Narrative:

In cruise we received a master caution and a flaps light on the cwp. We ran the QRH which directed us to select the flap setting that was indicated which was zero and turn on the [terrain awareness warning system] override. We used the tables to calculate a corrected ref for a flaps zero landing and a corrected landing distance which was ref 138 and just under 5;000 ft. We determined that a landing at destination would be ok because the runway is 7;000 ft long. We relayed a message to dispatch via operations to ensure that we were ok to land and briefed a zero flap visual approach. Operations relayed a message back to us that dispatch agreed and we were ok to land. We did not declare an emergency. We did not brief the passengers to brace. I briefed the flight attendant that we would be making an abnormal landing and we would be slightly faster than usual but there was no serious cause for alarm. I told her this was an abnormal situation; not an emergency. We landed without incident and taxied to the gate. Contract maintenance met us at the aircraft and determined that even though the flap indicator was indicating zero; we had some flaps down which is what triggered the caution. Maintenance trouble shot the problem and found a tripped circuit breaker. They reset the breaker; and checked the flaps for full range of travel and indication and checked that the cwp flaps light was out. It was a crew swap so I'm not exactly sure what the complete corrective action was but none the less the aircraft was signed off and made the return trip with another crew.

Title: SF340 Captain experiences a master caution and a flaps light on the CWP at cruise altitude. The flaps indicate up and a no flap landing at destination is planned and successfully executed. Maintenance found that some flaps were out and that a circuit breaker had tripped. Resetting the circuit breaker returned the flaps to normal operation.
