Main Features and Advantages
Advanced motor-specific protection logic:
The REM615 HCMJAEADABC2BNN11E implements ABB’s proprietary thermal model that accurately simulates motor heating and cooling dynamics—preventing nuisance tripping during frequent starts while ensuring true thermal safety. Unlike simple current-based overload relays, it accounts for negative-sequence currents caused by phase imbalance, which can severely degrade motor insulation over time.
Native IEC 61850 with GOOSE messaging:
As one of the few compact relays in its class to support full IEC 61850 Edition 2—including GOOSE (Generic Object Oriented Substation Event)—the REM615 HCMJAEADABC2BNN11E enables ultra-fast interlocking and coordination between devices without hardwired signals. This reduces wiring complexity and allows substation-wide logic execution at millisecond speeds, critical for arc flash mitigation or load shedding schemes.
Integrated diagnostics and asset visibility:
Beyond protection, the REM615 HCMJAEADABC2BNN11E continuously logs operational data such as start count, run hours, trip history, and thermal capacity usage. These metrics are accessible via web interface or engineering tools like PCM600, enabling condition-based maintenance and reducing unplanned downtime. Disturbance records capture pre- and post-fault waveforms for root-cause analysis.
Compact design with high configurability:
Despite its small footprint (45 mm wide), the REM615 HCMJAEADABC2BNN11E offers extensive flexibility. All protection thresholds, time delays, and input/output logic are software-configurable—eliminating the need for multiple hardware variants. Its front-panel LCD with navigation buttons allows local commissioning without external tools, while password-protected access ensures security.
Global compliance and safety certification:
The REM615 HCMJAEADABC2BNN11E meets stringent international standards, including functional safety per IEC 61508 up to SIL2, making it suitable for safety-related control circuits. Its immunity to electromagnetic interference (per IEC 61000) ensures reliable operation in harsh industrial environments near VFDs or large contactors.
Application Field
The ABB REM615 HCMJAEADABC2BNN11E is extensively deployed in industries where motor reliability, energy efficiency, and system integration are paramount. In water and wastewater treatment plants, it protects submersible pumps and blowers from dry-run conditions, clogging-induced overload, and ground faults—common causes of motor burnout. Its phase-loss detection prevents single-phasing damage in remote pump stations with unstable power supply.
In manufacturing facilities, the ABB REM615 HCMJAEADABC2BNN11E safeguards conveyor drives, mixers, and extruders by detecting mechanical jams (via locked rotor) or belt slippage (via undercurrent). Integration with plant-wide Ethernet networks allows centralized monitoring of motor health through CMMS platforms, enabling proactive maintenance before failures disrupt production lines.
For commercial buildings and data centers, the ABB REM615 HCMJAEADABC2BNN11E ensures continuous operation of critical HVAC chillers and cooling tower fans. Its IEC 61850 compatibility simplifies connection to building management systems (BMS), while accurate energy metering supports ISO 50001 compliance. In mining and oil & gas, the relay’s rugged design and SIL2 capability make it suitable for hazardous area motor control centers (MCCs), where safety integrity and explosion-proof compliance are non-negotiable. Across all these sectors, the ABB REM615 HCMJAEADABC2BNN11E transforms basic motor protection into an intelligent, connected asset.

Installation and Maintenance
Pre-installation preparation: Verify that the REM615 HCMJAEADABC2BNN11E matches the system voltage and CT ratios before mounting on a standard 35 mm DIN rail in a well-ventilated enclosure. Ensure clean, shielded cables for current inputs, with shields grounded at the relay end only. Confirm that the Ethernet network supports IEC 61850 traffic prioritization if used in a substation LAN. Use ABB’s PCM600 software to load the correct configuration file—this specific model code HCMJAEADABC2BNN11E indicates pre-defined settings for 5 A CTs, English interface, and Ethernet/Modbus combo.
Maintenance recommendations: The REM615 HCMJAEADABC2BNN11E requires no routine calibration due to its solid-state design, but review event logs and thermal utilization trends quarterly via web interface or PCM600. Perform functional tests annually using a relay test set to validate trip accuracy. Keep firmware updated to benefit from cybersecurity patches and new diagnostic features. If replacing a legacy relay, the REM615 HCMJAEADABC2BNN11E’s compact size often allows direct retrofit without panel modifications—saving significant downtime.
