ABB REM610 is a legacy digital motor protection relay (discontinued 2017) for medium/low‑voltage asynchronous motors. It provides all‑in‑one protection, control, measurement, and supervision for motors across manufacturing, water, and power industries.

The REM610 offers comprehensive protection functions: thermal overload (with RTD option), locked rotor, startup supervision, overcurrent/short‑circuit, earth fault, current unbalance, phase reversal, undercurrent (loss of load), and circuit‑breaker failure protection. It supports 1A/5A CT inputs and includes a user‑friendly LCD for local monitoring.

Communication options include IEC 61850, IEC 60870‑5‑103, Modbus RTU/TCP, PROFIBUS DP, and SPA bus for SCADA integration. The plug‑in design simplifies maintenance, while the wide‑range power supply and rugged build ensure reliable operation in harsh industrial environments.
