ABB RED670 1MRK002810‑AC Relion 670 Series Line Differential Protection IED

Product Overview

The ABB RED670 1MRK002810‑AC is a high‑performance line differential protection IED belonging to the ABB Relion 670 platform. It is designed for high‑speed selective protection of overhead transmission lines, cable feeders and multi‑terminal lines up to 5 terminals, also applicable for lines with integrated power transformers. It integrates differential protection, distance protection, backup overcurrent protection, breaker control, disturbance recording and comprehensive substation communication interfaces. It is widely used as spare‑part for maintenance, retrofitting and refurbishment of existing power plant and utility substation protection panelsManualsLib.

Series

Relion 670 Series. This modular IED family covers line protection, bay control, transformer protection and generator protection devices for transmission and distribution substations. The series supports IEC 61850 digital substation standard, flexible application configuration and unified PCM600 engineering tool for power system protection applications.
