    Abstract: The invention relates to a method and an arrangement for determining an end-of-life of an overvoltage protection element (2) by determining (101) a predefined voltage limit based on a nominal voltage, determining (102) a measuring voltage across switch components (5) of the switch arrangement in connection with a switch-off event, and determining (103) that the overvoltage protection element (2) has reached its end-of-life when the measuring voltage is equal to or lower than the predefined voltage limit.
