REF610 is a feeder IED for protection, measuring and supervision of utility and industrial distribution power systems. REF610 is a member of ABB’s Relion product family and part of its 610 product series. The series includes IEDs for feeder protection, motor protection and 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 feeder protection IED, REF610, offers overcurrent and thermal overload protection, earth-fault and phase discontinuity protection for cable feeders, and three-pole, multi-shot auto-reclose functions for overhead line feeders. Enhanced with optional hardware the IED also features two light detection channels enabling arc fault protection of the switchgear, busbar system and cable terminals.
