60 Amp fuse Disconnect for a 50amp outlet

[ElectricPlugGuy]

Hi, can a 60a AC disconnect fuse box with 2 class K busman 50amp fuse work as a disconnect near the outlet ? Or would it need to be an actual breaker box, like an outdoor SPA GFCI breaker box?
The AC box says compatible with class H fuses. Class k and h are the same size.

I would think that the breaker that feeds it is sufficient enough. Actually it can be a non fusible disconnect. Have a great day and welcome to the forum.
