New motor protection to Relion® product family

ABB introduces a new member in the Relion® protection and control product family as part of its 605 series. The motor protection and control REM601 is a dedicated motor protection relay, intended for the protection of medium voltage asynchronous motors in manufacturing and process industry for both circuit-breaker and contactor-controlled motor drives. Recently, ABB also released an enhanced version of the feeder protection relay REF601 intended to be used for selective protection and control of feeders in utility and industrial power systems distribution networks.

These relays provide an optimized composition of protection, monitoring and control functionality in one unit, with the best performance usability in its class. They offer pre-configured functionality which facilitates easy and fast commissioning of switchgear.

The relays are available in various application configurations and feature optional communication functionality over MODBUS RTU and IEC 60870-5-103 protocol to customize different feeder requirements. The relays also provide multiple language options which enable user friendly HMI support. The relay uses conventional current transformers or Rogowski current sensors for measurement.

As a member of the Relion product family, REF601/REJ601 and REM601 share the same HMI look and feel as other Relion relays. For more information, please read the REF601/REJ601 and REM601 pages.
