Power circuit breaker

A power circuit breaker for switching electrical voltages having a first electrode which can be connected to a first pole (A) of the high voltage to be switched, and a second electrode, which can be connected to a second pole (B) of the voltage to be switched, with switching means being provided, which are suitable to move at least one of the electrodes along a switching path depending on a switching state and thereby to move the electrodes toward each other or away from each other, wherein at least one secondary electrode is present, which is situated in a vicinity of the switching path, and wherein the at least one secondary electrode has a contour such that it is thinner in a region of the switching path than on a side facing away from the switching path.
