well made but time will
very satisfied with these isolators. they do the job and seem to be well made time will tell how they work and i have not done any high current test to see if they trip at their specified level im 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 battery can recommend them

As good as or better than any other out there.
I have these in 6, 10, and 16A for a several years going back to 2021. Their non polarized feature is attractive to keep wiring from having to be looped to only one side. In the 4+ years of service I've thankfully not had a panel or load* failure but the breakers have never had an instance where they inexplicably went open. * I DID induce shorts on many of them purposefully to see if they actually would trip, and I had miscalculated the breaker value a few times for a particular load and they DID trip. I am 100% confident in them.

Good value, fast service
Used it on DC solar. Wish these were available in the standard size DIN breakers, instead of just the mini DIN size.
