Why would they have 3 taps on the breaker?

Cutler-Hammer Type CHAF - One Pole Arc Fault. 15 amp.

Not sure what you are referring to as taps, but AFCI breakers, like GFCI breakers, have a terminal to which the hot conductors goes, a terminal to which the neutral conductor goes, and a white pigtail which goes to the neutral terminal bar.

Ron,

From the photo, there are two AFCI breakers side-by-side, I think the "3rd" white wire is actually to the other AFCI breaker. If not, that AFCI breaker is missing its 2nd white wire.
