Surge protection for U_k0/S₀ interfaces (telecomm.)

The following signals are protected by the U_K0 :

• Two-wire input interface (telephone cabling) – U_K0
• Pluggable arrester, with no-interrupt and impedance-neutral plug-in and pull-out
• Low residual voltage
• Can be tested with the V-TEST testing device
• Integrated PE foot, safely discharges up to 20 kA (8/20 μs) and 2.5 kA (10/350 μs) to PE
