Claim:
1. A triggered arc flash arrester comprising: an envelope formed with an interior having a reduced pressure therein; a plurality of conductors that are stationary and that are partially disposed within the interior and separated from one another along a longitudinal direction by at least a first gap situated between the plurality of conductors within the interior, the plurality of conductors being structured to support an arc across the at least first gap that is electrically in parallel with an arc fault and that facilitates extinguishing of the arc fault; and a shield apparatus disposed within the interior, the shield apparatus being situated generally between the at least first gap and the envelope and being structured to protect the envelope from damage due to the arc across the at least first gap, a region of the shield apparatus being of one thickness in an alternative direction between the at least first gap and the envelope, the region being adjacent the at least first gap and extending at least along the entirety of the at least first gap along the longitudinal direction, another region of the shield apparatus being of another thickness in another direction between a conductor of the plurality of conductors and the envelope, the another thickness being less than the one thickness, the another region being situated adjacent the region.
