Subject: [RE-wrenches] Complying with 690.9(B)

Hello Wrenches,

I have an inspector who doesn't like my heavy duty square D disconnect loaded with 20A Littelfuse FLSR RK5 Littelfuses for use as a OCPD and disconnect on a PV circuit.  I am operating below the 300Vdc rating for this fuse but I'm having trouble finding documentation that states that this fuse is listed for use in PV systems.
Does anyone know if these fuses have this listing for PV specifically?  Its not easy to find if they do.
Or perhaps a solar listed fuse designed for this disconnect?

If not, is there another disconnecting device that can work for this?  I am looking closely at the MNPV6-250 DISCO but again, the 300Vdc breakers that come with this are listed to  DC branch circuit protection (UL 489A, IEC / EN 60947-2) not necessarily calling out PV specifically.

Any input is appreciated!

Thanks
