Motor protection and control REM620 IEC

Compact protection and control for asynchronous and synchronous motors

REM620 is a dedicated motor management relay for the protection, control, measurement and supervision of medium- and large-sized asynchronous and synchronous motors in the manufacturing and process industry.


Scope

  • Protection for larger asynchronous and synchronous motors

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
