Mike, aren't these somewhat low in voltage rating? 230v?? they would short at switch-on with regular 240v present.....
Do you have deeper specs on their idle voltage versus spike voltage to indicate what voltage fluctuations these will handle?
I only ask this, because i've had to repair endless industrial equipment that some tech before me fitted out with 220v-240v MOVs, only to find all the machines blew fuses at powerup.
In that particular case i had to replace all the MOVs with the original versions being 300v rated according to the manual/tech guidlines.
Most pinny sites/mods i've seen have used the 275v versions for Aus.
Also to note, for anyone powering on a USA 110v pinny on 240, the MOV will short and blow the fuse...if there's any "sparks" it's just the mov+fuse exploding, NOT your pinny/boards ;-)
