Hi,

Thanks for such good info.

BTW: When an MOV fails due to being unable to dissipatge too many Joules,
or overcurrent, how does it fail ? As an open or as a short between the
lines it was trying to protect ?


These short the line so that the fuse blows out, thus effectively
disconnecting the load from the power source.
