摘要： Handle assemblies for circuit breakers are disclosed. One illustrative handle assembly includes a housing defining a first aperture, a seal extending around a perimeter of the first aperture, a handle extending outwardly through the first aperture and pivotable about a pivot axis located within the housing, a shroud coupled to the handle to move therewith and located at least partially within the housing, and a biasing member connected to the handle and to the shroud. The shroud includes an outer surface that faces the seal, and the biasing member biases the outer surface into continuous engagement with the seal throughout an entire pivotable range of the handle.
