Anyone replaced Fuse with Circuit Breaker?

someone else with the same question......and some test equipment.

interesting conclusions.

JUST like MOV devices in surge protectors, Circuit Breakers 'age' poorly and change with repeated cycling. Other articles testing really HUGE breakers say calibration is needed after a trip.

Read the conclusions of the article I cited. Time lag may not be an issue. Besides, if it were, you'd still have possible replacement for Slo-Blo on the table.

and though, like the rest of us HIFi is right and wrong at different times and to different degrees, the 'How often does the fuses in your amp fail?' remark is spot on.
Are breakers a solution in search of a problem?
Since I've NEVER blown a fuse in my panels, I'll eventually do some wiring changes to both simplifiy and eliminate the fuse. Problem solved.

And don't forget that their is another class of fuse which is VERY fast acting and used to protect delicate semiconductors in certain applications.

Personally, I'll stick with fuses. Inexpensive, reliable and need no special attention.

Breakers make perfect sense in some applications. A breaker can be used to shut off an entire circuit....use it as a switch, maybe.

Private planes don't generally need electricity to fly but DO use plenty of power for avionics. The spark plugs are fired by Magnetos, maybe still. I've seen commercial with an extendible air powered genset to provide minimal power to controls in the event of a catastrophic power fail. A similar unit is STC'd for several planes as an add-on. (STC=supplimental type certificate)
