I think most of he vulnerable items would fry at nearly the speed of light; realistically too quickly for a reaction to help.

A big honkin' diode across the inputs - reverse biased normally - would act like a short in a RP situation and perhaps trip the main breaker while dropping the voltage to a less harmful level. Needs to handle several hundred Amps for many milliseconds.
