very satisfied with these isolators. they do the job and seem to be well madetime will tell how they work and i have not done any high current test to see if they trip at their specified levelim using them with a 200 watt solar panel on my truck with victron solar charger and inverter and 100 ah lifepo4 battery to run my camping fridge and led lighting.the main reason i wanted them is as isolating switches to the solar panel and solar controller to batterycan recommend them

These breakers seem to be well made and are about half to a third the price of other name brand din rail mounted breakers. Thumbs up.

I've purchased several of these, and can say that they feel more solidly built than most, trip when they should, and protect our solar system very well.
