I have this little terminal block here,  salvaged out of something (I
forget what),  with eight points tied to two bits of metal -- basically two
connections here.  The tie points are designed for those push-on
connectors, about 1/4" wide.

Soldered across two of these points is a part.  It sorta looks like a
ceramic capacitor,  but the color doesn't match that part -- it's black. 
Markings are a logo that vaguely resembles a triangle (or greek letter
delta?),  followed by "ZNR",  which leads me to believe that this
is perhaps a MOV.  Under that it says "10K24IU" or
"10K241U".  There's some more stuff below that that I can't make
out...

Anybody know what this is?
