    300a version is no good
  

*by A***. on Reviewed in the United States on October 17, 2020*

Bought the 300a version, it shut itself off at 135a. Thought I’d damaged the breaker so bought another one — same thing. Have a 150a and a 100a and haven’t seen any issues with those, but the 300a version can’t even handle half what it’s supposed to.UPDATE: Seller contacted me asking me to take down my original review (above) in exchange for an Amazon gift card. My intention with my original review was to alert others of the problems with the 300a version of the Anjoshi surface-mount breaker, not to insinuate that you should avoid this seller or Anjoshi's other products, which is why I noted that I have the 150a and 100a versions of the same breaker and they work just fine.In fact, other than the bribe attempt, this seller has been great and I'd have no issues buying from them again.A friend of mine had the exact same experience with the 300a Anjoshi. Like me, he figured "a breaker is a breaker" and thought he'd save a little money by going with a cheaper one.I will not remove my original review, but I will expand on it a bit for those looking at 300a switch breakers, in hopes that maybe you won't lose hours and hours to a project like I did.My 3000w inverter kept shutting itself off and rebooting when my pull got to 135a. Like clockwork, test after test, 135a and shutoff. After 3 full days of troubleshooting and ruling out problems with the batteries, inverter and everything else we could think of, we tried some tests on the breaker. Didn't start there because the breaker wasn't popping and because we weren't even trying to pull half of what it's supposedly rated to handle.Turns out it was the breaker.Thinking maybe I just had a bad one, I returned it for another Anjoshi 300a surface-mount breaker. Had the exact same experience. So then I did a bunch more digging and went a different route. My system works perfectly now.I'm not a shill for another company or product, so I'm not going to recommend anything based on what I ended up doing. I'm just going to recommend that if you need a 300a breaker, do some research and call a few professionals who deal with products for your particular application, and then do what they suggest, which, at that amperage, almost certainly won't be a surface-mount breaker.

    250A Does not meet Continuous Rating
  

*by C***L on Reviewed in the United States on July 1, 2021*

I have a 2000W alternator. A 1500W load pulled ~110-120A. The 250A circuit breaker has two issues:1. There was a small load within the breaker itself at 120A load that caused ~.5V drop from the battery to load side. The longer the load ran, the larger the drop. Eventually the breaker had a partial? trip as it read 3-5V on the load side. After cooling off, voltage returned back to 12.5ish volts on the battery side. A .5V drop at 120A is basically telling me that this thing has a 60W load within the tripping mechanism itself, telling me its under strain to keep up with amperage draw.How do I know it was running 120A and 1500W? I have a victron smart shunt telling me the exact load the samlex inverter was pulling.To confirm my suspician that this is a poor performing breaker, I jumped the battery and load side of the breaker to bypass the tripping mechanism and everything worked fine.After only running the load for 2 or so minutes without the jumper, the circuit breaker was already above 100F in 60F outdoor temp.This breaker is dangerous. Do not buy.

    Okay with a few caveats
  

*by S***L on Reviewed in the United States on July 25, 2020*

I will say, this product works and its doing an excellent job for what I need - HOWEVER there are two glaring issues.1. The "reset" button is INSANELY sensitive.  If you so much as press carpet up against it (as in installing under carpet) it will be enough to press the button or cause a twitchy connection. I had to build a sheet metal cover for my switch because the carpet laying on top of it was enough to trip the button if the carpet shifted at all.2.  The grommets do not fit 4awg wire.  You'd think if you're going to advertise this as fitting 4 gauge wire, the "water tight" grommet should be able to fit 4 gauge wire, so I just had to use the open ended plastic caps which is no biggie to me.  Id be more upset if this breaker was exposed as then it would not look as finished as I would like.All things considered if you're placing this in a very safe place that has NO way of even being grazed near the button, and you're okay with the rubber grommets not fitting larger wires - its a good product for money.
