Diazed fuses on DC

[Skogsgurra]

Is there any data available regarding Diazed fuses and how they can be used in a DC grid with around 300 V DC and unlimited Isc?

Can find data for US cartridge fuses, but not for Diazed. Also, there is no AC or DC mark on the fuses. Does that mean that they are equally good on both currents?

A somewhat oblique answer: Cooper Bussman's range of D-type (Diazed) fuselinks are clearly marked 400V AC / 250V DC on the body of the fuselink. So it would appear that they do have DC breaking capability, but at reduced voltage.

Don't take the above as gospel: the fuselink could be a Neozed type, which is slightly different.
