Overview of the ABB REJ603 Numerical Relay

The ABB REJ603 Numerical Relay is a state-of-the-art solution designed to revolutionize power distribution and management systems. It integrates advanced numerical protection functions with a user-friendly interface, offering unprecedented reliability and flexibility in safeguarding electrical networks. Unlike traditional relay systems, the REJ603 leverages cutting-edge technology to provide real-time monitoring, fault detection, and rapid response capabilities, ensuring the optimal performance and protection of critical assets.

The ABB REJ603 numerical relay is specifically engineered for entry-level protection in secondary distribution networks. It’s adept at providing selective short-circuit and earth-fault protection for feeders within these networks, as well as offering protection for small transformers in utility and industrial settings. Designed to operate without auxiliary power, the REJ603 is particularly suited for installation in remote locations where power availability may be limited or uncertain. Its primary applications include integration into ring main units and secondary distribution switchgear within distribution networks. The relay comes in two variants, 1.5 and 3.0, catering to different types of current transformers—special for variant 1.5 and conventional for variant 3.0.

Product Benefits Of ABB REJ603 Self-Powered Feeder Protection

  • Utilizing the front USB port for power negates the necessity for an onboard battery, while also granting access to event and fault information even in instances where CT power is unavailable.
  • High suitability of operation with low-energy trip coils
  • Quick commissioning is facilitated by the selective test function, which allows for testing of protection functions and binary output contacts, including the ability to perform test trips to the circuit breaker.
  • Fault analysis with event log/disturbance record facility (3.0 variant)
  • Extensive self-supervision of relay hardware and software
  • Built-in hand-reset electromechanical flag

Key Features Of ABB REJ603 Feeder Protection Relay

  • Non-directional overcurrent, earth-fault protection, thermal overload protection, inrush current detection, remote trip and measurements
  • Disturbance and event records can be easily downloaded from the front USB port, which also serves for communication between the relay and a desktop or laptop PC, or even a power bank. The USB port enables the relay to function even without current input, serving as a power source in the absence of auxiliary power (variant 3.0).
  • Low-energy trip output and bi-stable outputs to trip circuit breaker
  • Designed for Ring Main Unit (RMU) and compact switchgear
  • Deployed in cable or transformer feeders within solidly earthed, resistance-earthed, or isolated networks where auxiliary power is either unavailable or uncertain.
