I originally got a dud but Amazon quickly replaced it with a working breaker which is now part of my off grid solar battery project. I have a few safety disconnects in various parts of the system and this is acting as one of those safety points, haven't had any issues - I'm content with this breaker for its intended purpose.

I recently purchased the Pjerjzn DC Miniature Circuit Breaker 50A 2P 1000V Solar Circuit Breaker DIN Rail Mount, DC Breakers for my solar panel installation, and I'm quite impressed with its performance. This circuit breaker is designed for DC applications and is specifically tailored for solar installations. The DIN rail mount design made installation a breeze, and the build quality feels very robust.One of the standout features of this circuit breaker is its high voltage rating of 1000V, which is essential for solar applications where high voltages are commonly encountered. The 50A current rating is also suitable for medium-sized solar setups, providing ample protection against overcurrent situations.I found the compact size of the breaker to be convenient, especially when working in tight spaces within the electrical enclosure. The clear labeling and indicators also made it easy to understand its status at a glance.Overall, I'm satisfied with the performance and build quality of the Pjerjzn DC Miniature Circuit Breaker. It offers reliable overcurrent protection for solar installations and is a worthwhile choice for anyone looking for a durable and high-performing DC circuit breaker.

I am using this circuit breaker on my solar system I use to power things in my shed, such as a deep freezer and various power tools. It has been working flawlessly and perfect for my needs. As you can see in the photo, I have this breaker installed between the incoming PV wires from the solar panel and the wires feeding into my solar charge controller. My charge controller can only handle up to 40 amps, so installing this 40 amp breaker will protect my system in the event something goes wrong and too much current is coming in.The breaker is also very helpful for when I need to clean or reconfigure my solar panels, as I can safely stop incoming power from reaching the charge controller. I have been using it for over a month without any issues, and plan on getting another one just like it to go in between the power inverter and my batteries soon. It looks and feels like good quality, and based on my expletive I would recommend it to others.

I'm not currently using this breaker as a breaker, just a quick-disconnect between some solar panels and a charge controller. For that purpose it's working exactly as you would expect. I don't have any reason to think that the 60A breaker functionality wouldn't work, I just don't have a use for that and I don't have a way to test it.It feels solid enough (despite the rattly terminal screws, which are always like that in this type of product). I appreciate that it came with a (tiny) DIN rail for mounting. It's actually annoying that some similar products don't come with that. So kudos to the manufacturer for including it.One thing I didn't like is that it has a CE symbol on it, but it's sold in the US market where UL is really what's needed for safety certification on electrical devices.4/5 stars. It's working great for me and my DIY projects, but it may not meet code in the US -- do your homework on that part.

I just installed this into a small solar system as a disconnect between the solar panel and the charge controller. works good, and easy to install.

Nice Breaker - tested and breaks on short. Fits nicely on the din rail - snug but still slides. Mine is sandwiched in between a friend and an end stop. I'm using this 60 amp breaker for a 10 amp RV fridge right now - she's soon to be swapped out. She's slated to be use for a 1500w DC water heating element I'll be installing in a beer keg - because, some folks like warm beer.5 Stars for The Pjerjzn 60A DC MCB

I got this as a solar panel cutoff for our travel trailer. It is inside the trailer, so I didn't need a weatherproof breaker. It installed easily with the DIN rail and 6AWG wire fits in the contacts. I can't attest to its functionality as a breaker, but it switches easily and overall seems like good quality for the price.
