Can I use a 208v three phase breaker for a 208v single phase branch circuit? The branch circuit will also be fused due to the three pole breaker being to large.
Yes... but it would be a feeder circuit if you fuse it down line of the breaker. The branch circuit would be after the fuse(s).

FWIW, the preceding is only true if fused at a lower rating than breaker. Fusing greater than breaker rating sends Code compliance scenarios out the window.
