Keep critical networked devices online when electrical noise and surge events threaten the line. Eaton Network Dataline Surge is designed to protect connected equipment from lightning, electrostatic discharge, and ground surges across a range of dataline environments. It supports RJ45 10/100Base-T, token ring, AS400/Sys3x, and RS422 applications, making it suitable for mixed infrastructure where older protocols still matter. This is the kind of protection that belongs in front of equipment you cannot afford to lose to a transient event. Use it to harden NICs, terminals, hubs, and similar endpoints that depend on stable signaling and clean line conditions. For teams maintaining legacy systems alongside modern Ethernet, the value is not just surge suppression — it is preserving uptime on devices that are often difficult or expensive to replace. Built for network-facing protection rather than general-purpose power distribution, this model addresses the specific risks that travel over data lines. That makes it a strong choice for environments where line integrity and equipment continuity matter more than commodity surge strips. When the cost of downtime includes lost transactions, interrupted operations, or field service calls, targeted dataline protection earns its place.
