Abstract (en)

The circuit breaker includes an auxiliary drive mechanism (3). This mechanism is constructed to reverse the direction of movement of the second arc contact section (2). Reversal takes place during circuit breaking, and occurs when the constricted section (6) is no longer partially blocked by the contact end section (2). The auxiliary drive is an electrodynamic drive. It is alternatively taken from the main drive. The auxiliary drive mechanism includes at least one cam track plate (14). Equations describing the constriction geometry are provided. An independent claim is included for the corresponding method.
