Surge Arresters – Type 2

DEHNguard S
• Multi-purpose surge arrester consisting of a base part and a
plug-in protection module
• High discharge capacity due to heavy-duty zinc oxide varistor
• High reliability due to "Thermo Dynamic Control" SPD
monitoring device
• Energy coordination with other arresters of the Red/Line
product family
• Operating state / fault indication by green / red indicator flag
in the inspection window
• Narrow (modular) design acc. to DIN 43880
• Multifunctional terminals for connecting conductors and
busbars
• Easy replacement of protection modules due to module
locking system with module release button For protecting low-voltage consumer installations against surges. For installation
• Vibration and shock-tested according to EN 60068-2 in conformity with the lightning protection zone concept at the boundaries from
0B – 1 and higher.
