Category: feeder protection relays
Country of origin: Sweden
Feeder protection REJ601
Basic series of digital relays for distribution networks

REJ601 is a dedicated feeder protection relay designed to protect utility and industrial power systems in primary and secondary distribution networks. The relay optimally combines protection and monitoring functions in a single unit, providing the best performance and availability in its class.

In addition to the traditional current transformer interface-based models, the relay also supports models based on the Rogowski current sensor analog interface. This helps achieve compact medium-voltage switchgear size reduction while improving performance and standardization.
