FTU Relay
The FTU R200i Relay is used with Chardon Reclosers for both three-phase and single-phase models at 15kV, 27kV, and 38kV.
The FTU R200i Relay is a microprocessor based digital protection relay for use in Chardon Reclosers and which provides a wide range of protection functions, communication functions with MODBUS, DNP3, IEC 60870-5-104 and IEC 61850 protocols for integration with SCADA systems and implementation of automation in distribution systems.
