ABB REF610C11HCNN01 is a mature multifunctional numerical feeder protection relay from ABB Relion REF610 platform, focused on comprehensive protection, accurate measurement and real-time monitoring for 6kV~35kV medium voltage distribution feeders including overhead lines and underground power cables.

Integrated multiple core protection logics including three-stage overcurrent, non-directional earth fault, thermal overload and multi-shot auto-reclosing, it works perfectly on solidly earthed and resistance-earthed distribution grids; optional arc fault detection function provides rapid busbar arc protection inside metal-clad switchgear. Its built-in programmable logic enables customized interlock and auxiliary control according to on-site operation requirement.

Adopting hot-swappable plug-in hardware structure, the core relay module can be pulled out for test or replacement while base stays fixed on panel, greatly simplifying commissioning and routine maintenance. This REF610C11HCNN01 variant is preconfigured with dual communication channels supporting Ethernet IEC61850 and RS485 Modbus, compatible with both new digital substation and legacy traditional distribution automation system.

Passed strict KEMA type test and DNV marine certification, the relay features wide-range universal auxiliary power supply and robust casing with front IP54 protection grade, suitable for inland industrial factory, urban power grid, mining site, offshore platform and vessel power distribution occasions. It also records over 500 pieces of timestamped fault event data for post-fault analysis and equipment troubleshooting.
