Patent attributes
An improved modular vacuum interruption apparatus includes a vacuum interrupter, a first connection module, and a second connection module, with the first and second connection modules each being connectable and disconnectable with a pair of electrodes of the vacuum interrupter. The first connection module is selected from among a plurality of connection modules that are similar yet different and can be used interchangeably to form various permutations of the improved modular vacuum interruption apparatus. The second connection module is likewise selected from among a plurality of connection modules that are similar yet different and that are interchangeably usable with the vacuum interrupter to form different permutations of the modular vacuum interruption apparatus. Similarly, the vacuum interrupter is among a plurality of vacuum interrupters having different specifications but that are usable interchangeably with all of the first and second connection modules to form different permutations of the modular vacuum interruption apparatus.
