I know from personal experience as well that you can zap those SSR in a
heart beat. Zapped both the primary side and stepstart SSR in my small amp
when I had a tube glitch. Those were new (and expensive) Crydom 50A/480V
units. In my case, they both failed in a shorted condition.
Sure the sex and sizzle of the SSR is not in question. But the risk of
failing in a shorted condition seems to me a serious problem if they are
expected to be relied on as part of a protection function.

Quoting KA4INM <ka4inm@gmail.com>:
and an instant disconnect if the protection circuit detects too much
screen current or a sharp increase in (negative) power supply current
(an arc) surely make them well worth bothering with.
