Box-Type FTU Feeder Terminal
Product Description
Primarily used for data acquisition, control, monitoring, and protection of outdoor pole-mounted circuit breakers or load switches, enabling telemetry, remote signaling, and remote control (three-remote functions) for pole-mounted switchgear. It also features communication capability with the distribution automation master station, transmitting collected data via wireless or fiber optic communication to the master station, and executing the master station’s regulation and control of feeders and terminal devices. It is typically installed on feeders.
