Products Description
ABB REF615E Relion Feeder Protection Control Relay Unit

Feature & Principle
This intelligent electronic device collects current and voltage signals from CT/PT. It executes overcurrent, earth fault, overvoltage, undervoltage and frequency protection functions, sends trip command to circuit breaker when fault occurs. It provides local HMI and web HMI for parameter setting, alarm check and fault record review, and exchanges real-time data with substation SCADA system via Ethernet.
