Narrative:

ASR 9 radar failed for approximately 5 min due to what airways facilities tech called a 'blown circuit breaker'. Technicians were at the radar site at the time of occurrence. No reason was given as to what caused the breaker to fail when the question was asked. Controllers went to non radar procedures until cenrap went on-line. I suggest that the radar technicians have the answer as to how to prevent the situation from happening again.
