F-RLY Feeder Protection Relay for Recloser

Price: $1500

The Feeder Protection Relay for the recloser is used for the overhead line & cable line Primary Switch. It is a comprehensive indoor outdoor automation control device that integrates line protection, control, measurement, and monitoring of voltage and current signals. This feeder protection relay can be configured with various distribution automation logic, and be compatible with multiple communications like IEC61850 communication, GOOSE, DNP3 (TCP/IP), IEC 60870-5-104/101, and Modbus communication protocols.

This F-RLY feeder protection relay for recloser has two types: F-RLY100 feeder protection relay and F-RLY200 feeder protection relay. It is suitable for outdoor switchgear up to 10kv -40.5kV, including vacuum circuit breakers, oil circuit breakers, gas circuit breakers, and reclosers. Both of them have the following common features.
