 Description

ABB designs REJ603 B1NN1NB44NNJ as a compact feeder protection relay for medium-voltage distribution networks and industrial substations. First, the REJ603 B1NN1NB44NNJ belongs to the Relion 605 series and delivers dependable feeder protection for secondary distribution systems. Moreover, the relay draws operating energy directly from current transformers, so the device operates without external auxiliary power.

As a result, engineers install REJ603 B1NN1NB44NNJ easily in remote substations, ring main units, and transformer feeders with limited power availability. In addition, the relay detects short-circuit conditions accurately and supports reliable earth-fault protection and feeder monitoring functions. Therefore, utilities improve system reliability while simplifying installation inside compact medium-voltage switchgear environments.
