Abstract
A gas blast circuit breaker comprises one breaking assembly having a supporter and two breaking units at least movable contacts of which are supported on opposite ends of the supporter, and the other breaking assembly having a supporter and a single breaking unit at least a movable contact of which is supported on one end of the supporter. The two breaking assemblies are so arranged as to have only one breaking unit between the two supporters, whereby flows of blasting gas in the three breaking units of the two breaking assemblies can be prevented from interferring with each other.
