Der oberste Satz von Tabelle 15 gibt an, dass \u201eGer\u00e4te der \u00dcberspannungskategorie II unterliegen.\u201c Wenn die Nennspannung des Produkts AC220\u2013240 V betr\u00e4gt, entsprechend der letzten Wertezeile in der ersten Spalte von Tabelle 15, wird die Nennimpulsspannung auf 2500 V festgelegt.

\nIch muss sagen, dass die \u00dcberspannungskategorie (OVC) aus der Norm IEC 60664-1 stammt. Die folgende Tabelle gibt uns eine Definition.
