Abstract
A circuit breaker with a blocking mechanism having reversing levers which are rotatably mounted on both sides of the supporting lever of the circuit breaker, which reversing levers are in contact with the upper toggle in an interlocking manner. The reversing levers are moved when the switch latch moves. If there is an attempt to switch 'off' when the contacts are welded together, the further movement of the switch latch is prevented by stops on the selector shaft. When switching 'off' is performed when the contacts are satisfactorily open, the reversing levers automatically reverse the toggle system with regard to overcoming the throw-over point thereof, so that the 'off' position of the circuit breaker is reached reliably.
