For 220-240VAC --
Should I use a 431 or 471 volt MOV?
What would be the difference in leakage current at 240VAC?

[@passiontechklm]

you can use either 431 or 471 for 240vac but for more safety 431 is more recomend to use which will protect more safe for your circut board.

[@arkapadma]

@@passiontechklm what about 20D391K vs 20D471K?

[@passiontechklm]

@@arkapadma 20D391 is more protective than 20D471 if you are using in 230vac circut board.

@@passiontechklm thanks a lot.

Is it still safe if we connect the varistor to L and N without fuse?

[@passiontechklm]

No safe, fuse is necessary calculated by load Amp since varistor is for surge protection so it must be both use .
