Reliability at the heart of nuclear energy: the story of the 7000 CEE range

For over five decades, the 7000 CEE range has embodied ICE SAS’s technological excellence in the service of the nuclear industry.

Developed in 1973, this range of protection relays has become a trusted solution for the most demanding environments.

These relays support leading players — EDF, Engie Electrabel, and international partners such as KHNP — with one shared mission: ensuring the safety and reliability of electrical systems within nuclear power plants.

Built to last, the 7000 CEE relays combine:

• Reliability – consistent performance in extreme conditions.
• Robustness – design meeting the strictest nuclear standards.
• Durability – integration into our Long-Term Supply (LTS) program, ensuring operational continuity over time.

At ICE SAS, we remain true to one conviction:

“In the nuclear field, safety leaves no room for compromise.”
