Ken,
I really don't think specifications about fuses and circuit breakers
is the significant point. It makes sense that the fuse could be
quicker than a circuit breaker, still, that is not the point.
The point is that the engineers of Ten Tec found the AirPac circuit
breaker to be sufficiently fast to protect the radios that they designed.
