Type 2 Surge Arresters
• Specifically designed for use in "3+1" and
"1+1" circuits of TT systems acc. to IEC 60364-
5-53 between neutral conductor N and protective
conductor PE
• High discharge capacity
• Two-part surge arrester consisting of a base
part and a pluggable spark-gap-based protection
module
• Energy coordination with other arresters of the
Red/Line product family
• Operating state/fault indication by indicator
flag in the inspection window
• With remote signalling contact for SPD monitoring
device
• Easy replacement of protection modules without
tools due to module locking system with
module release button
• Vibration and shock-tested according to
EN 60068-2
DEHNgap C S
N-PE surge arrester
For protecting low-voltage consumer’s installations against surges. For
installation in conformity with the lightning protection zones concept at
the boundaries from 0 B – 1 and higher.
DEHNgap C S:
DEHNgap C S FM:
N-PE surge arrester consisting of a base part and plug-in protection module
With remote signalling contact for monitoring device (floating changeover contact)
The N-PE surge arresters of type DEHNgap C S are an ideal supplement
to the single-pole DEHNguard S surge protective devices. Being total current
arresters between the neutral and protective conductor in TT systems,
DEHNgap C S surge arresters help to ensure fulfilling the requirements
for protection of personnel and equipment in "3+1" and "1+1"
circuits.
Safety of DEHNgap C S surge arresters is increased by monitoring the
arrester temperature and an integrated disconnector connected in series
with the surge arrester.
The green and red indicator flags show the operating state of DEHNgap
C S surge arresters.
Surge Arresters Type 2
With their modern Red/Line design, DEHNgap C S surge arresters have
exactly the same user-friendly safety features as the DEHNguard S
devices. The unique module locking system combines the spark-gapbased
protection module and the base part to a powerful unit. Neither
vibration during transport nor the enormous electromagnetic forces of
discharge can loosen this connection. Nevertheless, the protection modules
can be easily replaced without tools by simply pressing the userfriendly
module release button of the protection module. The mechanical
coding of protection module and base part ensures against installing an
incorrect module.
Apart from this standard visual indication, DEHNgap C S ... FM features
a three-pole remote signalling terminal. With its floating changeover
contact, the remote signal can be used as a break or make contact
according to the particular circuit concept. The N-PE surge arresters of
type DEHNgap C S incorporate multifunctional terminals for connecting
conductors and busbars, allowing easy wiring with other DIN rail mounted
devices. Thus, a variety of applications can be easily connected in
series according to IEC 60364-5-53 for optimal protection.
