Can a DNO Service Cut-out be used as the primary source of fault current protection, when the DB it supplies is more than 3m from the intake?

I attended a site where the DNO (100A 1361) feeds a 100A Sw/ disconnector (with solid un-fused links) this then supplies a DB located in an adjacent room with 100A 60947-3 main switch.

Is this acceptable as the only fault current protection is afforded by the DNO.
