The ABB REM610 is a compact, multifunctional motor protection relay engineered for dependable and intelligent safeguarding of low-voltage induction motors across industrial and utility environments. As a core member of ABB’s Relion® product family, the ABB REM610 unifies advanced protection logic, precise electrical measurement, and flexible communication capabilities into a single DIN-rail-mounted device. It delivers comprehensive defense against thermal overload, phase imbalance, locked rotor, short circuits, ground faults, and underload conditions—significantly reducing unplanned downtime and preventing motor damage.
Positioned as a cost-effective yet feature-rich solution within ABB’s motor management portfolio, the ABB REM610 excels where basic thermal relays fall short. It employs a sophisticated 7-segment thermal memory algorithm that accurately models real-world motor heating and cooling behavior, minimizing false trips during frequent starts or variable loading. Furthermore, the ABB REM610 supports remote monitoring and control through standard industrial protocols, making it a strategic enabler of predictive maintenance and energy efficiency initiatives in modern automation infrastructures.

Main Features and Advantages
Advanced thermal modeling for real-world motor dynamics: The ABB REM610 implements a 7-segment thermal memory algorithm that precisely tracks winding temperature during start-up, operation, and cooldown. This prevents nuisance tripping common with simpler relays while maintaining full protection against dangerous overheating—especially critical in applications with cyclic duty or frequent restarts.
Comprehensive protection in a space-saving design: Despite its compact size, the ABB REM610 offers up to 15 configurable protection functions, including ground fault detection (via residual current or external CT), phase unbalance, and underload monitoring for dry-run pump scenarios. Settings are easily adjusted via front-panel controls or ABB’s PCM600 engineering software, enabling application-specific tuning.
Seamless integration into industrial networks: Equipped with a standard RS485 port supporting Modbus RTU, the ABB REM610 provides real-time access to motor current, voltage, power, energy consumption, and event history. This data integrates directly into PLCs, SCADA, or energy management systems. Select variants also support native IEC 61850 for substation automation environments.
Robust construction for harsh environments: The ABB REM610 features reinforced insulation, high EMC immunity (±8 kV ESD, 4 kV EFT), and wide ambient temperature tolerance, ensuring stable performance in electrically noisy plants. Its self-powered design (in many configurations) eliminates the need for a separate auxiliary supply, simplifying wiring and reducing panel costs.
User-centric diagnostics and operation: A backlit LCD displays live measurements, trip causes, and configuration menus. Post-fault analysis is enhanced by a non-volatile event log storing up to 100 timestamped entries. The ABB REM610 also supports remote reset and self-test functions, improving maintenance efficiency and system uptime.
Application Field
The ABB REM610 is extensively used in industries where motor reliability directly affects production continuity and safety. In water and wastewater facilities, it protects pumps from dry-run conditions and mechanical jams. Within HVAC systems, the ABB REM610 ensures fans and chillers operate within safe thermal limits despite fluctuating airflow demands. In manufacturing—from automotive assembly to food processing—it safeguards conveyors, mixers, and compressors against electrical anomalies that could halt entire production lines.
The ABB REM610 is especially valuable in modernization projects, where legacy electromechanical overload relays are replaced with intelligent, communicative devices to upgrade motor control centers (MCCs) without panel redesign. Its compatibility with both new builds and existing control architectures makes it a versatile choice for system integrators and plant engineers. Additionally, in renewable energy installations such as biogas or biomass plants, the ABB REM610 provides dependable motor protection under unstable grid conditions. By transforming passive protection into an active asset management tool, the ABB REM610 enhances both operational resilience and energy intelligence.

Installation and Maintenance
Pre-installation preparation: Before installing the ABB REM610, confirm that the motor’s full-load current aligns with the relay’s selectable current input range (1 A or 5 A). Ensure correct CT polarity and proper grounding of the enclosure. Mount the ABB REM610 on a standard 35 mm DIN rail inside a ventilated, dust-protected switchgear cabinet. If using auxiliary power, verify it falls within the 24–250 V AC/DC universal range to ensure reliable startup.
Maintenance recommendations: Routinely check the ABB REM610 for warning indicators or communication errors. Perform an annual self-test to validate trip accuracy and response times. After any motor trip, review the non-volatile event log to identify root causes—this data is essential for predictive maintenance strategies. Keep firmware updated via PCM600 when integrating into evolving control systems. Although the ABB REM610 contains no moving parts and requires minimal servicing, periodic cleaning of terminals and display during panel maintenance ensures long-term operational integrity.
