ABB REM615 Motor Protection Relay

ABB REM615 Motor Protection Relay Overview & Key Features

The ABB REM615 ANSI is a dedicated motor relay engineered for the protection, control, measurement, and supervision of asynchronous and synchronous motors in generation plants and process industry applications. As a member of ABB's Relion product family and the 615 protection and control series, the REM615 combines a compact, withdrawable design with native IEC 61850 interoperability for modern substation automation environments.

Key Features

• Draw-out design that simplifies installation, testing, and field replacement without disturbing wiring
• Machine differential protection for early detection of stator winding faults
• High-impedance (HIZ) fault detection for sensitive ground-fault coverage
• Arc flash detection (AFD) with optical sensor inputs for sub-cycle arc-fault mitigation
• Ring-lug terminals on all inputs and outputs for vibration-resistant, reliable terminations
• Large, easy-to-read LCD for on-site parameter reading, event review, and diagnostics
• IEC 61850 native communication for seamless SCADA and multi-vendor substation integration

Practical Applications / How It Works

The REM615 is deployed where motor uptime directly impacts production output—pumps, compressors, fans, mills, conveyors, and other driven equipment in manufacturing and process plants. The relay continuously samples current, voltage, and (when fitted) arc-flash light intensity, comparing measured values against user-defined protection curves. When an abnormal condition such as overload, short circuit, ground fault, or arc flash is detected, the REM615 issues a trip command to the breaker in milliseconds, isolating the faulted section and preserving healthy downstream equipment. Its withdrawable construction enables fast swap-out during scheduled outages, while native IEC 61850 support eliminates proprietary gateways and simplifies future system upgrades.

Frequently Asked Questions

Q: What motor types does the ABB REM615 protect? A: The REM615 is designed for both asynchronous (induction) and synchronous motors, as well as their associated drives, in generation plants and process industry applications.

Q: Does the REM615 include arc flash detection? A: Yes. The relay has dedicated arc flash detection (AFD) inputs that work with point or loop-type optical sensors to detect and clear arc faults in sub-cycle time.

Q: Which communication protocols does the REM615 support? A: The REM615 is built on the IEC 61850 standard, enabling non-proprietary interoperability with modern substation automation systems, SCADA platforms, and other Relion 615 series IEDs.
