Description
⚡ ABB RED670 1MRK004810-DC is a Relion 670 series line differential protection IED designed for high-voltage transmission and distribution line protection. The specific ABB product ID 1MRK004810-DC corresponds to RED670 B32, Version 1.2, with a multi-breaker and single-phase tripping configuration. ABB documentation identifies RED670 as a dedicated line differential protection product for overhead lines and cable systems.
The relay provides fast differential protection using current measurements from multiple line ends and can be integrated into digital substation protection and control systems. The complete ordering code should be matched carefully when replacing an installed RED670 because different suffixes represent different hardware, protection, communication, and mounting configurations.

The RED670 family supports different line-differential configurations, including 3-CT and 6-CT arrangements for different numbers of protected line ends. ABB documentation also lists additional functions such as line-differential logic, breaker-failure protection, synchrocheck, and other configurable protection functions depending on the specific product configuration.
🔗 System Integration
The RED670 is intended to operate as part of a coordinated line-protection scheme. Current information from the protected line ends is exchanged between protection devices, allowing the relay to distinguish internal line faults from external faults. The 670-series platform also supports digital substation communication and IEC 61850-based applications in applicable configurations. ABB states that process-bus sampled values through IEC/UCA 61850-9-2LE were supported across the Relion 670 series from version 2.2.
For replacement applications, verify the complete 1MRK004810-DC product ID, hardware configuration, CT arrangement, communication interfaces, auxiliary power supply, firmware/application version, and existing PCM600 project before commissioning.
❓ FAQ
Q1: What is the ABB RED670 1MRK004810-DC?
It is a Relion 670 series line differential protection IED.
Q2: What does 1MRK004810-DC identify?
The product ID 1MRK004810-DC identifies RED670 B32, Version 1.2, with multi-breaker and single-phase tripping.
Q3: What is RED670 used for?
It is used for line differential protection of power transmission and distribution lines, including overhead lines and cable systems.
Q4: What does B32 mean?
For this product configuration, B32 corresponds to the multi-breaker / single-phase-tripping configuration identified in the ABB ordering documentation.
Q5: Does RED670 support IEC 61850?
The Relion 670 platform supports IEC 61850 communication, with specific communication and process-bus capabilities depending on the product version and hardware configuration.
Q6: Can another RED670 suffix be used as a replacement?
Not automatically. Different RED670 ordering codes can represent different breaker arrangements, analog systems, power supplies, HMI configurations, communication options, and protection functions. The complete product code should therefore be compared before substitution.
