Product Overview

REU610AVVHCNN is ABB Relion 610 series multifunction voltage‑protection relay for medium‑voltage distribution substations, transformer and capacitor‑bank protection, motor undervoltage supervision and islanding‑condition detection for distributed‑generation connectionsABB Group. It performs over‑voltage, under‑voltage and residual‑voltage earth‑fault measurement and protection functions. Local front‑panel HMI enables parameter setting, measured‑value viewing and fault‑event log browsing. Multiple standard communication protocols support substation‑automation SCADA integration. Product status is end‑of‑life since 2017; available as refurbished and surplus tested spare relays for switch‑gear retrofit‑and‑maintenance projectsABB Group.

Application Notes

‑ Install according to ABB REU610 technical‑reference‑manual wiring diagrams. ‑ Set auxiliary supply voltage jumper correctly before power‑on. ‑ Perform secondary‑injection protection‑relay function test after replacement. ‑ Typical deployment: utility‑distribution substation voltage‑protection‑relay spare‑part stocking.
