• Model Info: REF620E_F (base model); Ordering Code: NBFNAANNNCC1BNN1X; Relion® 620 series member
2. Protection & Control Functions
This relay is equipped with a high - performance industrial - grade processor and advanced algorithms, providing comprehensive protection functions such as overcurrent, earth fault (with high - sensitivity multifrequency admittance - based detection), overvoltage, undervoltage, frequency deviation and arc flash protection. It supports control functions including auto reclosing, load shedding, synchronization and circuit breaker control, and can quickly locate short - circuit and earth - fault points for efficient fault isolation. The protection logic is configurable, and users can tailor the settings according to specific application requirements to ensure the safe and reliable operation of the feeder system.
• Protection Functions: Overcurrent, earth fault, overvoltage, undervoltage, frequency, arc flash, etc.
• Control Functions: Auto reclosing, load shedding, synchronization, circuit breaker remote control
• Fault Detection: Multifrequency admittance - based earth - fault algorithm; precise fault location
