Abstract
A hybrid switch assembly for a circuit breaker assembly is provided. The circuit breaker assembly includes a housing assembly and an operating mechanism. The housing assembly defines a power electronic switch assembly cavity. A hybrid switch assembly includes a number of conductor assemblies, each conductor assembly including a movable conductor, and a stationary conductor. Further, each movable conductor is structured to move between an open, first position, wherein each movable conductor is spaced from and not in electrical communication with an associated stationary conductor, and a closed, second position, wherein each movable conductor is coupled to and in electrical communication with an associated stationary conductor. A number of the conductor assemblies further include a power electronic switch assembly. Each power electronic switch assembly includes an isolation contact assembly. Each isolation contact assembly is selectively coupled to, and in electronic communication with, the stationary conductor and the movable conductor.
