RISH Relay I is a three-phase current protection relay designed for over current, under current, current loss, and current unbalance protection in electrical systems. It features a 4-digit 7-segment LED display, True RMS measurement up to the 15th harmonic, and dual-color LED fault indications. The relay supports programmable CT secondary currents from 1 A to 5 A and primary currents from 1 A to 999 kA, with adjustable set points and time delays for each protection function. It offers selectable 3-phase 3-wire or 4-wire network configuration, auto/manual reset, and AND logic for combined fault triggering. The auxiliary supply is rated for 20-60 VDC or 20-40 VAC, with an input burden of less than 0.25 VA per phase and auxiliary burden under 4 VA. It complies with IEC 61010-1-2010 and IEC 61326-1 standards. The relay has two configurable relays (2CO) and is designed for mounting in control panels.
