Direct replacement. I think my previous fuses were 30a. So I did 40a for a little more headroom. If you don't know much about electricity, replace yours with the same rating.I appreciated the weather covers, but the tabs you have to manually push out and cut, it's tedious, minus one star.GREATLY APPRECIATE the hardware included; some other brands don't provide the screws to mount this with. Happy to say this product included those screws. Also includes fresh washers for the posts.Price was a little on the high side, but I am willing to pay a little extra for the piece of mind.Finally, these are AUTOMATIC breakers. They do not have the "reset button". Take that into consideration when working with; if they get too hot, they will flip, and then once they cool down they will turn back on.Build quality is good made out of metal, and the functionality is as-expected. Fit was perfect.

These are good little circuit breakers. I got the 30 amp version to protect a portable lithium 12 volt setup with a 30 amp Anderson outlet socket. I didn't want to risk a shorted cable burning up that system so I used these CB to protect the outlets. I tested these with a dead short and they cut out very fast. It took almost a minute to reset but they worked fine.

I use Anderson Connectors to connect inverters to my backup batteries. My larger 100Ah lithium deep cycle battery has 3 different size Anderson connectors, 50A/120A/300A, for various uses. The main use of that battery is for 3K watt inverter on the 300A connector, and I also use the 50A connector for the 20A charger. I also have a 50A and 120A on a car battery for various smaller inverters, 500W to 2KW, depending on my portable power needs. These connectors give my inverters, chargers, and other devices universal connections for various uses.

These breakers can be used in a lot of applications- RVs, marine, cars, solar, or any other little bench project. They all have studs to connect the cable to, and they have to be connected properly to work properly. They also have covers that fit snugly over the entire connector, although getting the top cover on is fussy and takes a bit of time. I'm glad I don't have to do it very often.Info about these- in case you don't know... there have an auto-reset feature. They work on temperature, so when the current going through the internal connector reaches a certain temperature, it clicks off. After a short time, 10-30 seconds usually, it clicks back "on" because the internal connector cools off a bit and goes back to the closed position. Kinda cool how that works. If the short or overload is still there will will continue to click on/off until the problem is fixed. When this clicks off depends, of course, on the amperage rating. There instructions say how it should be hooked up.After this is mounted and the wires connected there's a plastic cover that swings over the top. It covers the studs as well as the switch. When done it's totally covered, so it looks nice and clean, and protected from splashing water and dust/mud. Putting the cover over the studs takes some fidgeting around, but after about 10 seconds or so it manages to go on.These are nice because they work as a regular breaker, but I don't have to go to the breaker to switch it back on. When something happens I'll know because the light (of whatever) is off. I'll check the problem, fix it, wait for this to reset, and all is good again.The downsides:- this type of breaker requires that I have to wait for it to reset. When I'm standing there waiting for 10-30 seconds (or whatever the time is) it feels like a long time. It's the price I pay I guess.- this works on temperature and not excess current. If this is in a warm/hot place it may click off before it should because it senses a lot of heat. Conversely- if it's in a real cold place it might click off too late, possible damaging things. This is something to consider in your situation, and think about what you want to protect.- these have a current rating, but looking at the specs for some of these is wise. For example- some specs on breakers like this I've seen that a 20A rating means it will click off at 50% over rating (20A) in 8 seconds, and at 100% in 2 seconds. That could be a long time to wait for a breaker to click off while it fries your circuit. Again - think about your application.In the end- for small applications and having the auto- reset feature, these are a good buy. I use them fairly often with no issues.

I am currently only using one of the 4 in my application. These are very similar in quality and feel to one of the name brands I use. I did a quick short test and it did work like a champ so I am reasonably confident these will work just fine.

Used this to replace the main DC CB on my RV. Nearly a drop in replacement. The screws holding the original CB in were larger, so I had to JB Weld the holes and re-drill. The cover is a nice touch, as my original didn’t have a cover.

These Red Wolf breakers are nearly identical to the name brand units. I shorted one as a test. It tripped immediately and reset a couple seconds later. Unfortunately, I didn’t have an easy way to test over current type faults but the breakers seem pretty trustworthy. It’s a good sign when a product comes with instructions that list performance specs.I like this style breaker since it can be used as a small junction/power post. Oh… and here’s a tip to clear up any confusion: the shorter copper stud is the power in (it’s marked bat). On these I think it might be important.5 stars for matching name brand quality at less than half the price.
