Isolating Spark Gaps

Isolating Spark Gaps
Isolating Spark Gaps • For indirect connection / earthing of functionally isolated parts

of installations under lightning conditions
• For lightning equipotential bonding according to IEC 62305
• With corrosion-resistant stainless steel connections
• For installation in buildings, outdoor locations and damp
rooms as well as for underground installation
• Extremely heavy-duty devices

For lightning equipotential bonding according to IEC 62305 as well as for use in IT
installations according to IEC 60364-5-54.
