ABB REJ603 | Numerical Relay for RMU & Secondary Distribution

ABB REJ603 | Numerical Relay for RMU & Secondary DistributionProduct Overview The ABB REJ603 (Part Number: 1VYV91248286) stands as a specialized numerical relay within the Relion 605 series, engineered specifically for secondary distribution switchgear and Ring Main Units (RMUs). This device utilizes a unique self powered design, drawing operational energy directly from the feeder current transformers. By eliminating the dependency on external auxiliary power supplies, the REJ603 ensures reliable protection in
