Product Introduction
RED670 1MRK004810-CB is an ABB Relion 670 series protection IED for line and cable differential protection in transmission and substation applications. It is used on overhead lines, cables, transformer feeders, and block applications where selective fault detection matters.
The unit supports IEC 61850-based substation integration and is delivered pre-configured and type tested. That reduces commissioning time, but you still need to verify firmware revision, settings files, and any existing scheme-communication dependencies before swap-in.
