If anyone has done any side by side comparisons between the PSX-AC and the Airpax Instant breakers, I'd really like to know more about your observations.
I have not done any comparisons, but the Airpax is reacting in 100 milliseconds. The PSC is microprocessor controlled, it can react in microseconds. Not even close. That's not to say 100 milliseconds isn't fast enough for us.
