I'm converting a VW bug to Nissan Leaf power. I understand the Leaf came with a 450V/225A fuse and so I'm looking for something similar online.
I came across the Bel 0AKN series of fuses, which are described as "electric vehicle power fuses." The spec sheet is at
https://www.mouser.com/datasheet/2/643/ds_CP_0AKN_series-3006958.pdf
These fuses also happen to be half the price of a similarly spec'd Ferraz Shawmut A50QS250, so I'm wary. Neither are offered by the like of EV West, Zero-ev, Evolve Electric, etc., further adding to my suspicion.

Any wisdom from the community?
Thanks
