When one Ethernet run carries a camera, access point, or control device, protection has to be simple and dependable. The Ubiquiti UACC-ETH-SP-DIN is a compact surge protection module designed for indoor installations where a single protected link matters more than bulk hardware. With bidirectional protection for up to 10 GbE and PoE++, it fits modern edge networks without forcing a compromise on speed or powered-device support. The 20 kA surge discharge rating gives the line a stronger buffer against transient electrical events, helping reduce the chance of damage to connected equipment. Its DIN rail and wall-mount installation options make it easy to place near the point of entry, in an enclosure, or alongside other control hardware. Multiple grounding points support cleaner installation practices in environments where grounding discipline matters. For teams protecting a single high-value link, this is the kind of component that earns its place by preventing a small event from becoming a service call, a replacement order, or an avoidable outage.
