Overview
Overview of EOCR-EGR Schneider Leakage Protector $r $nEGR-20UFCM Digital Grounding Leakage Fault Protection Relay adopts a new noise filtering function and has Modbus RS-485 communication function. It measures the vector sum of the three-phase main circuit in real time through an external zero sequence current transformer, and compares the vector sum current with the set leakage current value GR to determine the fault.
