ABSTRACT:
An alternating current circuit breaker having an extended fin cantilevered from its housing. A portion of the fin along its extended length is magnetized so that the fin flutters in the magnetic field generated by the alternating current conducted through the breaker. The resulting magnetic resonance vibration establishes forced, convective heat transfer which assists cooling of the breaker.
