I've checked on this and the Jaguar does not require a neutral signal following a fault (anymore). The original prototype firmware of Jaguar did, but it was fixed a long time ago. The documentation is incorrect and will be changed shortly.

Not surprising. A presentation at the 2008 FIRST Robotics Conference by Al Skierkiewicz says the breakers can function for a few seconds with up to 600% over current and almost 10 seconds up to 200% over current. See

In testing at Luminary Micro, we drove a 150 lb robot rather mercilessly and didn't experience an over current fault. The only time an over current fault was generated was when the wheel of the robot was locked.
