Product Overview

The REU610 is a high-precision numerical voltage protection relay from the ABB Relion family, engineered for the comprehensive monitoring and protection of medium-voltage power distribution networks. This module is specialized in detecting voltage-based abnormalities, providing critical overvoltage, undervoltage, and residual overvoltage protection. By ensuring rapid fault isolation and deterministic performance, the REU610 safeguards transformers, motors, and busbar systems from potentially damaging voltage fluctuations. Its compact design and multi-protocol communication support make it an essential Intelligent Electronic Device (IED) for modern substation automation and industrial power management.
