Narrative:
Due to miscommunication with ATC we were high on approach to the runway. No problem really as weather was at least 3;000 overcast and visibility 10 plus miles. On contact with tower at three miles out and 1;500 MSL we asked for a 360 degree turn to reacquire the profile. Still not a problem as they approved a right turn. As I was in the turn tower then commanded a left turn; as I rolled out spotted traffic below at 11 o'clock and low. At that time a TCAS RA commanded a climb as traffic was about 2 miles and 200 ft below us. Responded to RA and initiated a climb. Passed traffic with about 400 ft separation. Reacquired final and landed normally on the runway.
