I was having difficulty finding the voltage range of 600V for my solar system when I found these. I was a little concerned about the pricing, but they have bee performing flawlessly.

I recently installed this circuit breaker in my RV's solar PV system, and it’s been working great. The thermal magnetic trip feature provides reliable protection, and the DIN rail mount made installation quick and easy.The build quality feels solid, and it handles the load from my solar setup without any issues. It’s a compact and effective DC disconnect switch that gives me peace of mind. Definitely a solid choice for anyone working on a solar project.

I have a large 15kW solar installation consisting of three 5kW strings of panels. This switch is installed before the 10 guage solar run wires connect to my charge controller. The switch allows me to disconnect the DC power comming in from the panels when I need to work on the charge controller. I use a din rail to mount all my switches so this one fits nicely within my current setup. I've used the switch several times so far with no issues and it seems to be holding up nicely in my system. I've not testing the automatic "breaker" capability as I have no way to generate the 50+ amps of current to do so. I like the dual pole design as it disconnects both the positive and negative legs of the high voltage solar input.
