Specialist Surge Protection for Ethernet Cat 6 Networks
Ethernet cabling is widely used to connect industrial automation equipment, security devices, network switches, wireless access points, IP cameras and other communications equipment. Although these connections normally operate at relatively low voltages, long cable runs and exposed wiring routes can provide a path for transient overvoltages to reach sensitive electronic interfaces.
The Finder 7P.68.9.060.0600 is designed to help protect compatible Ethernet networks against these disturbances. Installed in-line with the network cable, it provides surge suppression for all eight Ethernet conductors, helping limit transient voltage differences between individual lines and between the data lines and protective ground.
The device is specifically intended for Cat 6 Ethernet cabling and supports transmission frequencies up to 250 MHz. This allows it to be incorporated into compatible structured cabling systems while maintaining the frequency characteristics required for the intended network connection.
Its specified insertion attenuation of less than 2 dB at 250 MHz is an important consideration for data transmission performance. The actual operation of a complete network link also depends on cable length, connector quality, cable category and the electrical characteristics of the connected equipment.
The shielded RJ45 input and output connectors simplify installation and help maintain the shielding arrangement of compatible Ethernet cables. The aluminium chassis provides a durable enclosure, while the protective grounding arrangement allows common-mode surge currents to be diverted through the intended path.
Unlike a conventional mains surge arrester, this device is specifically engineered for Ethernet data line protection. It should not be used as a substitute for a 230 V AC power SPD or connected directly across mains power conductors.
Power over Ethernet Protection for Compatible Network Equipment
Power over Ethernet allows electrical power and network data to be transmitted through the same Ethernet cable. This technology is commonly used for IP cameras, wireless access points, VoIP equipment and industrial networking devices.
The Finder 7P.68.9.060.0600 is designed for compatible PoE applications, providing surge protection while allowing the Ethernet connection to carry data and power within the specified electrical limits.
The device has a 48 V DC nominal voltage, a 60 V DC maximum continuous operating voltage and a 500 mA nominal load current. These ratings must be checked against the actual operating conditions of the connected PoE equipment.
Not every PoE installation has the same electrical requirements. Higher-power PoE systems may use currents that exceed the nominal load current specified for this SPD. Compatibility should therefore be confirmed for the particular PoE standard, power sourcing equipment and powered device before installation.
When correctly selected and installed, the Finder 7P.68.9.060.0600 can provide an additional protective measure for Ethernet equipment exposed to transient overvoltages travelling along network cabling.
The Finder 7P.68.9.060.0600 provides Type 3 surge protection intended for installation near sensitive network equipment, typically at the boundary between LPZ 2 and LPZ 3.
Under the C2 test classification, the device has a 1.6 kA total nominal discharge current for line-to-protective-ground surges and a 200 A nominal discharge current for line-to-line surges, measured using the standard 8/20 µs waveform.
The specified C2 voltage protection level is 130 V line-to-line and 350 V line-to-ground. These values help engineers assess the protection characteristics of the device under the relevant surge test conditions.
Under C3 testing, the device has a 130 V line-to-line voltage protection level at a voltage rise rate of 1 kV/µs.
The specified 1 ns response time supports rapid reaction to transient overvoltages. However, effective protection depends on the complete installation, including grounding, cable routing and coordination with other surge protection devices.
Where a network cable runs between buildings or through particularly exposed locations, additional protective measures may be required at other points along the cable route. The Finder 7P.68.9.060.0600 should be selected as part of an appropriately designed surge protection system rather than treated as a guarantee against all lightning-related damage.
Straightforward RJ45 Connection and DIN Rail Installation
The Finder 7P.68.9.060.0600 uses shielded RJ45 input and output connections, allowing it to be installed in-line between the incoming Ethernet cable and the equipment requiring protection.
For effective protection, the device should be positioned as close as practicable to the protected equipment, with the grounding arrangement completed according to Finder's installation instructions.
The SPD can be mounted onto a standard 35 mm DIN rail according to EN 60715. Finder also specifies supplied accessories to support installation near the protected equipment.
The device's aluminium chassis and shielded RJ45 connectors are intended for professional data and communications installations. The cable shielding and protective ground connection should be arranged correctly to maintain the intended surge protection path.
Its IP20 protection rating means the device should be installed within a suitable enclosure or protected indoor location. It is not intended for unprotected exposure to rain, water ingress or other harsh outdoor conditions.
Before installation, confirm that the Ethernet link operates within the device's 60 V DC maximum voltage, 500 mA nominal load current and supported transmission characteristics.
Installation and inspection should be carried out by a competent professional following Finder's instructions and the applicable requirements for electrical safety, structured cabling and surge protection.
