Code permits the larger breaker downstream.
Does a 240V outlet need a neutral?
Most residential 240v-capable outlets are actually 120/240 and have a neutral to provide the 120v service. But your L6-30 (Or any 6- for that matter) is not capable of providing for 120v devices, and this means your load doesn't use neutral. So its GFCI protector doesn't need access to neutral either.
