REM610 is a motor IED for the protection, measuring and supervision of medium sized and large asynchronous LV motors and small and medium-sized asynchronous HVmotors in manufacturing and process industry. REM610 is a member of ABB’s Relion
® product family and part of its 610 product series. The series includes protection IEDs for feeders, motors and for general system voltage supervision. The plug-in design facilitates the commissioning of the switchgear and enables fast and safe insertion and withdrawal of IED plug-in units.
The IED can be used with both circuit-breaker and contactor-controlled motor drives in a variety of applications. Enhanced with an optional add-on card for RTD sensors or thermistor elements, the IED can be used for direct temperature measurement of critical motor items, such as bearings and windings. It is also used for the protection of cable feeders and distribution transformers benefiting from thermal overload protection besides phase overcurrent protection, earth-fault protection and phase unbalance protection.
The 610 series IEDs have been certificated for marine and off-shore use by Det Norske Veritas (DNV). REM610 supports IEC 61850, IEC 60870-5-103, Modbus®, Profibus, SPA and LON.
