Ethernet Surge Protector (2 Pack) Gigabit PoE++ - 154W Protection

In this review of the Ethernet Surge Protector (2 Pack) the bottom line is simple: this is a workmanlike lightning arrestor for network gear that prioritizes robust transient protection and PoE compatibility over frills. It is best for installers and IT pros who need inline surge defense for routers, switches, cameras and modems and want a metal, grounded device that can handle high PoE currents. The single biggest reason to buy is its combination of gas discharge tube protection and a grounded aluminum housing that supports PoE++ up to 154W, offering peace of mind where lightning and surge exposure are real risks.

Key Features

• Gigabit compatibility: Supports 1000 Mbps Ethernet so it can be used on modern CAT5 and CAT6 runs without limiting network speed.
• High PoE support: Handles PoE++ transmission and up to 154W/48V so powered devices that draw significant current remain protected.
• Gas discharge tubes (GDT): Uses GDT lightning suppression to divert high-energy transients away from connected equipment for full-line protection.
• Robust metal housing: An aluminum case and metal shielded RJ45 help with durability and grounding in exposed installations.
• Grounding ready: Includes a 12AWG ground wire for proper earth reference and reliable line-to-ground protection.
• Bidirectional clamping: Provides line-line and line-ground protection and meets IEC 61000-4-5 with 20KA 8/20s surge handling.

Who It's For

The Ethernet Surge Protector is aimed at network installers, security camera technicians and small IT teams who need inline surge protection where surges or lightning are concerns. It is most useful for outdoor runs or edge devices like PoE cameras and APs where a grounded metal arrestor can be mounted and wired to a known earth point.

It is less appropriate for users who rely on nonstandard RJ45 wiring or who expect plug-and-play wall-mount convenience without any grounding work. Home hobbyists with no access to proper grounding or those who need a packaged consumer surge strip should consider alternatives.

Pros & Cons

Pros

• Solid build quality with an aluminum case and shielded RJ45 for durable field use.
• Protects differential pairs and supports IEEE 802.3 af/at/bt PoE modes including high-power PoE++.
• High surge rating (20KA 8/20s) and gas discharge tube technology give strong transient protection.
• Includes 12AWG ground lead for proper installation and reliable earth reference.

Cons

• Some users report issues with the nonstandard RJ45 socket and electrical connection, which can complicate installs.
• Requires proper grounding and basic wiring skill, so it is not purely plug-and-play for casual users.

Our Verdict

The Ethernet Surge Protector (2 Pack) is a practical, well-built option for professionals who must protect PoE cameras, switches and other network endpoints from lightning and surge events. Its GDT suppression, high surge rating and PoE++ support make it especially valuable in exposed installations where proper grounding is available; however, installers should be prepared for potential RJ45 fit issues and basic wiring work.

Frequently Asked Questions

Can this unit handle PoE++ devices?
Yes, it supports IEEE 802.3 af/at/bt and PoE++ transmission up to 154W/48V with specified current ratings for 2 and 4 pairs.

Does the protector reduce network speed?
No, it is designed for Gigabit Ethernet (1000 Mbps) and should not limit normal network throughput when correctly installed.

Is grounding required?
Yes, a proper earth connection using the included 12AWG ground lead is required for optimal protection and to meet the device design.
