ABSTRACT:
Vacuum interrupters having improved structural rigidity and internal vacuum integrity are provided for use in vacuum circuit breakers. Due to the design and construction of the endcap assemblies, the vacuum interrupters require a reduced total length of brazed seams, and the incidence of vacuum loss due to faulty seams is thereby reduced. An improved stationary terminal assembly including a reinforcing member providing increased structural rigidity is also provided.
