Designed for sequential or systematic disconnect-reconnect. Housed in weather proof non-metallic enclosure. The Model 300 Series requires the Remote Detector Unit for operation. Designed for sequential or systematic disconnect-reconnect. When equipment is in normal operation and lightning is detected, the Model 300-C provides automatic and instantaneous equipment protection by simultaneously disconnecting and isolating the AC output voltage from its source and shunting the output connections together and to ground, for a period of time, then automatically restores all connections.
Operation is synchronized to a control voltage from a remote site.
Does not have a built-in detector.
