Abstract
A concept of a double-breaking contact system with a rotating contact arm is disclosed. In at least one embodiment, a novel arrangement of fixed conductors that cross over the contact arm is presented. A double-breaking contact system for a low voltage circuit breaker of at least one embodiment includes a double-breaking contact arm extending along a longitudinal axis and being rotatable across a central bearing; a first fixed conductor and a second fixed conductor, each conductor contacting one end of the contact arm, respectively and having first segments below the contact arm, second segments above the contact arm and third segments crossing over the contact arm and connecting the first segments with the corresponding second segments of each conductor; wherein the first segments and/or the second segments are arranged parallel to each other for guiding a current in a parallel direction through the respective first and/or second segments, but reverse to the current in the contact arm.
