Type 2 Surge Arresters
• High discharge capacity due to heavy-duty zinc
oxide varistor
• Quick response
• High reliability due to "Thermo Dynamic
Control" disconnector
• Fault indication by red indicator flag in the
inspection window
• Specifically designed for high system voltages
DEHNguard ® 1000 (FM)
Compact single-pole 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.
DEHNguard 1000:
DEHNguard ... FM:
Compact single-pole surge arrester with a rated voltage U C = 1000 V a.c.
With remote signalling contact for monitoring device (floating changeover contact)
With rated voltages up to 1000 V, the compact and powerful DEHNguard
1000 (FM) single-pole surge arresters can be used for a wide range of
applications.
The DEHNguard family is not only characterised by its high degree of
flexibility, but also by its distinctive performance parameters which set
standards worldwide: The high discharge capacity, low voltage protection
level and dual "Thermo Dynamic Control" monitoring and disconnection
device stand for maximum reliability.
The external design of the device reflects its field of application.
DEHNguard 1000 (FM), with a width of two modules, entirely fulfils all
mechanical requirements resulting from the high system voltages.
Apart from the standard visual indication with green and red indicator
flags, DEHNguard 1000 (FM) arresters feature 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.
Surge Arresters Type 2
It is the DEHN-specific "Thermo Dynamic Control" disconnector that
ensures that the arresters change into a safe, isolated state even in case of
extreme overload. For this purpose, the surface temperature of the heavyduty
varistor and the intensity of the discharge current is evaluated.
Earthing brackets of type EB DG 1000 1 3 and EB 1 4 9 can be used to
connect earth terminals of several DEHNguard 1000 (FM) surge arresters
to earth.
