I just tested a 12/30 and got this:

Voltage (in Vac)        Current (out mA)
0                       0
20                      3.5
40                      8
60                      13
80                      18
100                     22.5
120                     28
140                     34.5

So it starts to limit just a tiny bit but not much at 140VAC.

Hmm, two responses, different answers. Any tie breakers? :)

     I would not expect it to.
     NSTs (as specified, here) are specialized, with magnetics
     designed to current limit at the nameplate value, or a bit over.
