Well, the PSX-AC is solid state switching, so in theory it could interrupt power in microseconds. The PH180 has electronic sensing, but a relay is actually used to interrupt the power, so it's reaction time is probably a few milliseconds.

I don't really know if the difference is all that significant as far as failure rates of locomotives is concerned. I personally consider the protection of the PH180 circuit breakers sufficient for my use.
