I have used these  125A and they seem ok, they have quite strong blowout magnets inside for arc quenching, unlike other cheap brands.

Better and what I'm using now are these , a lot more robust and available in quite high currents.

Those cheaper rail mounted breakers have to be kept cool, by using 50mm^2 cable to act as a heatsink, don't place them in a small box or jammed in with others as they will get hot and trip prematurely.
