Main Applications
This unit is the dedicated standalone HMI (SUE3000) for ABB REF542PLUS multifunction feeder protection and control device.
‑ Mounted on cabinet doors of 6‑35kV medium‑voltage switchgears. Widely applied in power substations, industrial power distribution rooms, industrial MV power‑distribution systems, GIS gas‑insulated switchgears and AIS air‑insulated switchgears.
‑ Used for local monitoring, parameter setting and equipment operation for feeder, transformer and motor protection bays. Provides full local maintenance capability when SCADA remote communication fails.
‑ Critical spare‑part for medium‑voltage relay‑protection systems for replacement of defective HMI panels of REF542PLUS protection terminals.
