I believe some 240V breakers require a neutral to power their internal circuitry, but there's no reason in theory that a GFCI breaker won't be able to pick up a ground fault on a system with no neutral.

It's conceivable that on a totally ungrounded system, a GFCI would not work, but that's different.
