Scope

• Protection for larger asynchronous and synchronous motors

ABB REM620 IEC Key benefits

• Extensive protection and control functionality, either with sensors or conventional instrument transformers
• Functional scalability and extensive possibilities to easily tailor configurations to application-specific requirements
• Withdrawable plug-in unit design for swift installation and testing
• Large graphical display showing customizable SLDs, accessible either locally or through an easy-to-use web-browser-based HMI
• Extensive life-cycle services

Key features

• Extensive motor protection for medium- and large-sized asynchronous and synchronous motors requiring differential protection
• Motor protection both during motor start-up and normal run, with protection and fault clearance in abnormal situations as well
• Additionally extensive motor supervision capabilities via RTD and mA measurements and optionally arc protection
• Supports native IEC 61850 Editions 1 and 2, including redundancy HSR and PRP, GOOSE messaging and IEC 61850-9-2 LE for less wiring and supervised communication
• Supports Modbus, DNP3 and IEC 60870-5-103 communication protocols and different time synchronization methods, including high-accuracy time synchronization via IEEE 1588 V2 Precision Time Protocol
