In an increasingly connected world, Ethernet networks form the backbone of businesses, homes, and data centers, handling everything from routine data transfers to critical communications. However, these networks are vulnerable to “back-door” surges—electrical spikes that travel through data lines rather than power cords, often caused by lightning strikes, utility fluctuations, or electromagnetic interference. Such surges can fry network interfaces, routers, switches, and connected devices, leading to costly downtime and repairs. Enter the APC ProtectNet Standalone Surge Protector for 10/100/1000 Base-T Ethernet Lines (model PNET1GB) from APC by Schneider Electric. This compact device is designed to shield Gigabit Ethernet ports from damaging surges while maintaining full network performance. In this blog, we’ll explore its features, specifications, benefits, installation, and why it’s a must-have for network reliability.
What is the APC ProtectNet PNET1GB?
The ProtectNet series is APC’s line of standalone surge suppressors tailored for data lines, including Ethernet, coaxial, and phone connections. The PNET1GB specifically targets 10/100/1000 Base-T Ethernet lines, which are standard in modern networking for Fast Ethernet (10/100 Mbps) and Gigabit Ethernet (up to 1000 Mbps). As a standalone unit, it doesn’t require integration with a UPS or power strip—it’s a plug-and-play protector that inserts directly into your Ethernet cable run.
Compatible with Power over Ethernet (PoE) applications, the PNET1GB ensures it won’t interfere with devices that deliver power through Ethernet cables, such as IP cameras, VoIP phones, or wireless access points. By diverting surge energy to ground, it prevents voltage spikes from reaching sensitive electronics, offering a layer of defense beyond traditional power surge protectors. This makes it ideal for environments prone to electrical instability, like offices near power lines or outdoor installations exposed to weather. As part of Schneider Electric’s ecosystem, it aligns with APC’s reputation for reliable power and data protection solutions.

Standout Features
- Comprehensive Ethernet Protection: Shields all eight wires of a standard RJ-45 Ethernet cable from surges, ensuring no data loss or hardware damage.
- PoE Compatibility: Allows power delivery over Ethernet without interruption, making it suitable for modern IoT and networked devices.
- Fail-Safe Design: Unlike many surge suppressors that fail “short” and continue passing power (leaving equipment vulnerable), the PNET1GB incorporates APC’s fail-safe mode. If compromised, it disconnects the line to prevent further damage.
- Ultra-Fast Response: With a 1 ns response time, it reacts almost instantaneously to transients, protecting against both large surges and multiple smaller events.
- Easy Inline Installation: Simply connect it between your network device and the wall jack or switch—no tools or configuration required. The included patch cable simplifies setup.
- Grounding Requirement: Must be connected to a properly grounded outlet or rack for optimal performance, emphasizing the importance of a solid earth ground in your setup.
The device is compact and wall-mountable, fitting neatly behind equipment or in patch panels. For full technical details, APC provides a specification sheet and user manual on their site.
Installation Guide: Setting Up the PNET1GB
Installing the PNET1GB is straightforward and takes just minutes, even for non-technical users. Based on APC’s guidelines, here’s a step-by-step process:
- Prepare Your Space: Ensure you have access to a grounded electrical outlet or rack ground. Power down connected devices if possible.
- Connect the Input: Plug one end of your Ethernet cable (from the network source, like a switch or router) into the PNET1GB’s input RJ-45 port.
- Attach the Ground Wire: Connect the provided ground lug or wire to a reliable earth ground point. This is crucial for diverting surge energy safely.
- Connect the Output: Use the included 15 cm patch cable (or your own Cat5e/Cat6 cable) to link the PNET1GB’s output to your protected device (e.g., computer, server, or PoE injector).
- Test the Connection: Power on devices and verify network connectivity. Run a speed test to confirm no performance loss—Gigabit speeds should remain intact.
- Secure Placement: Mount the unit if needed, using adhesive or screws, to prevent accidental disconnection.
APC recommends inspecting the ground connection periodically and replacing the unit if it shows signs of surge absorption (e.g., via visual indicators on some models). Always follow local electrical codes, and consult the user manual for diagrams.
Benefits of the APC ProtectNet PNET1GB
The PNET1GB offers more than basic surge protection—it’s a proactive shield for your network infrastructure.
