The disconnect blade assembly may have an open state and a closed state. A drive mechanism couples to the blade assembly to move the blade assembly to its various states. The drive mechanism couples to the interrupter trip assembly to provide for opening of the contacts of the vacuum interrupter prior to the blade assembly making or breaking contact.
