Ubiquiti Ethernet Surge Protector Gen 2 (ETH-SP-G2)

The Ubiquiti Ethernet Surge Protector Gen 2 (ETH-SP-G2) is a high-performance network safeguard designed to protect sensitive Ethernet equipment from damaging electrical surges and electrostatic discharge (ESD). Built for both indoor and outdoor use, the ETH-SP-G2 is an essential addition to any network setup vulnerable to lightning strikes, power line anomalies, or sudden transient currents. Ideal for protecting routers, switches, access points, and Power over Ethernet (PoE) devices, this compact and rugged device supports 10/100/1000 Mbps connections and meets industrial-grade durability standards.

Product Features

Advanced Surge and ESD Protection

Absorbs and dissipates harmful transient currents and voltage spikes caused by lightning or electrical faults, shielding Ethernet-connected devices from damage.

High Discharge Current Capacity

Engineered to withstand and safely discharge surges of 10kA or more, providing robust protection in high-risk environments.

PoE Compatibility

Fully supports IEEE 802.3af PoE, safeguarding both data and power lines for PoE-enabled devices without interrupting network performance.

Durable and Weather-Resistant

Operates reliably across a wide temperature range (-30°C to 65°C) and humidity levels (10% to 90% non-condensing), making it ideal for outdoor and industrial deployments.

Vibration and Shock Certified

Tested to ETSI300-019-1.4 standards, ensuring resilience against physical stress, shock, and vibration commonly found in remote or rugged installations.

Plug-and-Play Deployment

Two RJ45 female ports support 10/100/1000 Mbps connections for seamless integration with standard Ethernet devices—no special tools or configuration required.
