Modular single-pole surge arrester with a varistor and spark gap connected in series in the pluggable
protection module
• Multi-purpose surge arrester consisting
of a base part and plug-in protection
module
• Leakage-current-free series connection
of a varistor and a spark gap in the
pluggable protection module
• High reliability due to "Thermo Dynamic
Control" SPD monitoring device
