Does anyone on list have experience with the APC AP7920 switched rack PDU, or any of the horizontal rack mountables 
with management? We're looking at these for our remote sites.

So, that's not a very good endorsement :)

Idk why you'd use a fuse in a PDU.

MCB units age.  Especially with vibration.  A 10A MCB becomes a 9A MCB after some miles. 

Fuses don't. 

MCB units are good at protecting people since they trip quickly and aggressively. 

Fuses tend to linger before blowing, and thus are comparatively bad at protecting
people (longer shock) but better at protecting infrastructure (surge
and switch-on-transient resistance).
