For protecting low -voltage consumer´s installations against surges, even
in case of direct l ight ning strokes. For use according t o the lig htning pro-
tection zones concept at bo undaries 0A – 2.
Wit h the function al design of t he new Red/Line series, the devices of the
modular DEHNventil family combine safety and innovation in an impres-
sive way. Being an ” a l l - in-one device” they assume l ightn ing equipoten-
tial bond ing and surge protection in only on e stage. Especially for use in
compact electr ical installations, this function is of advantage. The design
of t he surge arresters according to energy-coordination criteria allow s forprotect ion of even terminal devices at shor t d istances between
DEHNventil and t he consumers ( 5 m). Considering the lightning current
discharge capacity up to 100 00 0 A, this is a safe basis for high availabil-
ity of the electr ical installation t o be protected. Even for expanded electr i-
cal installations, the mo dular DEHNventil devices provide various applica-
tion possibil it ies. Red/Line surge arresters installed at th e boundaries of
the individual l ightning protection zones are already energy-coordinated
w ith DEHNventil devices. Encapsulated creepage discharge spark gaps
and the small space required by the combined light ning current and surge
arresters allow fo r easy integration int o swit chgear installation s or distr i-
bution b oards. A special feature of the new m odular Red/Line product
fami ly is the funct ional design. An important component is the module
releasing butt on. It f ixes the protection mod ule reliably to keep the safe
connection to the base part even in case of maximu m loads. If protectionmodu les have to be replaced, it releases the module w ithout requir ing
tools and allow s to remove it easily. By using the doub le terminals avail-
able for all conductor connections, the surge arresters can be connected
in series in a space-saving and cost-effective w ay up t o nom inal currents
of 125 A, as preferred by IEC 60364-5-53. For connecting further DINrail
mountable devices, busbars type
MVS 3 8 6 and MVS 4 11 8 can be
used. The right DEHNventil d evices
can be easily chosen according to
the system configuration of the
exist ing low-vol tage consumer´sinstallation and type designation of
the device.
Using the patented RADAX Flow
technology for follow current l imi-
tation and extinction achieves high
availabil ity of the electr ical installation t o be protected. Even for high
short-circuit currents up to 50 kA rm s, upcoming mains fo l low currents are
reduced in such a w ay that there is a selectivity to small fuse values, i.e.
upstream fuses cannot tr ip due t o arising mains follow currents.
The operating state/fault indicator of each protective circuit, w hich is not
supplied by operating currents, inform s imm ediately about the operating
state of the surge arrester. Apart from the standard visual indicator wit hgreen and red marks, types DEHNventil M ... FM h ave a 3-pole terminal
for remote signall ing. With t he remot e signall ing contact being a f loating
changeover contact, the remot e signal can be used as a break or make
contact, according to circuit concept.

DV MOD NPE 100: 100 kA N-PE Spark-gap-based pro tect ion module
For prot ecting low -voltage consumer ś installations against surges even
in case of direct l ight ning strokes. For use according t o the lig htning pro-
tection zones concept at bo undaries 0A – 2.
The spark-gap-based protection modules of the modular DEHNventil
series combin e safety and innovat ion in an im pressive way. Apart from the
encapsulated RADAX Flow spark gap technology, the compact protection
components include the complete monitoring circuit for controll ing the
energy flow of t he spark gap, as well as the monit oring device and oper-
ating state/fault indication.
The mechanical coding of the protection module prevents any unintend-
ed confusing of the N-PE protection modules with the spark-gap-based
modu le for the phase conductors.
The modu le locking device ensures a safe f ixing of t he protection m odules
in the base part. The module releasing butt on allow s to remove the pro-
tection modules easily without tools.

The DEHNventil ZP combined lightning current and surge arrester is an
SPD especially designed for busbar panels of supply meters. It can be
snapped directly onto busbar systems witho ut to ols.The small installation
width leaves enough space for connecting cables from the service
entrance box (SEB), even if three selective main circuit breakers are
installed.
The operating state of the SPD is reported by a l ight indicator which is
contro l led by a but ton. Both w ith th is k ind of operat ing state contro l and
due to its design as an on ly spark-gap-based SPD, DEHNventil ZP is free
of leakage and op erating currents.
The RADAX Flow spark gap technology applied allows for the requiredselectivity on follow currents even for small-sized fuses in the SEB.
Unwanted interruptions of the power supply due to tr ipping mains fuses
are thus avoided.
The rating of the parameters as well as the complete concept of the
device fulf i l entirely the require-
ments of the new German VDN*
Directive on use of surge protective
devices in prim ary pow er supply sys-
tems.
