
suit lightning protection class I to DIN VDE
0100-534.
Only surge protection devices that are designed
as a spark gap are used. It is not permissible to
connect varistors in parallel.
The manufacturer guarantees the short-circuit
strength of the surge protection devices in accordance with TAB Section 7.2.
Voltage surge protection devices of requirement
class B must always be installed in combination
with the correctly chosen current surge protection
devices, approved by the manufacturer for this
purpose – especially housings with protection IP
54 with protective insulation.
It must be possible to lead-seal the
protectively-insulated housings of surge protection
devices in accordance with the “lead-sealing requirements” issued by the VDEW.
The surge protection devices must be checked at
least every four years to ensure that they are in
perfect condition. Electricity supply companies
may demand relevant proof.

Decoupling inductance LightningCoordinator LC 63
Operation and fields of application
If there are several surge protection devices in a network, they may influence each other, and this may
mean that the parallel arresters must be coordinated
in terms of energy. The effect of this coordination is
that, in the event of a voltage surge due to lightning,
the lightning arrester (class B) responds reliably,
diverting the high-energy currents, so protecting the
other surge arrester(s) (class C or D) from overload.
This energy coordination is provided by LightningCoordinator type LC 63. This device establishes coordination between spark-gap lightning arresters (requirement class B) and varistor-based surge arresters
(requirement class C). The LightningCoordinator also
ensures the coordination of NPE arresters of different
requirement classes.
It is only necessary to install the LightningCoordinator
if the distance between lightning arrester and surge
arrester at the zone interfaces (total line length) is not
more than five meters. Where this is the case, the
natural inductances of the conduction path are not
sufficient, and a decoupling inductance must therefore be connected between the protection devices
which operate in different ways.
Typical fields of application are compact surge
protection installations in a separate housing, and installations with arresters of requirement classes B and
C inside a distribution board.
The good commutation properties of the LightningCoordinator are due to its optimally arranged inductance. The large cross-section of the strip-shaped coil
conductor gives a low DC resistance, resulting in only
a slight temperature rise in normal operation.

Lightning/surge arresters CombiController
V 25-B+C, V 25-B+C/...+NPE
Lightning and surge arrester V 25-B+C ensures lightning protection potential equalisation in accordance
with VDE 0185, Part 1 and Part 100. The device is an
arrester of requirement Class B+C to DIN VDE 0675,
Part 6 (Draft 11.89) A1, A2. It ensures potential equalisation for the energy supply line in lightning protection installations for buildings. The arrester can also
be used in buildings that are supplied with power via
an overhead line, since direct or partial lightning currents may be expected there as well.
Version V 25-B+C/3+NPE (requirement Class B+C) is
a special surge arrester for TN-C-S, TN-S, TT and IT
systems. This device was developed for the new requirements of DIN VDE 0100, Part 534/A1, to allow
simple, safe installation of the devices.
High-performance arrester OBO V 25-B+C has a
special varistor circuit made up of powerful zinc
oxide varistors with a highly non-linear characteristic
(a>30). This design ensures maximum protection
Test marks
30
even with powerful surges. Even at a maximum load
Imax of 50 kA the protection level is below 1.5 kV. This
enables this type of device to withstand even partial
lightning currents from direct lightning strikes. In the
event of an overload, the built-in isolating device isolates the faulty arrester module from the network and
indicates this with a red field.
Because of the low residual voltage, OBO lightning
arrester V 25-B+C can also be used as a combined
arrester B and C.
Service location in accordance with VDS 2031.
Mounting
The OBO V 25-B+C can easily be installed in any distribution box or switchgear cabinet by snap-fitting to
any commercial 35 mm top-hat rail. The NPE arrester
element type C 25-B+C/NPE and the matching base
are designed so that they cannot be plugged in the
wrong way round (coding). This ensures correct installation of the upper parts of the arresters.

Surge arresters SurgeController V 20-C,
V 20-C/...+NPE
SurgeControllers V 20-C are surge arresters of requirement class C to DIN VDE 0675, Part 6
(Draft 02.89) A1, A2. These devices protect
low-voltage consumer installations from voltage surges of all kinds. They are available in single-pole to
four-pole versions.
Type V 20-C/3+NPE (requirement class C) is a special
surge arrester for TN-C-S, TN-S, TT and IT systems.
This device was developed for the new requirements
of DIN VDE 0100, Part 534/A1, to allow simple, safe
installation of the devices.
The voltage-dependent active part of the V 20-C is a
high-performance zinc oxide varistor with a highly
non-linear characteristic. Among the advantages of
this component are an extremely short response time,
a low protection level and a high current diversion
capacity, combined with long life. A further feature of
Test marks
34
these devices is that no follow-up current can be
registered after the surge has decayed.
If the surge arrester is damaged by overloading, the
integral isolating device breaks the connection to the
mains. This is signalled by a red fault indicator.
Mounting
The V 20-C can easily be installed in any distribution
box or switchgear cabinet by snap-fitting to any commercial 35 mm top-hat rail. The poles of multi-pole
arresters are connected together by an earthing
bridge at the factory, so that there is only one earth
(PE) connection to make on site. The NPE
arrester element type C 25-B+C/NPE and the matching base are designed so that they cannot be
plugged in the wrong way round (coding). This
ensures correct installation of the upper parts of the
arresters.

Signalling device for CombiController V 25-B+C/FS
and SurgeController V 20-C/FS
Operation and fields of application
Remote signalling allows central monitoring of the
serviceability of lightning arresters and surge
arresters, even when the devices cannot be observed
directly or are installed where access is difficult.
1 2 3
A monitoring module is installed at each arrester
block to provide a constant check that all the connected arresters are ready to operate. If an arrester
fails, a mechanism passes a command to the microswitch in the monitoring module. This fault signal is
then passed to the remote indicating unit, where the
fault is indicated optically or acoustically.

Acoustic signalling device for CombiController
V 25-B+C/AS and SurgeController V 20-C/AS
Operation and fields of application
230 V L1
Acoustic signalling is a safety component which permanently checks the serviceability of arresters and
indicates a fault by means of a warning tone. Constant self-checking of the arrester fitted with this monitoring module provides unbeatable safety – even without visual inspection. The device is ideal wherever
optical signalling does not appear rational or feasible.
Examples are dwelling houses, agricultural buildings,
banks, office and administration buildings, and so on.
The warning tone can be silenced for the next 24
hours by operating a black switch. When the faulty
device has been replaced, a green LED indicates that
the arrester block is working properly.

The control module starts an acoustic alarm immediately after the operation of an isolating device. The
alarm takes the form of a high-frequency warning tone
which can be heard at a considerable distance. In
addition, a red LED flashes on the monitoring module.

L3
CombiControllers and SurgeControllers used in electrical installations with main fuses rated above 160 A
and 125 A respectively are provided with their own
fuses. To ensure permanent monitoring of the surge
protection, signalling devices V 25-B+C/FS-SÜ and
V 20-C/FS-SÜ are installed.
The control module monitors all three phases of the
arrester and the serviceability of the series-connected
fuses. Any drop in the supply voltage and any fault in
a fuse, as well as tripping of an isolating device in the
arrester module, is registered immediately and indicated by remote signalling.
The duct on top of the arrester block covers the connections of the monitoring module to the three-phase
network. In this way the applied voltage is monitored.
Not only the failure of an arrester is registered, but
also the failure of a series-connected fuse.
Mounting
The standard 17.5 mm case of the V 25-B+C/FS-SÜ
and V 20-C/FS-SÜ snap-fits to a 35 mm top-hat rail.
Screwless terminals keep installation time short.

ISOLAB checking system
ISOLAB, which has been tested by the VDE, is an
insulation and arrester tester. This combination
device can be used for insulation testing of electrical
installations to DIN VDE 0100/Part 610 as well as to
determine the characteristics of the upper parts of
type V 25-B+C and V 20-C. The ISOLAB tester is also
suitable for checking the insulation performance
of LightningControllers MC 50-B/VDE and
MC 125-B/NPE.
1. Insulation measurement
Before insulation testing starts, the mains voltage
must be switched off. In other words, there must be
no voltage on any part of the installation. When the
test leads have been connected, insulation testing is

started by pressing the start button. The resistance
reading appears on the display. (Note: before insulation testing, the upper parts of arresters must be removed and other surge protection devices must be
disconnected.)
2. Arrester test
The selector switch is used to select the type of module to be tested (V 25-B or V 20-C). Plugging in the
upper part starts the test procedure automatically.
The 1 mA or 3 mA point can be read off on the display. By comparing the results with the printed tolerance field table, it is possible to tell whether the arrester has suffered ageing and needs to be replaced.
Note: test leads are supplied with the tester.

Peak Current Sensor PCS monitoring system
Operation and fields of application
Mounting
The Peak Current Sensor records and permanently
stores impulse currents on a magnetic card. The magnetic strip of the PCS is encoded in a special way.
Since every current-carrying conductor produces a
magnetic field proportional to the current, such a
magnetic field influences the encoding of the magnetic strip. This change is evaluated and displayed on a
special magnetic card reader PCS-CS. This makes it
possible to measure impulse current in lightning
protection installations and – using the test kits in the
equipotential bonding lines – in lightning and surge
arresters. In this way, the effectiveness of these
protection devices can be checked at any time.
The Peak Current Sensor is held in a card holder
which is attached to 8 or 10 mm round wire (usual in
outdoor lightning protection installations). The card
holder secures, protects and positions the magnetic
card. Special mounting kits from the OBO range are
used for simple, quick installation of the magnetic
card on equipotential bonding bars (a) and on lightning arresters in buildings (b).
Note: each magnetic card can be evaluated once at
the factory free of charge.
