Surge Arresters – Type 2

DEHNguard 1000
• High discharge capacity due to heavy-duty zinc oxide varistor
• Quick response
• High reliability due to "Thermo Dynamic Control" disconnector
• Fault indication by green / red indicator flag in the inspection
window
• Specifically designed for high system voltages

For protecting low voltage consumer installations against surges. For installation
in conformity with the lightning protection zone concept at the boundaries from
0B – 1 and higher.

DEHNguard 1000: Compact single-pole surge arrester with a rated voltage UC = 1000 V a.c. or 1000 V d.c.

the arresters change into a safe, isolated state even in case of extreme
overload. For this purpose, the surface temperature of the heavy-duty
varistor and the intensity of the discharge current are used for evaluation.
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.
