You might consider one of the zero crossover SSRs.  If your motor
application can tolerate the < 1/2 cycle delay, switching the motor off
while voltage is zero eliminates some of the transient current issues.
 Crydom has both random and zero crossover types within your specified
current ratings.  Digikey distributes a wide selection of Crydom SSRs.

Subject:        [PIC]: Solid State Relay -- >

Could anyone suggest a solid state relay that would hook to a pic for
controlling a 5 am induction motor? Would an opto22 work or ??? How would
you hook the diodes for flyback protection when the power is turned off? I
understand how to do this on a DC circuit but not AC.
Thanks in advance
