Product Introduction
ABB REU615C-E HCUBCCAHABC2DNN11E is a compact numerical voltage protection and control relay developed for medium-voltage and high-voltage electrical distribution systems requiring dependable voltage supervision, frequency protection, and digital substation communication capability.
As part of ABB’s Relion® 615 family, the relay integrates protection, monitoring, event recording, automation logic, and communication functions into a withdrawable IED platform suitable for both new installations and retrofit switchgear projects. The 615 series was engineered around IEC 61850 interoperability, allowing simplified integration into modern digital substations and SCADA systems.
Compared with earlier ABB 610-series relays, the REU615C-E platform provides improved Ethernet communication, configurable application logic, advanced disturbance recording, process bus capability, and enhanced HMI functionality. Its withdrawable plug-in structure also simplifies relay replacement and maintenance procedures inside energized switchgear environments.
