Firmware update releases from Digital Substation Products

Firmware updates represent an integral part of ABB’s life cycle management of distribution protection and control relays. The updates ensure optimized usability throughout the relay’s entire life cycle by offering the latest improvements. The ideal time for a firmware update would be at device commissioning, during periodical testing or a maintenance break.

Available firmware updates are easily accessible for download through ABB’s data-sharing and backup service, Data Care. Accessing the firmware updates requires no user registration, only entering the relay’s serial number.
