    • Very good circuit breaker
Model: CB-03-30A
I have purchased these circuit breakers in the past. I bought 30 amp and 20 amp breakers from this company. These are quality, high durability product. I use them for my 12 volt solar battery generator project. Very simple to use with a two wire install. I have had no issues with these circuit breakers and I will purchase more in the future. It is a good buy, especially when you purchase more than one. They function well and they are small in size so they are easy to fit in a solar toolbox project. I have had no issues with any electrical problems such as Sparks, it appears to be a safe product and it's a high quality circuit breaker. ... show more

Performs exactly as expected. Excellent value for the money. Easy to install, very intuitive to use, easy to mount. Reliable and safe. I will purchase more units when I need them.

    • Read before buying!
Model: CB-03-300A
These are cheap and will probably protect a non critical, low draw load, but that is how far I would trust them. Beyond that I don't know. They are flimsy and will break if you over torque them. I did some testing on these and other cheap chinese versions and find that they did in fact trip more or less as expected within a larger than expected range. First off, remember, these aren't a fuse, they are a circuit breaker and their tripping or lack there of come down to several factors, including but not limited to: 1. Rated current 2. Ambient temperature 3. Tripping current 4. Tipping time 5. Tripping range And more factors than this. With a mild overload within the correct voltage range it can take an hour for these things to heat up and trip. There is something called a circuit breaker trip curve and an instantaneous trip amperage. All of this factors in. My issue with these is even in a controlled environment the tripping varied by almost 40%. This could be fine if it was always 20% at 25C for example. I could then predict and build accordingly however, it varied by 20% to 60% with seemingly no way to predict what was what. I was able to make use of the ones I bought, however, I had to build for broader ranges than I had hoped which meant increasing wire sizes in a couple of cases. Overall no big deal, but annoying none the less. I hope you found this helpful. ... show more

    • Used for a trolling motor
Model: CB-03-50A
These have worked great here.. There was originally one of those tube type fuses in the line for the trolling motor.. and when the trolling motor was pushed to full speed, or on high, the connections for that fuse heated up so bad that it melted the plastic around the fuse.. But it did not push enough power to actually blow the fuse.. It just got too hot from not a good enough of a connection from the springs to the tube fuse.. Which is why I got this to replace it.. It has worked great and we have had no problems so far.. It does not get hot any more either.. What is even better, since it is now a breaker and not a fuse, I do not have to worry about having spare fuses on hand either.. Well, for just in case since I never actually blew one on it.. So far, no complaints.. Very happy with the purchase.. ... show more
