Generic100 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 used this during my installation of my inverter instead of a fuse connect, worked out great.

No matter what I did my multiple capacitors and amp on my car stereo had a parasitic draw. Which left me with a dead battery more than once. I ordered 2 of the 200 amp, continues duty relays and put one of the DC breakers in front of each.Being a retired union electrician I'm a little upset with myself for not thinking of a DC breaker instead of fuses, myself.

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 product in an area that was exposed to moisture, but shielded from rain. After about a month, the spring action on the disconnect was getting corroded/stuck and made the fuse breaker unreliable. It's likely possible to take it apart and add some grease, but I haven't done it yet.

Used this inline fuse for a solar array and it worked great! Especially loved the removable ferrule for larger gauge wire - made adding the fuse a breeze

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 bought both styles of circuit breaker from this vendor. The inline style and the waterproof style. Both breakers were rated for 150A. I used the inline style on a small 15KW solar system/battery bank. It was a redundant fuse in place for the Growatt 3KW inverter. The breaker tripped a few times during a 1 month period of time when running loads that were around 2000W or 80-85A current. After that, the breaker became unreliable and started to randomly shut off power with anything about 40A continuous draw. It did not trip the breaker though. It just cut power intermittently so that the inverter would shut off and restart. This happened for a while. I thought it was a faulty inverter but upon tearing down the system, I found that the breaker was the culprit. Also when it cut power, it wouldn't trip the breaker. The breaker is stuck in the closed position so now it wouldn't be able to be tripped and would always supply power. Dangerous situation.Now I also bought the waterproof version of this breaker to fit onto my fully electric boat build to be a redundant breaker for the outboard which draws 125A max current. I have a shunt monitoring the output of the motor and it never exceeded 125A. However, the breaker tripped which caused it to cut power abruptly while in the middle of the water. Now that's fine, I went and reset the breaker, but everytime there after, it became unreliable like the in-line breaker and would cut power randomly when drawing anything above 40A of continuous current.Anyway, moral of this story, this is an unreliable product that is dangerous in some situations. Do not buy this if you need to draw more than 40A and maybe size up your breaker if you have no other option. Regardless, I would not recommend it and I will search for a better product in the future.

Easy to install . Adds low cost protection and s off switch
