Assuming that the 2009 game and robot rules allow them, wouldn't the above breakers work just fine in the PD?

They've got ratings from 3 to 30A. These are the parts that the PD was designed to utilize in the "30A" position (refer to the following datasheet, chapter 3.2.2).

In a little bit of googling, I haven't found a distributor for Snap Action circuit breakers, other then AndyMark, who just started carrying the same sizes that came in the kit. I haven't called Snap Action, though.

As for the original question, the Snap Action breakers have much better trip characteristics then most fuses/circuit breakers for the application we are using them for. As for why the rules were written that way in the past, I don't know. Like Russ said, with a new control system, I think some of the electrical rules will be re-thought out.
