I was looking at some information for some commonly used (in NZ mains panels) Schneider din rail breakers and the following information caught my eye

This implies a relatively cheap source of breakers for common ebike voltages.
The C60N is available in 1, 2 and 3 poll (There is actually one of these in my new mains panel).
So by using polls in series they are apparently rated for DC at various voltage levels.
It looks like 1 poll for 48V or less bikes and 2 for up to 125VDC
There is an overrating factor so they trip at a different current for DC but that can easily be accommodated.
In the same document they also show how to calculate the breaking capacity based on the battery impedance pretty simple maths but nice they spell it out.
I might try one at on my bike some point but too many other things going ion at the moment. I would need to put it in a waterproof container.
Looks like they are capable of breaking 10 - 20KA or more depending of breaker and voltage/number of poles used but this is sufficiently high enough that they might be quite good in combination with LIPO as I think that it could easily handle LIPOs short circuit current.
The C120 Range may be even better as they go up to higher currents but probably with higher cost.
I would only do this with breakers where the manufacturer provides information that its ok such as above. I note they don't list the C60A breakers that are also in my panel so I would definitly goand get the C60N version.
