I made the mistake of trying to use a couple breakers like the one in the OP photo that I purchased off Amazon. One was rated 250 amps the other 200, both different brands. I got them instead of fuses, or quality breakers to use for my 2000 watt inverter. I'm not sure what the rating is supposed to mean, evidently some very short duration transient current flow or some sort of different Chinese electrons or something.
In trying to run my coffee pot, trimetric showing I'm pulling about 74 amps of DC current, the 250A breaker tripped in under a minute. Tried the setup again, same results. Next, after once again waiting quite awhile to let the CB cool, just for fun I fired up the microwave which pulls about 165A on the DC side. The CB tripped in a couple seconds. I then swapped in the 200A breaker which was intended for another purpose and it didn't even maintain the coffee pot load for 30 seconds. I ended up using good old fashioned cheap amazon fuses and haven't had a failure yet.
On the other hand, I have one of the inline fuse holder looking versions in line for my 600 watt inverter. It's rated at 80A and to date has never tripped on me yet, even though I have overloaded the inverter once to where it shut itself down. Of course I haven't actually tried overloading it to see if in fact it will trip.
