Mersen Solutions for Data Centers

Mersen enables the safe, efficient, and reliable delivery of power from the grid to the GPU, helping data center operators scale today's infrastructure while preparing for tomorrow's AI-driven architectures.

  • Powering Today's Data Centers and beyond

    Artificial intelligence is transforming the data center industry. As AI workloads continue to grow, operators are facing unprecedented increases in power demand, rack density, cooling requirements, and electrical complexity. Traditional power architectures are evolving to support higher efficiency, greater reliability, and future-ready infrastructures.

    Mersen helps data center operators, OEMs, engineering firms, and critical power providers design and build reliable, efficient, and scalable electrical systems—from the utility grid to the server rack. Leveraging decades of expertise in electrical protection, bus bars, thermal management and capacitors, Mersen enables the next generation of high-density digital infrastructure.

  • Meeting the Challenges of AI-Driven Data Centers

    The rapid adoption of AI is changing every aspect of data center design.

    Higher-performance processors and GPUs require significantly more electrical power per rack than previous generations. As power density increases, so do cooling demands, electrical losses, and the need for highly reliable power delivery. At the same time, operators are exploring higher-voltage DC architectures, advanced power conversion technologies, and new approaches to improve overall energy efficiency.

    These evolving requirements demand more than individual components—they require an integrated understanding of the complete electrical infrastructure. Mersen supports customers in addressing these challenges with solutions that improve power reliability, optimize thermal performance, and prepare facilities for future electrical architectures.

  • Building the Data Center of Tomorrow

    The electrical architecture of data centers continues to evolve.

    As the industry moves toward higher-voltage DC distribution, solid-state transformers, silicon carbide power electronics, advanced liquid cooling, and increasingly dense AI clusters, infrastructure must be designed with flexibility and scalability in mind.

    Mersen is actively supporting these industry transitions by developing technologies that enable future-ready electrical systems while participating in initiatives that help shape tomorrow's data center standards.

    By understanding both current and emerging architectures, Mersen helps customers confidently prepare for the next generation of digital infrastructure.

  • Frequently asked questions:

    • Why are fuses critical in data centers?

      Fuses provide reliable short-circuit and overload protection with high interrupting ratings (AIR/IC). In data centers, they help maintain uptime by isolating faults rapidly (typically in less than ½ cycle), limiting let-through energy (I²t), and preventing arc flash propagation in accordance with IEC 60269 and UL 248 standards.

    • How do surge protective devices (SPDs) improve reliability?

      SPDs (per IEC 61643 and UL 1449) mitigate transient overvoltages caused by lightning, utility switching, or internal load changes. By clamping or diverting surge energy to ground, they protect servers, UPS systems, and networking hardware, reducing the likelihood of downtime or catastrophic failures.

    • What is the protection coordination strategy between fuses and SPDs?

      Fuses protect against sustained overcurrents and short-circuits, while SPDs address transient surges. Coordination is essential: fuses must not operate during a surge event unless the SPD fails. Correct selection ensures the SPD’s maximum continuous operating voltage (MCOV) and short-circuit current rating (SCCR) are compatible with the fuse and system design.

    • What are best practices for maintenance?
      • Replace fuses after operation with the correct type and rating.
      • Inspect SPDs regularly, as MOV-based devices degrade over time or after significant surge events.
      • Implement monitoring systems for SPDs (status indicators, remote signaling).
      • Follow NFPA 70B recommended practices for preventive maintenance.
