Your system is 100V, so you can use AC switches/fuses, but mine is 60V.
The switch I have would work perfectly well in your 60v system. The fuse socket came with the switch so the fuse is there just to complete the circuit. The switch is double pole single throw so both + & - from panels is disconnected.
It is 30a 240vac rated. I really doubt 100v 8adc will cause any issues.
