I've seen delay timers on central AC, and some commercial
AC. Never seen delay timers on refrigeration equipment.

Most AC and refrigeration equipment have a delay that
usefully takes
up to 5 min or more after power is interrupted, allowing the
pressure
in the compressor to equalize. If the pressure is not
equalized it is
likely that the compressor will try and start, but instead
draw a
large current and trip whatever high current device there is
in the
system. It is not desirable not to use the high current
limiting
device as it can shorting the life of the compressor.
