Hi all. Relatively new to the use of winches. Got the basic idea of installing, but have a couple questions if you all could help. I just recently purchased a Badlands 12000lb winch. I am aware of some thoughts about the Badlands winch, but for what I do it's about all I wanted to spend. Anyway, I mounted the winch onto a portable hitch mount with the intention of moving it from my F350 to my Jeep. The winch came with a circuit breaker(?) that is supposed to be mounted to the battery then wire out to winch. I mounted this on the truck. This breaker is kinda weird looking( to me anyway) as in it is 3 separate 50 amp breakers connected by 2 metal strips connecting them( pic below). One of the strips connects to battery, the other connects to wire going to winch. Here are my questions:
I want/ need to connect wiring in Jeep still. Can I buy a breaker like this somewhere? Or should I go with a fuse system instead? Is there an advantage to either one?

According to the manual, the winch at full load draws 300 amps. The circuit breaker that came with the winch looks to be 3 50 amp breakers. If my math is right that is only 150 amps. This confuses me.
If I were to go to the local auto parts store and buy something to put in the jeep, do I get either a fuse or a circuit that is 150 amps or 300?
Thanks for any help.
