The RISH ELR VI series is a digital earth leakage relay designed to detect and protect against earth leakage current, over and under current, over and under voltage, and reverse power in single- and three-phase systems. It features a 4-digit 7-segment LED display, dual-color LED fault indicators, CBCT open detection, and True RMS measurement up to the 15th harmonic. Trip settings are programmable from 30 mA to 30 A, with configurable delays for all protection parameters. The relay supports two CBCT inputs for monitoring two loads simultaneously, stores the last 15 fault events, and offers auto-re-closure or manual reset via a front-panel button. Configuration is done via USB using the PRKAB interface. It complies with IEC 61010-1:2010 and IEC 61326 standards. The device is mounted on DIN rail.
