In what circumstances do they fail open versus low ohmic Specifically panasonic ZNR V10 241U A Yankee in Limeyland with a Makita fast battery charger misreads 110V~240W as 110V~240V and connects to 240V mains and a fatal sizzle. The transient suppressor , in there to suppress transients not sustained overvoltage, seems to have protected the electronics by going ohmic and blowing the 8amp internal fuse and part shattering itself in the process. But >8 amps seems to be a tall ask for such a small device, was he just lucky?
