Sorry if I am repeating myself here but I want to be exact so I can place an order and dont have to reorder later.
120v, 10A max draw I can get the Dual Pole 10A D-curve breaker and connect both the Hot and Neutral wires to it. This is the one you recommended.http://www.factorymation.com/s.nl/it.A/id.5698/.f?sc=2&category=15748
24v AC 2A max draw from the 2x gas valves, I need a 2A breaker for just the hot side. Like this one.http://www.factorymation.com/s.nl/it.A/id.5681/.f?sc=2&category=15748
And for the DC 3A PSU I need a 3A B curve breaker like this one.http://www.factorymation.com/s.nl/it.A/id.5669/.f?sc=2&category=15747
I know I could use a fuse, but if I am already putting in a DIN rail with 3x breakers, might as well make it 4....They have a nice 10cm DIN rail for $1 that looks like it will work nicely.http://www.factorymation.com/s.nl/it.A/id.60442/.f?sc=2&category=21332
All of the valves and electronics are on 12v so I want it fast acting. Just 2 gas valves are on the 24v line.
I posted the link to the 2-pole breaker because it was the equivalent (but less-expensive) product to the one you had listed. You really only need a single pole breaker for the 120v line. Aside from that, it looks pretty good to me.
