Surge Arresters – Type 2 for PV Systems

DEHNguard modular YPV ... FM
Multipole photovoltaic arresters
• Prewired complete unit for photovoltaic systems consisting
of a base part and plug-in protection modules
• Fault-resistant Y circuit with three heavy-duty varistors
prevents damage to the surge protective device in case
of insulation faults in the generator circuit
• Tested to EN 50539-11
• High reliability due to “Thermo Dynamic Control” disconnector
• Fault indication by red indicator flag in the inspection window
• Suitable for use in accordance with IEC 60364-7-712
[Photovoltaic (PV) power systems]

For protecting low-voltage consumer installations against surges. For use in accord-
ance with IEC 60364-7-712 [photovoltaic (PV) power systems].
