CFT-380
FTU Recloser Controls
Recloser controls are the front line of the distribution power system, often located on feeders or in distribution substations. Recloser controls supply the intelligence to the network and handle the network protection and in many cases even the RTU functionality.
Feeder Terminal Unit Voltage Distribution Automation
The CFT-380 feeder protection can be used for protection and automation of medium voltage distribution feeders with grounded or low resistance grounded, isolated, or compensated neutral point.
CFT-380 multifunctional FTU offer a comprehensive solution for protecting and controlling distribution reclosers or sectionalizers.
Besides the main protection functions, they include monitoring and operation features as well as logic programming, and events and fault reporting providing comprehensive switchgear (circuit breaker, recloser or LBS) management local and remote capabilities.
CFT-380 is a cost-effective solution for protection and control systems for which IEC 61850 standard compliance is required, including access in other protocols and web services as well.
