Surge Arresters – Type 3

DEHNrail modular
• Two-pole surge arrester consisting of a base part and a plug-in
protection module
• High discharge capacity due to heavy-duty zinc oxide
varistor / spark gap combination
• 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 according to DIN 43880
• Easy replacement of protection modules due to module
locking system with module release button
• Vibration and shock-tested according to EN 60068-2
