You already have this, sort of. Each FET in each motor controller has a diode that will conduct in reverse when biased backward. However, the diodes will still allow approx. 1.2 volts in reverse bias plus wiring losses. That is sufficient to make electronics cross over to the light on the other side. (Stay away from the light, Fluffy)
If you can find the breaker you mention, send me the link, please. The 40 amp breaker we used prior to this one, did/does have a solenoid over current sense, to trip the breaker. It is also sensitive to vibration. So hit a bump with the breaker firmly affixed to robot frame and the main breaker would trip. Search for one of my breaker posts from 2000 on and I think I included an xray of the interior of that device.
