Technical data
• Pluggable arrester (impedance-neutral plugging/unplugging without
interruption)
• Can be tested with the V-TEST testing device
• Optional monitoring function with status display and alert functions
for MOV components
• Version with floating-earth PE connection for avoiding voltage
potential differences
• Tested in accordance with IEC 61643-21
• Integrated PE foot, safely discharges up to 20kA (8/20 μs) and
2.5kA (10/350 μs) to PE
