Abstract
An assembly and a method for damping contact bounce in high-voltage circuit breakers include a vacuum interrupter and a holder for the vacuum interrupter. The vacuum interrupter includes a housing, at least one movable contact piece and at least one fixed contact piece. At least one mass body is mechanically connected to the at least one fixed contact piece in order to effect damping of the contact bounce between the at least one fixed contact piece and the at least one movable contact piece during a switch-on operation of the high-voltage circuit breaker.
