For Ac line Surge protector 20d431k Mov is good or bad?

[@awesomedee5421]

How did you get such a high voltage from the power supply? and it seemed to be showing a DC voltage but your diagram was showing an AC voltage source. Does it matter?

[@sifatkabir2329]

He tested it with DC voltage because he had an dc high voltage generator and It’s cheap to buy. It demonstrated the behaviour or Varistor. It will work on AC as well.

That looks like a normal fuse not a thermal fuse
