REJ603 Relay – Selective Short-Circuit and Earth-Fault Protection for Distribution Networks

The REJ603 relay is designed for selective short-circuit and earth-fault protection in secondary distribution networks, providing reliable protection for feeders and transformers in both utilities and industries. This self-powered numerical relay requires no external auxiliary supply voltage, making it an ideal solution for remote installations where auxiliary power is unavailable. The REJ603 relay derives its power directly from the current transformers (CTs), ensuring dependable operation without the need for an external power source.

Primarily used in Ring Main Units (RMU) within distribution networks, the REJ603 relay offers enhanced protection with its ability to measure earth current either through internal calculations or by connecting to an external core balance current transformer (CBCT). This flexible design allows for precise earth-fault protection, ensuring the safety and reliability of critical distribution systems.

Choose the REJ603 relay for an efficient, cost-effective, and highly reliable protection solution for your distribution network and transformer applications, especially in locations without access to auxiliary power.
