During descent with the thrust lever at idle only a B737-300's nose gear red disagree light illuminated; then during approach the configuration warning alerted with the gear extended; flaps greater than 5. The landing gear circuit breaker was discovered tripped; and the system returned to normal with its reset.

Narrative:
On visual approach; after landing gear was put down and flaps 15 called; an intermittent warning horn sounded with only a red light for the nose gear. Gear felt and sounded like they were down. Called for go-around; told tower; and he switched us over to departure. Ran gear disagree checklist; but it did not help our problem. Then found gear circuit breaker popped. After reset; had normal gear indications. Approach and landing normal. Conferred with maintenance at gate who called moc. Since this was a first time occurrence; an info writeup was put in the log.possibly could have saved time if check the gear circuit breakers was in the checklist. I know it is in the manual to check them for problems; but a night go-around caused by an unsafe gear indication with a lot of traffic; a little reminder is appreciated.
