Circuit breakers vs fuses
 

/www.chiefaircraft.com/cgi-bin/frame-aircraft.cgi?URL=/Aircraft/InstallationSupply/CircuitBreakers.html

I am thinking about replacing the fuses in my 99 TJ with push-pull type
aircraft breakers. I am going to make another overhead panel to hold the
breakers for easier access.

I plan to mount the breakers in a panel forward of the electrical panel.

Other than expense is there any other valid reason they uses fuses in
autos instead of breakers?

Re: Circuit breakers vs fuses
 

Unless you buy really expensive breakers, they are a lot slower than
fuses.

Things like stereos and computers and about any other electronic part
you want to name work best/safest when fused. By the time some IC chip
circuits see an overload big enough to pop a mechanical breaker, they
are long dead.

The breakers I am looking at run $14. to $22. each and are used to
protect avonics in aircraft.

I have seen PB relays in electronic circuits lots, but never have I seen
one of their circuit breakers used for electronics.

I also couldn't find any speed rating for them which implies they are
just regular breakers.

I sure wouldn't use them.

Re: Circuit breakers vs fuses
 

I will agree with Mike on this one. Why would you want to spend that kind
of money on a breaker setup? Are you buying that many fuses? If so, fix
the problem that's blowing fuses.

Re: Circuit breakers vs fuses
 

Hi Bill,

No doubt breakers are used in aircraft, boats (like my 270 SeaRay) and
commercial trucks. I guess it's for quick reset under emergency conditions.
When properly sized they can be nearly as effective as a fuse. The cost is
substantially more though.
