<p>The breaker has a dielectric-gas interrupting chamber (1) with contacts that are disposed longitudinally to an axis. The chamber (1) is connected in series with a vacuum bottle (2) containing a fixed contact (2A) and a moving contact (2B). An actuating unit has an arrangement for re-closing the moving contact such that a single control (4) performs re-closure before the moving contact reaches its open position.</p> |
