Self-Powered Feeder Protection ABB REJ603BB401NN3XE REJ603

High qualityABB REJ603BB401NN3XE REJ603

REJ603 is designed for selective short-circuit and earth-fault protection of feeders in secondary distribution networks and for protection of small transformers in utilities and industries. REJ603 is a current-transformer-powered numerical feeder protection relay designed for applications where auxiliary power is not available or cannot be guaranteed, thereby making it an ideal choice for installation at remote locations. The relay is primarily used in ring main units and secondary distribution switchgear within distribution networks. Relay variants 1.5 and 3.0 support special and conventional current transformers respectively.
