DIHOOLSolar Disconnect Switch, 30 Amp 2 Pole, DIN Rail Mount, Non Polarized, 12V 24V 48V 400V, AC/DC Circuit Breaker, RV Battery Isolator, PV Array MCB, Thermal Magnetic Trip

I have purchased several of these for my solar generator builds. This is for a 12 volt system. This circuit breaker handles 30 amps. It is reliable, easy to install and not pricey.

2nd time purchasing this brand I'm very happy with the quality and performance so far at least that's my personal opinion. Came with wire furrels and a Din rail also.I upgraded to a 40amp breaker for my PV shut off and it's guaranteed for a yearI will be buying more when I'm doing the other phase of the project.

With this switch now I can shutdown all power going to my solor controller and battery bank with out pulling wires out each time I need to work on my system

Was easy to wire up and mount, but wasn't tight on the mounting channel. When you put the screws in the middle of the mount (at least on wood) it warps inward, which makes the breaker fit loosely. Didn't test the breaker part since I'm just using it as a disconnect.

Works as expected. Needed something that fits on DIN rail and they worked well for my project.

Comes with rail piece and screws. Well made.

Muy buena calidad

I wish the product, like many other DC breakers would say this in the product description, because apparently forums say DC breakers used for bi-directional charging/loads such as between batteries and inverters, and maybe even PV disconnects too, need to be non-polar. Because if a potential short circuit that happens on either end of the breaker won't heat it up. I really wish I knew more about this topic, but google "non-polar DC breakers" and you'll find more info. The one I bought is 120A, which I plan to use for at least one 100Ah battery. It's heavy, but I haven't installed it yet. It arrived quickly. I am hoping it works for the application I bought it for, but I purchased a 250A one also, for a larger string of batteries.
