4. Product Introduction (Anti-Template)
The ABB REM615 is a dedicated motor protection and control relay from the Relion 615 series. It is designed for the protection, control, measurement, and supervision of asynchronous motors in manufacturing and process industry applications.
The relay provides the core motor-specific functions required during start-up and normal operation, including thermal overload protection, motor start-up supervision, locked-rotor protection, and protection against excessive starts. Additional functions typically include negative phase-sequence current unbalance protection, non-directional (and in some configurations directional) earth-fault protection, and backup overcurrent protection. The 615 series features a compact, withdrawable plug-in design and is engineered around the IEC 61850 standard for communication and interoperability. REM615 is commonly applied to circuit-breaker or contactor-controlled medium-voltage motors and larger low-voltage motors driving pumps, conveyors, crushers, mixers, fans, and similar equipment. Exact standard configuration, firmware version, and communication options must be verified when ordering a replacement.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full model designation (REM615), standard configuration code, firmware version, and hardware options (sensor inputs, arc protection, etc.). Photograph all labels.
- Functional Testing – Limited standalone testing is possible; full validation requires secondary injection testing and verification within the target protection scheme.
- QA & Packaging – Protect connectors and the withdrawable unit, clean according to electronics handling practices, and pack in anti-static protective packaging.
- Global Logistics & Export Compliance – Classify under the correct HS code for protective relays / IEDs. Packaging must protect against electrostatic discharge and mechanical shock; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
Configuration Matching – REM615 is supplied in different standard configurations. Ordering the wrong configuration can result in missing protection functions or incorrect I/O.
Firmware Version – Confirm the required firmware version for compatibility with the existing engineering tools (PCM600) and system.
CT/VT or Sensor Inputs – Verify whether the unit is configured for conventional instrument transformers or combi-sensors (Rogowski/voltage dividers).
Withdrawable Unit Handling – Follow correct racking and isolation procedures. Improper handling of the plug-in unit can damage connectors or the relay.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified REM615?
As a Relion 615 series protection relay, availability depends on configuration and surplus stock. Typical lead time after verification is 5–20 business days plus specialized shipping.
What is the primary function of this relay?
It is a dedicated motor protection and control relay for asynchronous motors in industrial applications.
What series does it belong to?
ABB Relion 615 series.
What are the main motor-specific protection functions?
Thermal overload, motor start-up supervision, locked-rotor protection, and starts-per-hour protection, among others.
What communication protocols does it support?
IEC 61850 (including GOOSE and process bus options), Modbus, DNP3, and IEC 60870-5-103, depending on configuration.
Is the relay still in production?
Yes. The Relion 615 series, including , remains part of ABB’s active protection and control portfolio. Specific configurations and revisions should be confirmed for availability.
What should be confirmed before ordering a replacement?
Exact model and standard configuration, firmware version, input type (conventional CT/VT or sensors), communication options, and compatibility with the existing protection scheme and engineering tools.
