Let Thru Curves

[burntcoil]

Can someone share the let-through curves for GE Current Limiting Fuses GF8B class L (800A to 2000A)
In addition I would like to ask how we can accurately read the logarithmic scale for the intermediate values for these let through curves.

Thanks

Not a lot of use for them anymore since UL and the NEC require series rated testing of assemblies for determining the adequacy of an under-rated device downstream. I don't have that model in my library.
Some still use them for control panel withstands. Is that your application?
