12 Volt Circuit Breaker Accessory Kit

I'm installing the battery relocation accessory kit in my M923 (relocates batts from under the pass seat to the toolbox location).

For several M900 variants, it calls for a "12-VOLT CIRCUIT BREAKER ACCESSORY KIT" Part No. 57K3611 and it is not included in the relocation kit. It goes on the 12 volt leg of the heater circuit. I need one. I've done all my searching (here and google, etc.) and cannot find one. Can someone point me to a source OR AT LEAST a part number for the 12 volt circuit breaker? I didn't know the normal MV waterproof circuit breakers came in a 12 volt configuration. I can make up the wiring from the pictures in the instructions. I just need the circuit breaker. I have found reference to the breaker kit (NSN 2290-01-475-9450, again 57K3611), but no parts breakdown so I can find a number for the breaker. Any help is appreciated.

I did check out the P to P program and its interesting that the 24V side of the heater is breaker-ed but the 12v side is not. However, based on the rewiring I need to do for relocating the batts (in the kit) i **guess** I can see why they want the 12v side breaker-ed. The wiring lengths get much longer and wiggle all over h&ll now so I suppose they want to stop a fire.

Thanks for any help,
Allen

Searching for Breaker info posts on the 12v breaker for batt. relocation, and I also saw the lack of replies.
I am in the same situation, I just figured I would leave the 12v leg disconnected and taped off, until I could solve the problem. That's should be OK don't you think? Just a one speed heater motor.
Did anyone ever find a source of the 57K3611 Kit as I would prefer to keep the work to spec. ?
Actually all I really need to know is what is the Amperage of the breaker,I was figuring 15-20 amp would work. I would appreciate any thoughts from you or members who have done this modification.
Thanks Frank

The Klixon link is for the 28.8 ones. I couldn't find any Klixon 12V ones so I ended up installing a standard military 15 amp one. I usually run my heater motor on low and it has not tripped yet. I wanted to test it and see what it would take to trip one on 12V but never got around to it. No fires the last two winters and I used the heater on low. Proof in the pudding?
