Reply to "circut breakers"

As I recall, there are two paths for over-current protection to kick in with the PH180 breaker.  I believe Dale Manquen did an analysis of the operation some time back.  One was a slow path that would allow a modest overload, the other was a quick reaction to a direct short.  I know that when I have a direct short, the PH180's trip on the spot, well under a second.  You'll see two paths to energize the relay, one has a much larger resistor and capacitor, the other at a higher output level of the 100:1 sensor has a much faster reaction time.
