Just what is the difference between a circuit breaker rated for DC and one rated for AC?
I had always thought that DC had a greater ability to weld the contacts together or pit them, but I never had confirmation on that.
Is the DC resistance of the thermal element different? Low voltage systems (which are usually the DC ones, but that's hardly a rule) are affected more seriously than higher voltage systems (such as 125VAC). Any truth to that theory?
