Surge Arresters – Type 2

DEHNcord
• Single-pole, two-pole or three-pole surge protective device
with monitoring system and disconnector
• Visual fault indication
• Types with disconnection of the load circuit in the event
of a fault and protection of the control phase
• Compact design also for outdoor use
• Can be fitted in junction boxes, flush-mounted systems,
cable ducts and flush-type boxes

For protecting electronic devices (e.g. LED lights, smart poles, wall boxes or techni-
cal building equipment) from surges. For flexible installation in electrical installa-
tion systems such as flush-type boxes. Due to its compact design, the arrester can
always be installed in the right place in the relevant installation area. For instal-
lation in conformity with the lightning protection zone concept at the boundaries
from 0B – 1 and higher.

DEHNcord L 1P …: Compact single-pole version; e.g. for use in luminaires of protection class 1
DEHNcord L 2P …: Compact two-pole version; e.g. for use in luminaires of protection class 2 or in flush-type boxes,
flush-mounted systems and cable ducts
DEHNcord L 3P … SO LTG: Compact three-pole version; for use in the junction boxes of LED light poles with disconnection
of the load circuit in the event of a fault and for protecting the control phase

DEHNcord R 3P …: Compact three-pole version; for use with electric sun shading systems
DEHNcord 3P ...: Compact three-phase version; for use in confined spaces, e.g. in a wall box

The DEHNcord series can be used flexibly as a type 2 surge arrester, thus LED lights are optimally protected against
