The Ubiquiti Ethernet Surge Protector Gen 2 (ETH-SP-G2) is designed to protect Ethernet equipment from power surges, including transient voltages, which can be caused by lightning strikes, power line crosses, or other electrical anomalies. It’s an essential component for safeguarding network devices such as routers, switches, and access points, especially in outdoor or remote environments where equipment is vulnerable to surges.

Product Features

Surge Protection

• ESD/EMP Protection: The ETH-SP-G2 absorbs transient currents and offers surge protection for Ethernet lines. It can handle surge voltages from 100V/s to 1kV/µs, providing a high level of protection for sensitive networking equipment.
• DC Spark-Over Voltage: It can handle 90V @ 100V/s of spark-over voltage, preventing damage to devices.
• Maximum Impulse Spark-Over Voltage: Protects against spikes up to 700V @ 1kV/µs.

High Discharge Current Capacity

• Discharge Current: The ETH-SP-G2 can handle a discharge current of 10kA+, which is significant enough to withstand powerful surge events.

Data Line Protection

• RJ45 10/100/1000 Ethernet: It offers protection for both data and power lines (including Power over Ethernet – PoE) using RJ45 connectors, making it compatible with most modern Ethernet networks.

PoE Support

• Fully supports IEEE 802.3af PoE, ensuring the protection of both data and power over Ethernet lines simultaneously.

Environmental and Mechanical Durability

• Operating Temperature: It is rated to function in temperatures ranging from -30°C to 65°C (-22°F to 149°F), ensuring reliable operation in a wide variety of climates.
