The response times for circuit breakers are typically much longer than for equivalent-value fuses. If you go this route (and if it's determined to be FRC2011-legal), make sure to check that the response time of the device is within whatever time you decide is acceptable. Based on what I'm reading, it sounds like it would need to trip within 1 sec @ 7A (assuming one per motor) to prevent the "smoking" issue.
In most cases on FIRST robots, we have more material than in we need in some places and less than we need in others. That single phenomenon is the leading cause of robot failures. - Paul Copioli [more]
