George: Not to put too fine a point on it but ZNRs are large and slow
moving
so they do have mechanical aspects but more to the point they do NOT
have
capacitance, save lead capacitance (a few pf),
Not true: MOVs have a self-capacitance on the order of 1000pF, which is
sometimes an advantage.
I just did one of the dumbest things I've done since I tried to swim
across the Susquehanna river with all my clothes on. I survived that,
but I need help with something else.
I just turned on a computer plugged into 230v with the switch on the
power supply set to 115v. Result: bang, smoke,
Hi,Typically a device labeled as znr is a MOV, metal oxide varistor used to
protect cir u its from excessive voltage or currents. Remove the other one, you
will probably find a marking.

Took the second one out. It is labeled TVR07241, which is a 240v
varistor! I can get these to replace them.
I think this one is undamaged (at least, it isn't blown up or shorted).
I wonder if the other one was a 115V one which

There is nothing mechanical about a ZNR. The electrical equivalent is back to
back Zener diodes with a capacitor
a Zener.
