ABB REJ603BB401NN3XE REJ603 Self-Powered Feeder Protection
Brand ABB Model REJ603BB401NN3XE REJ603 Introduction: REJ603 relay is intended to be used for the selective short-circuit and earth-fault protection of feeders in secondary distribution networks and for protection of transformers in utilities and industries. The relay is a selfpowered Numerical relay, which does not require external auxiliary supply voltage, making it an ideal choice for installation even in remote locations where auxiliary supplies are not available. The relay derives power for its operation from the current transformers. REJ603 is primarily used in Ring Main Units ( RMU ) within distribution network. Relay provides earth current measurement through internal calculation or has the provision for measuring it from the external core balance current transformer (CBCT). The key features of the relay are: Self-powered three phase non-directional overcurrent and earth-fault protection with DMT and IDMT characteristics Dual mode of earth fault measurement - internal vector summation or external CBCT input Integrated IDMT curves (IEC and Special) in a single product to cover time co-ordination needs of secondary distribution protection Protection blocking by second harmonic measurement for stability during magnetizing inrush of transformers Capacitor discharge impulse output for low energy trip coil Built-in hand-reset electromagnetic flag for trip indication Easy setting by DIP switches, protected by a transparent cover Compact design and mounting arrangement suitable for Ring Main Unit (RMU) / secondary switchgear applications Test facility for testing entire scheme including primary CT, relay and trip coil Signal output for trip indication to external system Why choose us？ ☑ Thousands of suppliers and extensive product ranges make you experience a one-stop shop. ☑ Best quality products. ☑ Most product warranty of up to 1 year, any quality problem is returned at our cost.
