This blocking member allows the hook to move smoothly without being hindered by the connection. [Effects of the Invention] According to the present invention, the connection line does not obstruct the movement of the hook.
Since stopping in the middle of the operation process can be prevented, the operation of the movable contact block becomes smooth. It is possible to prevent contact welding and failure to shut off due to oxidation, and also has a structure that detects the operation of the tripping member and trips the other pole in a multi-pole circuit breaker constructed by connecting multiple single-pole circuit breakers. In this case, since the common tripping mechanism operates reliably, it is possible to prevent the other pole from being unable to trip.
