Musktool- F-FTU200L Feeder Terminal Unit
Product Overview
| The F-FTU200L is a critical component in distribution grid automation, designed to enable Fault Detection, Isolation, and Restoration (FDIR). It reduces outage time, improves power supply reliability, and integrates seamlessly with SCADA systems to achieve "four-remote" functions (remote signaling, telemetry, control, and regulation). Compatible with IEC/ANSI standards, it supports Load Break Switches (LBS) and offers versatile automation solutions for overhead lines. |
