GREAT for those running high voltage solar panels -- a must have
They work with my 6S solar panel arrays (six panels in series VOC 300v DC, 3,000w). REDs on the left, BLACKs on the right. PV from the panels on top -- feeder lines on the bottom to the solar charger

Excellent DC breaker
excellent breaker, build quality is very good. one thing to note is that these do not have pre-defined polarity ( like others I have used ). you have to make sure top and bottom are the same ( hopefully an obvious observation ). I like these better than others I have used for DC projects ( solar ). Some have questionable ratings, these I don’t worry about.

Great replacement
It was easy to loosen the screws in the back and place it in to replace the old one that had overheated and no longer working.

Seems Sturdy Enough
I'm using this for switching and overload protection for DC current coming off battery connection at my solar charge controller.It feels nice and solid on the outside, and the hardware to lock down the connections seems okay. Not sure with bare Copper wire how the dissimilar metals will play together long-term, but I'm using this for a mostly seasonal application. The mounting rail feels like pretty thin Aluminum, so not sure how long that would hold up.It seems to be working fine, but I have not tried to do a load test up to rated amperage to trip the circuit breaker. I also put an inline fuse in that circuit, so hopefully at least have "enough" protections. 🤭

Red is hot Green is not
The media could not be loaded. I thought it's reverse. Installed the other night for my 600W solar array. Came home the next day finding out my battery was not being charged. And realize the little Insecutor window when it's red is hot. Green is tripped.

Great Product
I needed a way to disconnect my solar panels and my battery in my camper from the controlling unit so I could remove the battery and shut the system down in the winter. These worked perfect for that. The camper should have come from the factory with these already installed since the camper came with solar panels, but it didn't. Just a way to save a few dollars.

Great for Solar Panel Disconnects
I have 2 of these ( 1 for each bank of solar panels). One bank gets sunshine in the morning and the other gets sunshine in the afternoon. These 2 banks will fight each other if you combine them so you need a charge controller for each bank.

seems good
better quality than other din breakers I have boughtunit doesn't give when tightening screws other I have bought would have to hold case as they seemed to want to spread casing these do not
