A drive train is for a displaceable contact on a breaker contact arrangement in an electrical power breaker. A coupling element displaceable against a stop and arranged between the moveable contact and corresponding drive element is provided with an anti-bounce device, including a catch element and a counter piece. The catch element which may be swung into a catch position as a result of the inertia exerted on the centre of gravity thereof, when the coupling element strikes the stop, includes a working surface extending in the pivoting direction to forma momentary working connection with the counter piece. A retaining spring is additionally provided on the catch element to guarantee that a rebounding of the coupling element into the position corresponding to the close state of the breaker contact arrangement does not occur.
