Rishabh Instruments Pvt. Ltd. Protection Relays & Systems RISH RELAY I-3-2000-HA

RISH Relay I is a three-phase current protection relay for over current, under current, current loss, and imbalance 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 indication. The relay has two independently programmable output contacts (1CO), auto/manual reset, and stores the last 15 faults. User-programmable CT secondary current range is 1 A to 5 A, with primary current programmable from 1 A to 999 kA. Adjustable time delays and set points are available for all protection functions. It complies with IEC 61010-1-2010 and IEC 61326-1. Auxiliary supply is 60 V to 300 V AC/DC. Maximum continuous input current is 145% of CT secondary, with less than 0.25 VA burden per phase and 4 VA total auxiliary burden. Accuracy is Class 0.5 under reference conditions of 23°C ±2°C.
