Details of ABB REF620 NBFNAANNDA1BBN1XF feeder protection device:

REF620 NBFNAANNDA1BBN1XF appears to be a specific model or identification of a feeder protection device. A feeder protection device is a device used to monitor and protect feeders (i.e. branch lines) in power systems. It usually has multiple protection functions to cope with different types of faults and abnormal situations, thereby ensuring the safe and stable operation of the power system.

The following are some common characteristics of feeder protection devices:

Fault detection: The feeder protection device can monitor real-time parameters such as current and voltage on the feeder, and determine the presence of faults based on preset thresholds.

Quick cut-off: Once a fault is detected, the feeder protection device will quickly cut off the power supply in the fault area to prevent the fault from expanding and damaging the equipment.

Selective protection: The feeder protection device usually has a selective protection function, which only cuts off the power supply in the fault area without affecting other normal operating areas.

Communication function: The feeder protection device may support communication with other devices or systems for remote monitoring, control, and diagnosis.

Multiple protection methods: The feeder protection device may support multiple protection methods, such as overcurrent protection, undervoltage protection, ground fault protection, etc., to meet different protection needs.

Automatic reclosing: In some cases, the feeder protection device may have an automatic reclosing function, which automatically attempts to reclose the disconnected switch after a fault occurs to restore power supply.
