The Ubiquiti ETH-SP-G2 Ethernet Surge Protector is a robust, passive device engineered to safeguard any Power-over-Ethernet (PoE) or non-PoE network equipment against electrostatic discharge (ESD) and power surges. Designed specifically for outdoor high-speed networks, it supports connection speeds of up to 2.5 Gbps, ensuring reliable protection without compromising data throughput.

Featuring two surge-protected RJ45 female connectors, the ETH-SP-G2 provides inline protection that effectively diverts harmful voltage spikes to ground, preventing device damage during electrical surges caused by lightning or switching events. Its durable polycarbonate enclosure is weather-rated with an IPX5 ingress protection, making it suitable for harsh outdoor environments.

This compact unit measures 91 x 61 x 32.5 mm and weighs approximately 80 grams, supporting operating temperatures from -30°C to 65°C and humidity conditions between 10% and 90% non-condensing. Certified for shock and vibration resistance (ETSI300-019-1.4 standard), it ensures long-term reliability in demanding installations.

Ideal for deployment near outdoor network devices or building entry points, the ETH-SP-G2 requires a proper ground connection to safely channel surge energy. Ubiquiti recommends using two surge protectors for optimal protection strategies (one at the device and one at the entry point).
