Recently purchased our pull behind camper to find out that all items needing to work off the 12 volt system wouldn’t work unless hooked up to the truck’s wiring harness or a 30amp electrical service even though we knew the camper’s battery was good.As long as you know your battery is good and there are no breakers tripped or broke fuses this is the next step.Some of these have a push button breaker. My old one did not & the new one seems to be a one & done type situation as well. So it’s nice that it came with 2 and it’s also nice to have the waterproof rubber protective casing since most installations seem to be exterior.Ease of installation for a DIYourselfer should only take minutes to remove & replace. TIP: Disconnect your battery first is always best remembering the simple phrase “negative first…negative last”.FYI: if you don’t own a voltage meter for checking your battery most auto parts stores will test it at no charge if you bring it in.

Worked well project up and running. No issues

Very good purchase

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.

Needed one for a auto battery charger that was kicking on and off and this fixed it. Old one was just getting weak.

Great product I would by again

They have plastic mounting points so take it as you will. But they installed like the older metal counterparts and appear to be functioning properly.

Review of 2 PCS DC 12V - 24V 30Amp Automatic Reset Circuit Breaker for Car, ATV, RV, Ship, Battery Chargers and More (with Cover)Key Features:Voltage and Current Rating:These automatic reset circuit breakers are designed for use with 12V to 24V DC systems and are rated for 30 amps, making them ideal for a variety of vehicles and equipment such as cars, ATVs, RVs, ships, and battery chargers.Automatic Reset Function:The circuit breakers feature an automatic reset function, meaning that after a short circuit or overload, the breaker will automatically reset once the fault condition is cleared. This provides convenience and reduces the need for manual intervention, ensuring continuous operation without the hassle of manually resetting the breaker each time.Wide Application:These circuit breakers are versatile and can be used in automotive, marine, RV, and battery charger systems, among others. They're designed to protect electrical circuits from overcurrent, ensuring the safety of sensitive electrical components.Durability and Build:Constructed with high-quality materials, these circuit breakers come with a protective cover, offering enhanced durability and protection from dust, moisture, and debris, which is essential for outdoor and automotive environments.Compact and Easy Installation:These circuit breakers are compact and designed for easy installation in most standard applications. Their design allows for direct mounting onto the electrical circuit without requiring complex tools or modifications.Pros:Automatic Reset Function: The automatic reset feature is particularly convenient, saving time and effort for users who don't want to manually reset the breaker after a short circuit or overload. This is especially useful in automotive, marine, and RV applications where frequent interruptions can be inconvenient.Wide Voltage Range: With compatibility for both 12V and 24V DC systems, these breakers can be used across a variety of vehicles, machinery, and electrical setups.Protective Cover: The included protective cover shields the breaker from external damage and elements like dust, moisture, and dirt, making it suitable for outdoor and high-use environments.Versatile Applications: Suitable for multiple applications including cars, ATVs, RVs, marine vehicles, and battery chargers, providing protection across a wide range of electrical systems.Compact Size: The small and compact design makes for easy installation in confined spaces and does not take up much room in the electrical setup.Cons:Limited Amp Rating: The 30-amp rating may not be sufficient for systems that require higher current protection, such as larger RVs or high-powered machinery. Users needing protection for higher-current systems will need a higher-rated circuit breaker.Potential for Resetting Too Frequently: While the automatic reset function is convenient, in some cases, it may reset the breaker too frequently in situations of consistent overload, potentially leading to a failure in protecting the system adequately. This could be problematic if the cause of the overload is not addressed.Not Ideal for AC Systems: These breakers are designed for DC systems only. They are not suitable for use in AC circuits, so users must ensure they are using them in the correct system.Best For:Automotive Applications: Perfect for cars and ATVs, where electrical systems can experience overcurrent conditions that need protection without manual intervention.Marine Systems: Ideal for use on boats or ships, where electrical equipment is vulnerable to overcurrent conditions due to harsh environments.RVs: Suitable for RV systems, offering protection to batteries and other critical electrical components, making sure the electrical system stays safe during operation.Battery Chargers: These circuit breakers are particularly useful for battery chargers, preventing damage to charging systems from overcurrent or short circuit events.Final Thoughts:The 2 PCS DC 12V - 24V 30Amp Automatic Reset Circuit Breaker offers a reliable and convenient solution for protecting electrical circuits in a wide range of vehicles and systems. Its automatic reset function is especially useful for automotive, marine, and RV applications where manual intervention may not always be feasible or desired.While it’s perfect for smaller electrical systems that require up to 30 amps of protection, users with higher current needs or those who are dealing with AC circuits will need to look for a more powerful or different type of breaker. The included protective cover and easy installation further enhance the overall value, making these circuit breakers an excellent choice for anyone looking for affordable, effective, and easy-to-use protection for their DC electrical systems.
