Description

What is the correct DCin Fuse (F2) for the EBB SB2209 CAN? I need to replace my fuse but not sure what the full ratings and/or part to get. The old fuse has the marking "JF 10A"; assume that means it's rated for 10A @24V? The schedule lists F2 as 24V/4A. The CAD Step file shows the fuse with a 7A marking.

Which is the correct amp rating & max voltage? 10A, 7A, or 4A @24VDC? Shouldn't the fuse ratings/markings of the physical fuse, schedule F2, and the CAD step file match?

Can the exact fuse part number and/or full specifications be provided in the schedule?
