Protecting Data Center Ethernet Infrastructure

- To protect critical Ethernet infrastructures: using surge and lighting protection for structured cabling systems (including industrial Ethernet, PoE, 4PPoE) to prevent transient voltages and lightning‑related surges is imperative.
- High‑performance features including compatibility with speeds up to 10 Gbit/s, lightning current capability up to 4 kA (10/350 µs), compact DIN‑rail mount design, and visual (green/red) status indicators for simple monitoring.
- Versatile across applications: suitable for data center Ethernet infrastructure as well as security systems, building automation, e‑mobility charging, or other industrial facilities where Ethernet communications must be maintained and downtime minimized.
In today’s connected world, protecting critical data and communication systems from power surges and lightning strikes is more essential than ever. Electrical surges can damage sensitive equipment, cause costly downtime, and compromise the integrity of entire networks. As digital infrastructure expands across data center ethernet infrastructure, industrial automation, as well as smart building systems, the need for reliable surge protection continues to grow. Effective surge and lightning protection helps ensure system availability, safety, and also long-term equipment performance.
