Abstract

A circuit breaker (1) is proposed, comprising a live line (2) between a live supply connecting terminal (3) and a live load connecting terminal (4), a neutral line (5) between a neutral supply connecting terminal (6) and a neutral load connecting terminal (7), and a mechanical switch (8) being located in the live line (2), which mechanical switch (8) is controlled by a processing unit (9) of the circuit breaker (1), comprising further a trigger (10) for interrupting at the live line (2) and/or the neutral line (5), wherein an auxiliary line (11) is connecting the neutral line (5) with the live line (2) between the mechanical switch (8) and the live load connecting terminal (4), with the auxiliary line (11) comprising serially a current limiting resistor (12) and a control switch (13) being controlled by the processing unit (9), with the processing unit (9) being adapted to control the control switch (13) and to open and close at least the mechanical switch (8) for a removal of oxidation layers of mechanical contacts of at least the mechanical switch (8) by controlled arcing.
