Generic 150 Amp Waterproof Circuit Breaker,with Manual Reset,12V-48V DC,30A-300A,for Car Marine Trolling Motors Boat ATV Manual Power Protect Audio System Current Overload Protection

I have this inline with a larger Advanced Gel Media (AGM) battery that supplies peak current and backup for my electric gate opener. Its fed by a 13.8 v 50 amp switcher that most of the time is just idling but puts out current when the gate driver starts. The risk here is that the AGM can put out hundreds of amps of current in the case of a short and destroy the entire opener and possibly cause a fire (safely contained, but still bad news). So this goes in line with the battery and also acts as a disconnect for servicing the system. The connection system is really well thought out for heavy gauge wire (8 gauge in my case) to hook up and provide large surface area contact for high current. The breaker trips when it should (using a 0.1 ohm load to generate 120 amps of current without arcing. Easily reset. I have a couple of other applications for 12v high current that I will use these for. As always, bought it retail, no free goods, no compensation for writing a review. If I like it, I say so and why, if I don't like it you know about that also.

I use this online breaker for car audio amplifier power cable applications. The quality is nice. The materials used can handle some abuse without cracking. As well, the breaker mechanism is smooth and opens at the rates loading. The construction is sealed up nicely, too.I highly recommend this as a better alternative to a conventional in-line fuse holder. Just be sure it will fit in the location you wish to install it.

Got this to use as a fuse/circuit breaker on a solar powered portable audio system I carry around on my Kayak. It was easy to install and it seems to be of good quality. They don't seem to be cheap plastic, and so far seem to be able to handle all weather. I like having the ability to check for a short and then reset the breaker if I need to, it has saved on the cost of fuses. When the circuit opens it provides a solid click and holds for about a minute before allowing closure. Worked every time . I like the quality and how easy these are to install and use. Sure beats a one time fuse and you can disconnect it when you're working on the system. I have these installed on everything.

I installed this between my battery and my sound equipment in my car, I’m running a lot of load but probably a little over kill with this thing. Still I blew one fuse on my previous set up and didn’t want to be running to the store the next time, so I got this. Hasn’t tripped once except under load test and it did everything it should.

This was used to install a power circuit for an RV and the breaker seems to be a better option than having extra fuses. No idea how water resistant it will be but it is protected undue the hood.

Me agrada que es muy rápido. Actualmente lo he conectado como protector en un circuito de 110 Amp. debe desconectar a los 80 Amp. Lo dejaré a prueba y luego actualizaré la calificación.

I had to drill out the ends (a good amount) just to fit 0 gauge wire. Also couldn’t use the plastic end caps so I used marine grade heat shrink.

The lugs are so small that no one could possibly get this to support anything beyond 50 amps at 12v. None of my properly sized wire fit, which is a major design flaw for a fuse that's supposed to support up to 300amps.
