Combined Arrester – Type 1 + Type 2 for Use in PV Systems

DEHNcombo
• Prewired type 1 + type 2 combined lightning current and surge
arrester for use in photovoltaic generator circuits
• Approved fault-resistant Y circuit prevents damage to the
surge protective device in case of insulation faults in the
generator circuit
• Rated voltage is the same for all modes of protection and,
therefore, the arrester can also be used in earthed systems
Combined Arresters – Type 1 + Type 2 For protecting photovoltaic inverters against surges and even direct lightning • Tested to IEC 61643-31 / EN 61643-31 / EN 50539-11
• Space-saving enclosure with a width of only four modules
for up to 1500 V d.c.

• Applicable in PV systems in accordance with IEC 60364-7-712
• Operating state / fault indication by green / red indicator flag
