Help with Main 12V Breaker spec

I am looking for the sourcing for a main 12V breaker at the positive buss for a 2000s era Classic 30. These are not the breakers at the 12V distribution box.

I decided to clean up some wiring, fix some poor crimps and replace some of the horribly stiff wiring with stranded marine cable. AS tightened one of the nuts on a breaker post so tight that it broke the plastic base of the breaker when loosening. It obviously works no more. I can't see the specs or brand without taking the whole buss off, and I'd rather not do that without new part in hand.
I think they are 30 amp self resetting, but I am not sure. The branch breakers in the distribution box are manual resetting.

Does anyone have that brand, part number and spec?

Thanks much!

Oh! I also found one installed upside down! Copper post goes to the copper buss bar right? The other 4 are installed the way. They aren't bi-directional are they?

I am doing the same thing you are, but I am replacing all of the short stop fuses with ATO fuses and a SafetyHub 150. I have not yet replaced the fuse you are talking about, but my drawing (2004 Classic) show that it is 50 amps.

I will be replacing mine later this coming week. I'll let you know if it is different.

Thanks Dave,

I tore into it last night. Standard ShortStop 12V N10 30A self resetting breaker (sans bracket). Amazon will bring it today.

1st pic is the backside of the buss showing the brand and specs.
2nd pic is the buss front before removal.
3rd shows the wall mounted battery cable protection breakers. I think they are 50A.

The buss breakers are 30s. Click image for larger version

Yes, I have done a few mods over the years. Shunt for monitor, solar install, desulfater, victron battery protect, relocation of components, etc. Its getting crowded in there. No room for Mr. Reactor.
This exercise started with eliminating the battery doors and bringing 2 lifeline gpl 31XT AGMs inside. Click image for larger version

Just a couple more pics that might be worth posting for posterity and visual documentation.

Yours looked like mine did three years ago. I liked my set-up, but the Lifeline AGMs take too long to charge. With the steeply discounted lithium prices in November, I decided it was time for more capacity and quicker charging.

Below is a picture from last week before I started tearing out the rats nest and rearranging. BTW, the SafetyHub 150 is really a nice product to replace the Airstream distribution panel! I'll send a final picture when it is done.

I wouldn't call that a rat's nest. Sure its not breadboard neat, but that takes away storage space. You have room behind the electrical center for a breadboard. I'd lose my subwoofer it I didn't put a battery back there.

I am losing the box around the Magnum inverter which will help. I am going to put the SafetyHub in front and to the left of the magnum so it will be easy to access. I am putting in 4 lithium batteries where the current batteries are, so that will take up the same space. I also put in a 20A DC to DC charger, and that is already mounted on the left side couch trim piece. My solar charger is mounted inside the right side couch arm rest. I am trying to neatly bundle all the wires. We'll see how it turns out.

BTW, I lost my battery boxes just like you did (on my original AGM install). Stupid design in the first place. Gave me a lot more room

If the 50 amp AC breaker is hooked up to your outside pedestal connection, then it is serving as a main breaker and adds safety to your 50 amp power cable. That is why it is wired backwards. The same goes for the 12 volt DC input from the batteries. I believe the lugs on the AC breakers are Torx 20 that makes them a lot easier to tighten correctly.

These are all 12 volt breakers that I am talking about.
There are 2 (1 on each battery cable) 50 amp breakers. The 2 positive cables attach to the buss bar. The bar has 4 "main breakers". One breaker feeds the distribution panel which has 7 breakers to serve the house. The next buss breaker was originally empty. The next served the jack, charge line from the tow vehicle. The last one serves the hydraulic brake actuator.
It was the one for the charge line and and jack that was upside down.
