ABSTRACT:
A power cutoff circuit is added to the protector network disclosed in U.S. Pat. No. 4,675,772 so that when an interruption in power occurs, at least one suppressor remains connected to a load even though a source is disconnected from the load. In one embodiment, the power circuit includes a control circuit connected to the supply lines between an "upstream" suppressor and a filter portion of the network.
