Abstract: Discloses a gas-blast circuit breaker comprising two spacedapart stationary contacts and a movable bridging contact extending therebetween. The bridging contact has an arc-running surface facing the space between the stationary contacts and a centrally located gap that divides the arc-running surface into two spaced-apart sections. Two slots in the bridging contact extend in opposite directions from the gap generally parallel to and behind the arc-running surface. This configuration of the bridging contact is such that the current paths through the two arcs formed upon contact separation are of such configuration that magnetic forces are developed for driving the arcs together and accelerating their merger into a single arc.
