There is quite a price difference, but what is the functional difference
between HVAC breakers and standard ones?

I didn't know there was any difference. I use standard breakers in my
panel for my A/C unit; always have.

A standard 240-volt, single phase breaker is a breaker. If the breaker is
the right size for the HVAC equipment then it will work.

I have never seen a HVAC breaker, maybe a three phase breaker?

"HACR" breaker.

Scroll about half way down.

The mfr listing for the equipment will determine the
OC protection which *must* be used.

Sounds like BS. Never heard tell of such a thing. Use standard breakers
for the a/c and furnace, then go out to dinner and not worry about it.

Probably only the UL listing. If the nameplate says use HACR circuit
breaker, then that is what is required.

Allows a brief current surge, for starting the motor. As opposed
to a breaker for other things, which trips more quickly in case
of over current.

Quit posting on things you know nothing about.

John has the right answer. Fortunately most modern molded case
breakers are rated HACR these days so a "regular" breaker is probably
fine.

The 2 main differences between a square D hvac breaker and a standard square D
QO series breaker is The way it mounts. A standard breaker is powered through
the mounting clips and sends power through lugs .. HVAC breakers have lugs
for incoming power on bottomband lugs or spade blades on top to distribute
power. These are typicslly found on air handlers with heat strips and are used
instead of fuses..

You are confusing HCAR rated breakers and QOM breakers that bolt to
the bus. Any breaker can be backfed if you use the supplemental
retainer clip (or a screw in some styles)
