Mersen Solutions for Data Centers

Mersen is at the forefront of this growing market working to provide cutting edge technology products to help address customer needs. As the demand within these markets grows, unique product offerings from Mersen help meet the challenges faced by data centers and critical power infrastructure.

  • Making Data Centers more reliable.

    Mersen fuses play a critical role in ensuring the reliability and safety of electrical systems in data centre applications. Designed for high-performance and fast response, these fuses provide overcurrent protection to safeguard sensitive equipment such as servers, UPS systems, power distribution units (PDUs), and cooling infrastructure. In environments where uptime is essential, Mersen fuses help prevent electrical faults from escalating into costly outages or equipment damage. Their compact design, high interrupting ratings, and compliance with global standards make them well-suited for the dense and demanding electrical architectures typical in modern data centres. By minimizing downtime and enhancing system protection, Mersen fuses contribute significantly to the operational continuity and efficiency of mission-critical IT environments.

  • 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.
