The EDR-3000 design provides true RMS (root-mean-square) value and fundamental sensing of each phase and ground current. Only one unit is required for each 3-phase circuit and the relay operates from the 5A or 1A secondary output of standard current transformers (CTs). The EDR-3000 features a user-friendly operations panel to monitor and program the relay, to reduce arc flash energy and offers Zone Selective Interlocking for bus protection.
Sensitive Ground Current: 0.5A/0.1A, Zone Selective Interlocking (ZSI) and IRIG-B, Communication: IEC-61850 (MMS and GOOSE), Conformal Coated Circuit Boards, Removable Terminals
