SPD Type 1+2 Surge arrester range with high
performance “Low U
p
”- Single phase/three
phase system
• Surge arrester suitable for 230/400V system
applications to prevent overvoltage effects
caused by direct or indirect lightning strikes
• To be installed at the boundary of LPZ0 and
LPZ1 zones
• Low U
p
to protect senstive equipment
• Visual indication of varistor status -
Healthy/Replace
• Contact for remote signalling of varistor status.
