The APC ProtectNet PNET1GB is a standalone surge protector for Ethernet data lines, specifically designed for 10/100/1000 Base-T networks. The device protects a single RJ45 port from harmful surges caused by lightning strikes, electrical disturbances, or other transients. It is compatible with Power over Ethernet (PoE) and is therefore suitable for networks that also supply power to end devices such as IP cameras or access points via the data cable. The device is gray in color and has compact dimensions of 47 mm width, 28 mm depth, and 104 mm height, making it easy to integrate into existing network infrastructures. It is supplied with a 15 cm long network patch cable, enabling direct connection between the protection device and the network device.

Applications
This surge protector is intended for use in offices, server rooms, industrial facilities, and other environments where network electronics must be protected from transient voltage spikes. Particularly sensitive components such as network cards in computers, switches, routers, or PoE devices benefit from the protection function, as these can be damaged even by relatively minor interference. The protection function is also relevant when data lines are routed near high-voltage lines, as this can induce voltage spikes. The device is designed for indoor use and can operate at temperatures from -15 °C to 65 °C and relative humidity from 0 to 95 %.

Features and Specifications in Detail
The APC PNET1GB offers protection against surges in both normal and common mode. The peak current in normal mode is 6.5 A, while the value in common mode is 0.25 A. These values refer to the maximum current the device can divert to protect connected equipment. The device's response time is 1 ms, meaning it reacts to a surge within milliseconds and diverts the voltage spike. The protection function is achieved through an integrated diversion device that safely diverts transient voltages without affecting data transmission. The device is designed for use in 10/100/1000 Base-T networks, ensuring compatibility with Gigabit Ethernet.

Technology Explained Simply
Voltage surges in data lines often occur due to external influences such as lightning strikes nearby, electrical disturbances in the power grid, or inductive coupling from high-voltage lines. These voltage spikes can damage sensitive network devices, even if they are protected by other measures such as power surge protection. The APC ProtectNet PNET1GB protects the data line directly at the connection point, eliminating a backdoor for surges. The diversion technology ensures that voltage spikes are quickly and safely diverted without interrupting data transmission. Compatibility with PoE means that power supply over the network cable is also protected, which is crucial for many modern network devices.

Compatibility and Accessories
The device is specifically designed for RJ45 network connections and protects a single data port. It is part of APC's ProtectNet family, which also includes protection devices for telephone and coaxial lines. Compatibility with PoE and 10/100/1000 Base-T networks makes it universally applicable in modern network infrastructures. The included 15 cm long patch cable enables direct connection between the protection device and the network device. Rack mounting is not provided, so the device is installed as a standalone unit at an appropriate location in the network.

Installation and Mounting
Installation is done by simply connecting the included patch cable between the network device (e.g., switch, router) and the APC ProtectNet PNET1GB. The other end of the protection device is connected to the network device (e.g., computer, IP camera). The compact design allows for flexible placement, for example on a desk, in a server room, or at a network switch. No special mounting or tools are required. The connection is made using standard RJ45 connectors, which are universally used in networks.

Operational Advantages
The APC PNET1GB provides reliable protection for sensitive network devices against transient surges, often caused by external influences. The fast response time of 1 ms ensures that damage is intercepted as soon as it occurs. Compatibility with PoE and Gigabit Ethernet allows use in modern networks without performance limitations. The device is robust and designed for indoor use across a wide range of temperatures and humidity levels. Simple installation and compact design facilitate integration into existing networks without additional effort.

Note on Color
Sources differ in specifying the device's color: Sources 1, 3, and 4 state gray, while Source 6 states beige. Due to this discrepancy, the color is not specified in the text to ensure clarity. The actual color depends on the product version and the source providing the information.
