The feeder protection relay REX 521 is designed for protection, control, measurement and monitoring in medium voltage networks, as well as protection of medium to large three-phase AC motors in circuit breaker control motor drivers. Typical applications include feed, discharge and motor feeders and substation protection. In addition, the relay can be used as backup protection for power transformers and backup protection for high-voltage line protection relays.


Protective relays are equipped with energized inputs for conventional current and voltage transformers. In addition, hardware versions with current and voltage sensor inputs are available.


The REX 521 feeder protection relay is further enriched with additional features to provide more efficient protection, expanded measurement, monitoring, control and connectivity for your power grid. REX 521 is primarily used in single-bus solutions, using a single circuit breaker for various protections.


With prefabricated standard configurations, the unit can be used in different types of networks, with typical applications including input and output feeders in radially isolated neutral, resonant grounded, solid grounded and resistance grounded systems.
