Protecting Expensive Electronics
 

Hey guys came across this while doing a Google search of "overvoltage relays".

I would like to know what the net-wisdom is on overvoltage relays or crowbar protection circuits & polyfuses.

Specifically, installing another overvoltage relay, crowbar protection circuit, and/or polyfuses to protect expensive electronics.

These links make some good reading:
