7P SERIES
Surge Protection Device (SPD)
7P
SERIES
SPD Type 1+2 and Type 2 Surge arrester range
for Photovoltaic applications
• Surge arrester for protection of DC side (1020V)
of systems in photovoltaic applications
• Protects equipment against overvoltage
caused by direct lightning strike (Type 1+2
only) and induced overvoltages (Type 1+2 and
Type 2)
