Product Introduction
ABB REM610 is a numerical feeder protection relay in the REL610 family, developed for medium-voltage feeders in industrial, utility, and substation applications. It provides multi-stage overcurrent, earth-fault, and thermal protection, with configurable breaker failure supervision and interlocking logic for complex feeder schemes.
The relay communicates via IEC 60870-5-103 and optionally Modbus RTU, allowing integration into SCADA and substation monitoring systems. New Surplus units undergo rigorous QC: serial verification, insulation resistance testing (>10 MΩ at 500 V Megger), full I/O functional testing, and firmware version confirmation to ensure reliable operation in the field.
