Can you use a three-phase circuit breaker for a single phase load?

(OP)
I've got to hook up a small single phase control power transformer. I have a spare 480V 3-phase breaker in the control panel already wired in. I like it because it's a relatively expensive breaker that is monitored by a PLC. Is it legal to wire this this way?
