@SteveH posted:If you don't need 180 Watts of power for your sidings from the PH180, then limiting the max current to 5A would offer more protection for the trains on those tracks, combined with TVS. From another recent post, I saw that you already have TVS diodes connected to your ZWC outputs.
To my knowledge there have no been posts indicating which breaker is faster, but they are probably very close. The trip time for the Airpax "Instant" is 0.1 second in a overload condition.
Also of note: with one Z1000 you'd only need one breaker. The only reason I mentioned 2 was the pricing per unit for more than 2 is slightly less than buying 1 or 2.
Thank you so much, Steve, for the info here and in several other threads that I have read,
Yes, I do have TVS diodes on all ZW as well as the Z1000 outputs.
I am also adding a TVS diode at each track power drop.
I may put one in each of my DCS locomotives, but don't quite have that process in my mind just yet.
I will be ordering a pair of the above 5 amp breakers today.
To your point of mentioning 2 each, they also only sell a minimum of 2 units.
Thanks again,
Roger
