The breaker trips because the speed controller draws too much current not because it gets hot. The breaker tripping is in no way related to the temperature of the speed controller. In any event if you can burn up a speed controller with no power to it inside the 5 seconds or less a breaker takes to reset there is a much larger problem on the robot.
