Product Detail

ABB REF610 retired feeder protection IED provides full feeder fault protection, measurement and communication for medium voltage power distribution.

Part No: REF610
Brand: ABB Relion 610 series
Status: Officially discontinued since 2017, only aftermarket spare availableABB Group
Type: Numerical feeder protection relay / distribution IED
FunctionSafeguard incoming and outgoing feeders in industrial and utility substations. It monitors line current, voltage and operation status, triggers circuit breaker tripping against short circuit, overload, earth fault and phase loss faults. It records fault events, supports remote communication with DCS/SCADA, and realizes remote signaling, fault locating and power system automation. Optional arc flash protection protects switchgear busbars from arc explosion damage.

Comprehensive multi-stage protectionThree-stage three-phase overcurrent protection (low-set, high-set, instantaneous), two-stage non-directional earth fault protection, cable thermal overload protection, phase break protection, optional arc protection, breaker failure protection and trip circuit monitoringeero. Supports definite time and IDMT inverse-time curves compliant with IEC & IEEE standards.
Rich communication compatibilitySupports IEC 61850, IEC 60870-5-103, Modbus, DNP3, SPA bus, with RS485 and fiber communication options for docking with power automation systems.
Hardware advantagesPluggable modular design for quick replacement and easy cabinet retrofitting; front IP54 dust/water resistance, rear IP20; built-in LCD local display, multi-language menu and fault code prompts; complete self-check function for hardware faultsABB Group.
