ABB REM620 Arc Flash Protection Relay

ABB REM620 Relay Overview & Key Features

The ABB REM620 is a dedicated motor and arc flash protection relay from the Relion® 620 series, engineered for the protection, control, measurement, and supervision of asynchronous and synchronous motors in manufacturing and process industry applications. Built on ABB's Relion® platform, the 620 series leverages the IEC 61850 standard for interoperable substation automation, enabling direct communication between intelligent electronic devices (IEDs) without proprietary gateways or protocol converters.

Key features include:

• Comprehensive motor protection for synchronous and asynchronous motors, including units paired with variable frequency drives
• Native IEC 61850 communication for interoperability, simplified engineering, and reduced wiring complexity
• Integrated arc flash detection that reduces personnel hazards and limits equipment damage during fault events
• Multi-function control, measurement, and supervision consolidated into a single compact IED
• Safety-conscious design aligned with arc-resistant switchgear installations
• Streamlined system upgrades without rewiring or replacing existing components
• Reduced operating costs through effective energy management and condition-based maintenance strategies

Practical Applications & How It Works

The REM620 is deployed in motor control centers (MCCs), switchgear rooms, and process skids where reliable motor starting, continuous running, and rapid fault clearing are critical. Typical use cases include pumps, compressors, conveyors, fans, mixers, and mills in chemical processing, oil and gas, water and wastewater treatment, pulp and paper, mining, cement, and metal processing facilities. The relay continuously monitors current, voltage, and thermal motor models in real time, triggering protective trips, alarms, and breaker commands when operating parameters exceed safe thresholds. Its arc flash protection function interfaces with optical point or loop sensors to detect the characteristic light signature of an arcing fault and issues a sub-cycle trip command to the upstream breaker, clearing the fault in milliseconds and reducing incident energy exposure to operating personnel.

Frequently Asked Questions

Q: What types of motors does the ABB REM620 protect? A: The REM620 protects both synchronous and asynchronous (induction) motors, including machines driven by variable frequency drives, across manufacturing and process industry applications.

Q: Does the REM620 support modern substation communication protocols? A: Yes. As a member of ABB's Relion® 620 series, it provides native IEC 61850 support for seamless interoperability with other substation automation devices, eliminating the need for proprietary protocol converters.

Q: How does the arc flash protection function operate? A: The relay interfaces with optical arc sensors to detect the characteristic light signature of an arcing fault. Upon detection, it issues a fast trip command to the upstream breaker, clearing the fault within milliseconds and reducing incident energy exposure to operating personnel.
