ABSTRACT:
A vacuum load break switch uses a vacuum interrupter for the load break device together with a series connected visible disconnect which is interlocked with the vacuum interrupter mechanism. Further, the visible disconnect is grounded in the fully opened switch position. A manual switch operator is provided together with interconnect means interconnecting the manual switch operator to both the visible disconnect switch means and the vacuum interrupter in a manner such that in a switch closing operation of the manual switch operator the visible disconnect switch means closes before the vacuum interrupter means and in an opening operation the vacuum interrupter means opens before the visible disconnect switch means. Additionally, an additional solenoid operated switch operator is coupled to the interconnect means for opening the vacuum interrupter through solenoid action.
