Claim 0:
1. In a power distribution system having a return line and an upstream breaker/fuse connected to a power line, an apparatus for protection from voltage transients, the apparatus comprising:
a transient voltage suppressor operatively coupled across the power line and the return line of the power distribution system to suppress voltage transients to a clamping voltage; and
a crowbar operatively coupled to both the return line and through the power line to the breaker/fuse of the power distribution system in a configuration to short the power line to the return line to open the breaker/fuse when the transient voltage suppressor fails to suppress the voltage transients to the clamping voltage, and
wherein the transient voltage suppressor fails to suppress the voltage transients to the clamping voltage when a voltage of the transient rises above a crowbar activation voltage, wherein the crowbar activation voltage is higher than the clamping voltage.
