Abstract
A high voltage contact control system includes main contacts on positive and negative feeder lines and a short circuit protection system configured between the positive feeder line and the negative feeder line. The short circuit protection system is configured to be operably connected between the positive and negative feeder lines and configured to selectively provide a bypass path between the positive feeder line and the negative feeder line to divert current away from the first and second contacts. The short circuit protection system includes first and second state arc prevention elements that can operate in at least two modes. The bypass path is established by having one of the arc prevention elements in a fully on mode and another either fully on or in a linear mode.
