Working on distribution systems up to 6000A and 24kV I had a little chuckle with the word "massive" to describe a 30A breaker...
However proud to be a Denali owner

Most power conditioners use one or more fuses, as you said, or thermal breakers. Both of these operate on the principle of progressive thermal heating. In other words as more current is drawn the temperature of the fuse or breaker element goes up until it finally trips. This heating creates thermal noise and is audible.
Electromagnetic breakers operate based upon an element that senses current without heating up. It can operate right at its maximum rating without heating up.
