E Series Relay - EDR-3000


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.
