1. DescriptionREM630 is a comprehensive motormanagement IED for protection, control,measuring and supervision of medium andlarge synchronous and asynchronous motorsin medium voltage industrial power systems.REM630 is a member of ABB’s Relion®product family and a part of its 630 seriescharacterized by functional scalability andflexible configurability. REM630 also featuresnecessary control functions required for themanagement of industrial motor feeder bays.The supported communication protocolsincluding IEC 61850 offer seamlessconnectivity to industrial automation systems.2. ApplicationREM630 provides main protection forsynchronous and asynchronous motors andthe associated drives. The motor managementIED is intended for circuit-breaker andcontactor controlled medium sized and largesynchronous and asynchronous motors in avariety of drive applications, such as motordrives for pumps, fans, compressors, mills,crushers, etc.The pre-defined configuration developed forREM630 can be used as such or easilycustomized or extended with add-onfunctions, by means of which the motormanagement IED can be fine-tuned to exactlysatisfy the specific requirements of yourpresent application.Motor Protection and Control 1MRS756977 DREM630Product version: 1.1 Issued: 2011-05-18Revision: DABB 3
