Surge Arresters – Type 2

DEHNguard SE H ... FM
• Universal surge arrester comprising a base part and a plug-in
protection module
• Energy coordination with other arresters of the Red/Line
product family
• High discharge capacity
• High reliability due to "Thermo Dynamic Control" SPD
monitoring device
• Easy replacement of protection modules without tools due
to module locking system with module release button

Single-pole surge arrester for protecting low-voltage consumer installations from
surges. For installation in conformity with the lightning protection zone concept at
the boundaries from 0B – 1 and higher.

DEHNguard SE H 1000 FM: Pluggable single-pole surge arrester with a high discharge capacity comprising a base part and a plug-in protec-
tion module; with remote signalling contact for monitoring unit (floating changeover contact)
DEHNguard SE H 1000 VA FM: Pluggable single-pole surge arrester with a high discharge capacity and a varistor connected in series with a
spark gap comprising a base part and a plug-in protection module; with remote signalling contact for monitoring
unit (floating changeover contact)
