Product Introduction
ABB REU610 CVVHCNR02 is a numerical voltage protection relay developed for electrical systems requiring stable voltage supervision, fast alarm response, and dependable protective tripping. It is commonly installed in utility substations, industrial power distribution systems, feeder panels, and capacitor bank protection schemes.
The relay integrates overvoltage, undervoltage, and residual overvoltage protection functions into a compact protection platform suitable for both new installations and retrofit projects. In practical field applications, REU610 remains widely used where stable voltage monitoring and straightforward maintenance are more important than advanced IEC 61850 digital substation functions.
Its compact housing, relatively simple engineering structure, and ABB 610-series compatibility make it suitable for upgrading older protection panels while minimizing wiring modifications. Exact hardware revision, auxiliary supply range, and communication configuration should always be verified before commissioning or replacement.
