Just so.
(I've sundry 100-1910 wireless books, with extended
technical description of Wehnelt (and otgher) interrupters.)
Wehnelt was designed for (relatively) low voltages.

Wellllllll.
They could and did handle large powers, via large amps.

I'd doubt a 'bomb', as such. I'd expect it to just not
interrupt to speak of.
Anyone working with a Wehnelt is advised to plan for
when (not if) the Sulfuric Acid gets loose, gets sprayed
about, etc.
