Description

The feeder protection relay REJ603 1.5 is part of the feeder protection series of relays, intended for the protection of secondary distribution network in utilities and industries. It is designed to be a part of Ring Main Units (RMU) and secondary distribution switchgears. The REJ603 relay is a self-powered numerical relay, which receives power from the main current transformers. This makes REJ603 1.5 an ideal choice for installations where an auxiliary supplies are not available, and it is suitable for unmanned distribution substations having no auxiliary supplies.
