New way of E-Bike protection ( automatic fuse )

Well I tried using a 220v AC 32amp circuit breaker but even at a peak of 100a it won't break :(
And a few seconds at 80Amp it also won't break, maybe because it needs 220v AC ?

I have a similar breaker, rated at 25A, 240V AC / 48V DC, and my lipos are
50V hot off the charger (12s). Can i use that breaker? My controller is set for 20A max,
and breaker would be used as fuse and main on/off switch.
I dont know how to test when will it break (well, i do know in theory, use wattmeter,
and some load and look, but i dont own wattmeter, and load would probably cause problems too...).
