RADAX Flow fol low current l imitation• No tr ipping of 20 A gL/gG fuses up to

• Al low s for easy replacing of protect ionmodules due to module locking systemw ith releasing button

• Tested for v ibrat ion- and shock-proof-ness according to EN 60068-2

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.

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.

For prot ecting low -voltage consumer ś installations against surges even



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.
