It’s one of those things that becomes the subject of AHJ interpretation;
Fused, yes, because you may need to test for a blown fuse, and/or replace it. Circuit breakers too, because you may need to open the door to test and/or reset.
Best is to ask your local AHJ for their opinion before proceeding, you don’t want a surprise.
A lot of AHJs I have encountered over the years do not consider non-fused disconnects as being in the category of the highlighted section (ignore the blue, couldn’t get rid of it…).(A) Working Space
Working space for equipment operating at 1000 volts, nominal, or less to ground and likely to require examination, adjustment, servicing, or maintenance while energized shall comply with the dimensions of 110.26(A)(1), (A)(2), (A)(3), and (A)(4) or as required or permitted elsewhere in this Code.
